AB  - Developing efficient methods for Mn separation is the most challenging in exploring innovative and sustainable acid mine drainage (AMD) treatments. The availability and capacity of certain waste materials for Mn removal warrant further exploration of their performance regarding the effect of process factors. This study addressed the influence of AMD chemistry (initial pH and concentrations of Mn, sulfate, and Fe), the solid/solution ratio, and the contact time on Mn separation by wood ash (WA) and bone char (BC). At an equivalent dose, WA displayed higher neutralization and Mn removal capacity over the initial pH range of 2.5–6.0 due to lime, dicalcium silicate, and fairchildite dissolution. On the other hand, at optimal doses, Mn separation by BC was faster, it was less affected by coexisting sulfate and Fe(II) species, and the carbonated hydroxyapatite structure of BC remained preserved. Efficient removal of Mn was feasible only at final pH values ≥ 9.0 in all systems with WA and at pH 6.0–6.4 using BC. These conclusions were confirmed by treating actual AMD with variable doses of both materials. The water-leaching potential of toxic elements from the AMD/BC treatment residue complied with the limits for inert waste. In contrast, the residue of AMD/WA treatment leached non-toxic quantities of Cr and substantial amounts of Al due to high residual alkalinity. To minimize the amount of secondary waste generated by BC application, its use emerges particularly beneficial after AMD neutralization in the finishing step intended for Mn removal.

AB  - Thermo-chemical conversion via the pyrolysis of cigarette butt (CB) filters was successfully valorized and upcycled in the pre-carbonization and carbonization stages. The pre-carbonization stage (devolatilization) of the precursor material (cellulose acetate filter, r-CAcF) was analyzed by micro-scale experiments under non-isothermal conditions using TG-DTG-DTA and DSC techniques. The results of a detailed kinetic study showed that the decomposition of r-CAcF takes place via complex mechanisms, including consecutive reaction steps and two single-step reactions. Consecutive stages include the α-transition referred to as a cellulose polymorphic transformation (cellulose I → II) through crystallization mechanism changes, where a more thermodynamically ordered system was obtained. It was found that the transformation rate of cellulose I → II (‘cellulose regeneration’) is strongly affected by the presence of alkali metals and the deacetylation process. Two single-step reactions showed significant overlapping behavior, which involves a nucleation-controlled scission mechanism (producing levoglucosan, gaseous products, and abundant radicals) and hydrolytic decomposition of cellulose by catalytic cleavage of glycosidic bonds with the presence of an acidic catalyst. A macro-scale experiment showed that the operating temperature and heating rate had the most notable effects on the total surface area of the manufactured carbon. A substantial degree of mesoporosity with a median pore radius of 3.1695 nm was identified. The presence of macroporosity on the carbon surface and acidic surface functional groups was observed.

AB  - This work provides detailed mechanistic analysis of thermo-oxidative degradation behavior of vitamin D3—Ca (CaCO3 form) solid state supplement formulation. Analytical techniques such Attenuated Total Reflection Fourier-transform Infrared (ATR-FTIR) spectroscopy and Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry (MALDI-MS) were used for analysis of homogeneity of active pharmaceutical ingredients (APIs) throughout excipients contained within solid dosage forms. Information gained from MALDI-MS experiments was used to improve and better understand interactions present, later clearly disclosed through kinetic modeling. It was found that process mechanism proceeds via two single-step unbranched reactions and two steps of consecutive reactions. Key features include vitamin D3 meltings and degradation via hydrogen abstraction followed by addition of oxygen forming 1-hydroxy-vitamin D3 and further through its dehydration to 1-keto-vitamin D3. Identified product 1-hydroxy-vitamin D3 is substantial for enhancing the immune response of human body in fight against respiratory viruses. Another two degradation products, namely pyrocalciferol and isopyrocalciferol, produced by thermal isomerization at higher temperatures, were also identified. These vitamin epimers have crucial role in functioning of immune cells. Degradation process of mineral structure occurs through water molecules removal, forming anhydrous polymorph of CaCO3, where formation of solid (CaO) and gaseous (CO2) products participates in kinetically stabilized additive-functionalized amorphous CaCO3 crystallization. Confirmation of correctness of proposed degradation mechanism was verified by modulated dynamic (MD) predictions. Information obtained is valuable and suitable for safety evaluations of given supplement, but also could be applied for solid state forms, which are generally sensitive to oxidative conditions. © 2023, Akadémiai Kiadó, Budapest, Hungary.

AB  - This paper considers possible uses of fruit-based waste for the production of valuable chemicals and biofuel precursors through recycling by thermochemical conversion. Slow pyrolysis of goji berry mesocarp as sugar-riched feedstock was investigated using simultaneous thermal analysis measurements in non-isothermal conditions. This work announced that pyrolysis of goji berry mesocarp represents a promising route to obtaining an important key platform chemical - 5-hydroxymethylfurfural (5-HMF). To establish the process mechanism, two kinetic approaches were used for kinetic parameters determination: first, Friedman’s and Vyazovkin’s model-free (inverse) methods supported by numerical optimization of the process, and second, the model-based (direct) method. Model-free results showed a complex evolution of activation energy with conversion, indicating a multi-step mechanism. It was found that autocatalytic dehydration of fructose (in the presence of Lewis acids) is responsible for the production of 5-HMF at a low heating rate (5.0 K/min) with a maximum 5-HMF theoretical yield of 63.20 %. Higher heating rates (10.0 K/min and 15.0 K/min) trigger the fructose autogenesis behavior which opens the transferability channel to glucose (substrate) engagement for 5-HMF theoretical high yield production. It was revealed that differences between kinetic parameters are a consequence of the change in the mechanism of glycosidic bond cleavage. The validity of the proposed reaction mechanism scheme and accuracy of kinetic parameters was confirmed by modulated dynamic predictions.

AB  - Biomass is considered as an important renewable resource, which plays a key role in the development of sustainable energy systems. Biomass can be converted into energy or valuable chemicals by combustion, liquefaction, pyrolysis and gasification. Among these processes, thermal gasification “decomposes” biomass into the light chemical species at high temperatures, which can be applied to biomass with the greatest diversity. As the final (target) product of biomass gasification, syngas or gas rich in hydrogen (H2), are very important intermediate products in the petrochemical industry. However, the problematic tar produced during gasification could bring a number of problems. Catalytic biomass gasification is a promising strategy to significantly alleviate these problems. Transition metal-based catalysts for catalytic biomass gasification have been studied in recent decades. This review discusses various transition metal catalysts for biomass gasification, including nickel (Ni)-based monometallic and bimetallic catalysts and other Fe- and Pt-based catalysts. The performance of these catalysts is evaluated based on the applied reaction parameters, the quality of the syngas produced, and the tar reduction performance. Applications of DFT (‛Density Functional Theory’) calculations and AI (‛Artificial Intelligence’) to study biomass gasification mechanisms are summarized, and the cause of catalyst deactivation and regeneration of spent catalysts are also discussed. Likewise, in this review, the development potential of catalytic gasification of biomass in the Republic of Serbia was considered.

AB  - Low-rank coal, characterized by its high moisture, ash, and volatile matter content, besides the significant contribution to GHG emission, can be challenging to combust efficiently. Biomass, on the other hand, is a renewable energy source that can enhance combustion performance and reduce emissions. The transition from fossil fuels to renewables should involve the co-combustion of coal and biomass which requires a detailed understanding of their individual and combined combustion kinetics. In this paper, the model-based kinetic modelling approach is applied to studying the thermal decomposition of coal and biomass using a combination of experimental data and mathematical models. By quantifying the rates at which various components of these fuels degraded and release heat, the optimization of process parameters, enhanced energy efficiency, and minimized environmental impacts could be achieved. The obtained results presented in the manuscript offers several advantages in comparison with the standard fuel characterization techniques. For example, the non-additive issues for different fuel characteristics could be overcome. Furthermore, the ability to predict combustion behaviour under different operating conditions, optimize burner designs, and develop cleaner combustion technologies could be enabled. In that sense, performed research in this paper could further supports the transition towards sustainable and carbon-neutral energy systems by harnessing the energy potential of low-rank coal while utilizing biomass as a clean and renewable co-fuel.

AB  - The aim of the article is to show the effects of the main gasifier operating parameters, such as temperature, equivalence ratio, steam-to-fuel ratio, and gasification medium selection, on the gasification performance of sewage sludge. Using the developed one-dimensional mathematical thermodynamic equilibrium model for plasma and fluidized bed gasification, a comprehensive parametric study is established. The model is based on the principle of the minimum of the Gibbs function and uses only the ultimate and proximate analysis data as input to the model. The output of the model gives the equilibrium composition of the gasses produced. When comparing different gasification media, gasification with water steam gives a higher yield of H2 and CO in the syngas produced. Further comparison of the two gasification processes in terms of energy consumption is shown. The collected results can be useful in further analysis of the gasification processes, such as energy and exergy analysis and kinetics.

AB  - The actual paper analyses the performance of different energy crop biomasses, Miscanthus x giganteus Greef et Deu (EC-1) and Arundo donax L. (EC-2) stems, during slow pyrolysis process monitored by simultaneous TG-DTG-MS techniques, through chemical exergy analysis. In addition to considering the physical and chemical characteristics of given feedstocks for their efficient thermo-chemical conversion into pyrolytic gas, in this study, a theoretical simulation for their implementation use in the gasification process was also performed. The performed thermodynamic study with detailed exergy analysis showed that the large contribution of exergy in syngas components such as CO and H2 originates primarily from cellulose pyrolysis of EC-1, while large exergy contribution in syngas component as CH4 originates from lignin pyrolysis of EC-2. It was founded that the exergy efficiency of syngas for EC-1 equals 19.04%, which is lower than the exergy efficiency of syngas for EC-2 (20.46%), as a result of higher ash content in EC-1. Also, it was reported that higher carbon (C) and hydrogen (H) contents present in the EC-2 sample generate higher gaseous energy and exergy values, i.e. the increment of exergy efficiency of syngas, by both approaches (pyrolysis and gasification exergy analysis), but results in a lower biomass chemical exergy (18.28 MJ kg−1). The methodology applied to the gasification process was shown a higher exergy efficiency for EC-2 (∼36 – 42%) than for EC-1 (∼33 – 39%), dependant on the equivalence ratio (ER).

AB  - This work provides insight into possibilities of maximum utilization of C3-C4 energy crops for thermo-chemical conversion (slow pyrolysis) into high value biochemicals, platform chemicals, drop-in fuels and combustible gases, using coupled kinetic and thermodynamic analyses. In order to examine the kinetics of decomposition of lignocellulosic components, model-free and model-based methods faded from thermal analysis data were used. Thermodynamic compensation was used for explicatory of entropy controlled process, where conformational changes and chemical exchange directly affect the type and distribution of obtained pyrolytic products. It was shown that external variable (i.e. the heating rate/temperature) does not change either an entire reaction mechanism (mechanistic nature of MG and AD pyrolyses) or transition state, but it changes activation enthalpy and activation entropy which lead to differences in terms of heat energy consumption, pyrolysis favorability and thus rates of generation of activated complex among feedstocks. To investigate the interplay of catalysts (present in feedstocks as minerals) and reactants, selective energy transfer (SET) model was applied. The model showed an activity of catalyst with different outputs towards two reactants, lignin part of the structure in MG and 1,8-cineole in AD. It was shown that AD is more convenient for thermal conversion than MG, regarding to lower transformation energy requirement, higher reactivity, as well as much faster accumulation of products. © 2023 Elsevier B.V.

AB  - In recent years, deep eutectic solvents (DESs) have attracted considerable attention, and they have been applied in many fields, such as dissolution and separation, electrochemistry, materials preparation, reaction, and catalysis. In this paper, a detailed thermal decomposition mechanism of DES-type II (consisting choline chloride (ChCl) and magnesium chloride hexahydrate (MgCl2·6H2O) in a molar ratio 2:1 (MgCl2·6H2O-[Ch]Cl)) was explained, using thermal analysis techniques. Physicochemical clarification of overall thermal decomposition mechanism and the influence of enthalpy–entropy compensation (EEC) on reactions mechanism emerging are presented for the first time, in favor of this DES type. In the kinetic analysis of the decomposition process, two approaches were used: model-free (inverse) and model-based (direct) methods. It was found that thermodynamic principles in the form of EEC are the source of kinetic compensation effect (KCE) during MgCl2·6H2O-[Ch]Cl thermal decomposition, as a consequence of the effects of molecular interactions. Key phenomenon in the complex multiple step process represents a parallel dehydration steps of MgCl2·6H2O in DES, leading to formation of intermediates, such as [MgCl1(H2O)5]1+ and [MgCl2(H2O)4]. It was established that formation of final products (Mg(OH)2 and MgOHCl) requires a higher expenditure of energy to overcome a high potential barrier, where reaction system compensates this energy via hydrogen bonding disruption. This was confirmed by the identification of a specific ‘oscillator’, flagged as Hsingle bondOsingle bondH···Cl hydrogen bond donating system of the energy (“heat bath”). All kinetic parameters and mechanisms of individual reaction steps were confirmed by numerical optimization of the process and modulated dynamic predictions.

In order to obtain accurate results, the precise measurement of sample mass and temperatures are crucial. For that reason, the development of thermo-analytical (TA) techniques was conditioned by development of sufficiently precise instruments for measuring temperature and other characteristics of substances, such as changes in mass, enthalpy (heat), deformation, dimensions, electrical and magnetic properties. In this chapter, emphasis was placed on the description of the operation of thermogravimetric (TG) analyser and the influence of various experimental parameters on the quality of measurements in different reaction atmospheres. In regard to diversity of biomass sample properties, special attention is given to the adaption of experimental procedures for biomass thermal characterization by non-isothermal TG-runs. It was considered the impact of sample homogeneity determined by proper mechanical preparation. Additionally, the application of the calibration procedures and baseline correction measurements for obtaining more precise output data was shown. The study of the measurement accuracy, together with the reproducibility and repeatability required for the accurate thermal characterization of biomass samples by TG were implemented. © 2023 Nova Science Publishers, Inc.

AB  - Pyrolytic tire (PT) chars were first produced from waste car tires (WCT) through carbonization process at 800 °C, for different retention times. Then, best PT-char sample by its physicochemical properties (WCT 800(1 h)) was further tested for its ability to adsorb Rhodamine B (RhB) dye from aqueous solutions. Structural characterization of synthesized material showed existence of graphene-based material, with average pore diameter of 22.8 nm and specific surface area of 55.8 m2·g−1. Obtained carbon material meets specifications of commercial carbon black (CB). The yield of 33.6% of CB recovered has been achieved. Under the optimal conditions, 99.57% of RhB was removed. Adsorption of RhB obeys pseudo second-order model and Langmuir isotherm model. DFT (the density functional theory) was revealed that effective bonding of RhB onto WCT 800 originates from π-electron interactions with aromatic moieties and chemical (or at least the electrostatic) interactions, between positive nitrogen and electron-rich surface groups.

AB  - This paper considers possible uses of fruit-based waste (Goji berry mesocarp (GBM)) for the production of key platform chemicals (5-hydroxymethylfurfural (5-HMF)) through thermochemical conversion via slow pyrolysis, which was performed using simultaneous thermal analysis (STA). Originality and significance of this research is reflected in novel insights of fructose molecule role in the production of 5-hydroxymethylfurfural (5-HMF) through structural characteristics, manifesting reciprocal catalysis behaviour in an endergonic reaction pathway, giving high energy products. Based on proposed experimental and theoretical networks, the unwanted side products are totally blocked, where established results in this research clearly show advantages of synergistic work of the substrate molecule (glucose) and pseudo-catalyst (fructose) for the effective production of 5-HMF. The fructose self-repaired (isomerization) cycle through ‘open’ to ‘closed’ structure organization was explained as the key factor, which was responsible for the fructose effective autocatalytic lineage to the desired product, interpreting high yields of 5-HMF.

AB  - This work considers possible uses of fruit-based waste for the production of valuable chemicals and biofuel precursors through recycling by thermochemical conversion. Slow pyrolysis of Goji berry mesocarp (GBM) as sugar-rich feedstock was investigated using simultaneous thermal analysis (STA) measurements in non-isothermal conditions. Results reveal that pyrolysis of GBM represents a promising route to obtain important key platform chemical - 5-hydroxymethylfurfural (5-HMF). It was found that autocatalytic dehydration of fructose (in a presence of Lewis acids) is responsible for production of 5-HMF at a low heating rate (5.0 K/min) with a maximum 5-HMF theoretical yield of 63.20 %. Higher heating rates (10.0 and 15.0 K/min) trigger fructose autogenesis behavior which opens the transferability channel to glucose engagement for 5-HMF theoretical high yield production.

AB  - The pyrolysis of [4-(hydroxymethyl)phenoxymethyl]polystyrene (Wang) resin was studied by dynamic simultaneous thermogravimetric analysis (TGA) and derivative thermogravimetry techniques. The studied resin is used as the most commonly polymer supports in the peptide synthesis. A developed experimental master plots (exp-MP) model is presented that can be used to describe in more detail the pyrolysis of the resin established upon 4-hydroxybenzyl alcohol (PHB) on polystyrene, occurring throughout TGA experiments. This model assumes that the Wang resin is pyrolyzed through three parallel independent reaction steps, whereby their separation was performed through deconvolution procedure of the complex conversion rate curves. The mechanistic nature of each stage of Wang resin pyrolysis was explained by applying a combination of kinetic models such as diffusion mechanism, random nucleation and subsequent growth and chemical reactions mechanisms. The kinetic triplet parameters obtained in the present paper were then compared with those available in the literature. Within this kinetic study, the fraction distribution analysis (via distributed reactivity model) was performed, enabling reliable prediction of liquid products produced during the pyrolysis of the solid support of the Wang resin.

AB  - Sustainable development and mitigation of the climate changes are one of the main challenges of the circular economy, while the use of food industry residues could make an important contribution in tackling these challenges. In order to improve energy efficiency aspects of the industry residue treatment, generally, the drying process as the first step of the entire processing chain should be further analyzed. Regarding this, a comprehensive kinetic study was performed to provide the detailed mechanism of moisture removal from base raw material. Industrial residues from apple juice production were used for isothermal thermogravimetric analysis in the air atmosphere at different temperatures. Based on experimental data, different kinetic models were applied to determine kinetic parameters and dominant conversion functions. The dependence of the activation energy evaluated by Friedman’s isoconversional method on the conversion degree shows that the drying process is complex one. The mechanism of drying process and corresponding kinetic parameters were determined by multivariate nonlinear regression program (model-based analysis) and checked by modulated isothermal prediction (for quasi-isothermal conditions) and the isothermal prediction (for different isothermal conditions) tests. It was pointed out that temperature-dependent reaction step controlling overall mechanism represents releasing of CO2 which can suppress autocatalytic action of the ethylene, influencing the flavor and texture changes of the apple tissue. Obtained results can be used for prediction of the life-time of studied material, corresponding to selected temperatures and different conversion levels.

AB  - The presented paper deals with the influence of the heating rate on combustion characteristics (reactivity and reactivity evaluation, ignition index (Di), burnout index (Df), the combustion performance index (S), and the combustion stability index (RW)) of the protective coronavirus face masks. Two types of commonly used face masks in different state (new and exploited) were investigated by TG-DTG analysis in an air atmosphere, directly coupled with mass spectrometry (MS). Based on the experimental results, the impact of ultimate and proximate analysis data on the evolved gas analysis (EGA) was discussed. Also, the derived values from thermo-analytical (TA) data were compared with the literature reports, related to individual constitutive face mask materials. According to the performed research, it was established that different maximal reaction rate values at various heating rates indicate the complex nature of coronavirus face mask thermo-oxidative degradation, which is stimulated with carbon oxidation reactions and volatile matter (VM) release. By detailed analysis of obtained TG-DTG profiles, it was established that process takes place through the multiple-step reaction pathways, due to many vigorous radical reactions, causes by polymers degradation. The performed research was done to evaluate the possible utilization of coronavirus waste to energy production and sustainable pandemic environmental risk reduction.

AB  - With the increased popularity of using wood stoves for household heating in recent years, numerous experimental research projects have been launched with the goal of generating cleaner and more efficient stove designs. This work is focused on mathematical modeling of combustion process in low-power residential heating appliance (small-scale stove) fuelled by different wood pellets (WP1-Beech (hardwood) and WP2-Pine (softwood)). Kinetic model scheme that encompasses determination of Arrhenius parameters was proposed for applied Finite rate/Eddy Dissipation approach. Types of wood pellets have been combusted on the experimental stand which is equipped with a set of temperature sensors and exhaust analyzer. A comparison of results obtained from combustion in the heating unit has been performed to find relations between established kinetics of devolatilization for various wood pellets and to determine exhaust composition, arising from oxidation reactions. Numerical modeling using computational fluid dynamics (CFD) has been performed for the char and CO oxidations to supplement the experimental results. Due to limitations on installed stove such as poor design, air supply, fume extraction, or heat exchanger can lead to excessive CO emissions or lower energy efficiency. Outcomes show that it is crucial to minimize unused stove volume and to enhance gaseous mixing for reduction of CO emissions, while maintaining sufficiently high temperatures for supporting fast oxidation reactions. Results of comparisons of conducted analyses can be useful in areas related to process optimization and improvement of combustion and devolatilization reaction conditions in the small scale heating units.

AB  - The preliminary thermogravimetric studies of co-pyrolyzed low rank coals (lignites Kostolac and Kolubara) with waste materials (spent coffee ground and waste rubber granulate) in a form of blends have been performed. Thermal analysis measurements of blend samples were carried out in a nitrogen, atmosphere at three different heating rates of 10, 15, and 20 K per minute. The coal-waste blends were prepared in the percentage ratios of 90:10, 80:20, and 70:30. This work analyzed the synergy analysis for considered blends shown via descriptive parameters during co-pyrolysis process. According to the performed analysis, the presence of synergistic effect was identified, where strong interactions were also observed. For lignite-spent coffee ground blends, it was found that two factors which affect the synergy effect with coal are concentration of added biomass material and the heating rate. For lignite-tire rubber granulate blends, the blending ratio take on a decisive role for positive consequences of a synergistic effect (ratios below 30% of tire rubber granulate in coals are desirable). Also, in this work the influence of micro-scale condition parameters such as heating rate (as the experimental regulatory factor) was analyzed on the magnitude response of synergism during co-pyrolysis.

AB  - One of the goals that mankind has set for 2050 is decarbonization in the energy sector. For thatreason, the use of hydrogen as an alternative fuel looks like a possible solution. However, the conventionalhydrogen production process (electrolysis) now indirectly accounts for more than 2% oftotal global CO2 emissions. One of the scenarios to reaching set targets involves the decarbonizationof hydrogen production, resulting in green hydrogen. The one of the pathways for production of greenhydrogen is feasible within the gasification of lignocellulosic materials (biomass feedstock) into syngas.However, different feedstock parameters have an impact on the thermochemical conversion processi.e. syngas yield and composition. This paper presents the novel semi-quantitative analysis offundamental experimental data obtained by thermogravimetry and mass spectrometry. According tothe proposed methodology on the lab-scale level is possible to evaluate the feedstock quality for identificationof syngas yield and composition, with special attention to the hydrogen content in the syngas.The experimental results for two biomass samples were presented and based on performed semiquantitativeanalysis the evaluating of the possibilities for using considered feedstocks for green hydrogenproduction was done. Further discussions and comparisons with literature data were alsopresented.

AB  - This paper provides insights into understanding the physical and chemical changes that take place during re-heating process of Poplar fluff bio-char derived by carbonization at high operating temperature (850 °C). Bio-char re-heating experiments were performed by simultaneous TGA-DTG-DSC techniques in N2 atmosphere at 5, 10, 15 and 20 °C min−1. Kinetic modeling of the process was done through implementation of model-free and model-based approaches. It was identified that re-heating process contains two stages. The first was described by single consecutive reaction step (up to 200 °C) which is attributed to removal of physisorbed moisture at surface and in pores of carbonized material, while second was described by multiple reactions, including one consecutive step and two competitive steps. In the last, consecutive pathway includes reduction of PAH compounds (400–600 °C) into smaller ones, changing degree of condensation of carbon structure continuously. Competitive steps encompass competition between C10H8 (naphthalene) (700–780 °C) and C9H8 (indene) (700–750 °C) molecules decomposition. It was found that used heating rates have great influence on regulating the amount of gaseous (combustible) products from these reactions. It was established that internal heat and mass transfer processes control the release of products. Changing the pyrolysis mechanism with temperature of carbonized bio-char is the main factor for occurrence of true kinetic compensation effect, which is also discussed by applied isothermal life-time analysis. © 2021 Elsevier Ltd

AB  - The presented paper deals with the influence of heating rate on combustion characteristics (reactivity and reactivity evaluation, ignition index (Di), burn-out index (Df), combustion performance index (S), and combustion stability index (RW)) of protective coronavirus face masks. Two types of commonly used face masks in different state (new and exploited) were investigated by TG-DTG analysis in air atmosphere, directly coupled with mass spectrometry (MS). Based on experimental results, the impact of ultimate and proximate analysis data on the evolved gas analysis (EGA) was disscused in detail. Also, the derived values from thermoanalytical data were compared with literature, related to individual constitutive face mask materials. According to the performed research, it was established that different maximal reaction rate values at various heating rates indicate the complex nature of coronavirus face mask thermo-oxidative degradation, which is stimulated with carbon oxidation reactions and volatile matter (VM) release. By detailed analysis of obtained TGDTG profiles, it was established that process takes place through multiple-step pathways, due to many vigorous radical reactions, causes by polymers degradation. The performed research was done to evaluate the possible utilization of coronavirus waste to energy production and sustainable pandemic environmental risk reduction.

AB  - To achieve sustainable development and mitigate the climate change challenges,  the use of food industry residues is an important part of the modern circular econ-  omy. The residues from the fruit juice production industry are nowadays commonly  used raw materials for producing different value-added products. In order to improve  the energy efficiency aspects of the industry residue treatment, generally, the drying  process as the first step of the whole processing chain should be further analyzed.  Regarding these facts, a comprehensive kinetic study was performed to provide the  detailed mechanisms of moisture removal from the base raw material. The industrial  residues from apple juice production were used for experimental isothermal TG anal-  ysis in the air atmosphere at five different temperatures. Based on experimental data,  different kinetic models were applied to determine the kinetic parameters and dom-  inant conversion functions. The obtained results of activation energy were compared  with literature data and further discussion about the decomposition mechanisms was  provided. The results of this research will be further used for developing the univer-  sal mathematical model of the drying process which could be applied for other sim-  ilar food materials and could provide new data for the energy efficiency improve-  ment of the food residues processing industry.

AB  - The emission control from coal-fired power plants is on a global level in focus last decades due to environmental issues. The emission of nitrogen oxides is recognized among the other pollutants, as the key environmental problem related to energy production by the coal utilization. In this paper, the effect of fuel nitrogen delivery on the NOx precursors (HCN and NH3) during devolatilization processes of selected coal samples (with high content of nitrogen) has been examined. TG-DTG coupled with mass spectrometry (MS) experimental techniques was used for the assessment of nitrogen distribution for HCN and NH3 as intermediate species during coal devolatilization, which directly influences the emission of nitrogen oxides during the combustion process. Further by the establishment, the mass balance of nitrogen together with performed analysis of evolved gases, the distribution of nitrogen between volatiles and char could be also determined. The obtained data for particular coal samples could be exploited for further coal combustion process optimization in regard to NOx emissions, and can be used as the experimentally determined input parameters for mathematical modeling of the coal combustion process, in the large-scale coal-fired power plants.
AB  - Kontrola emisija iz termoelektrana na ugalj je na globalnom nivou u fokusu poslednjih decenija zbog zaštite životne sredine. Emisija azotnih oksida je, pored ostalih zagađivača, prepoznata kao ključni ekološki problem koji se odnosi na proizvodnju energije korišćenjem uglja. U ovom radu je ispitan uticaj raspodela azota iz goriva na prekursore azotnih oksida (HCN i NH3) tokom procesa devolatilizacije, za izabrani uzorak uglja sa visokim sadržajem azota. Eksperimentalne tehnike TG-DTG direktno povezane sa masenom spektrometrijom (MS) korišćene su za procenu raspodele azota iz goriva na HCN i NH3 kao međuvrste tokom procesa devolatilizacije uglja što direktno utiče na emisiju azotnih oksida tokom procesa sagorevanja. Daljom postavkom masenog bilansa azota zajedno sa izvršenom analizom evoluiranih gasova može se utvrditi i raspodela azota između volatila i koksnog ostatka. Dobijeni podaci za pojedine uzorke uglja mogu se koristiti za dalju optimizaciju procesa sagorevanja uglja u pogledu emisije NOx i mogu se koristiti kao eksperimentalno određeni ulazni parametri za matematičko modeliranje procesa sagorevanja uglja u velikim termoelektranama na ugalj

AB  - This study presents the experimental results of the mechanical and thermophysical properties of wood pellet samples important for their utilization in pellet stoves and boilers for heat production. The impact of operational parameters during the production process on a single pelletizer unit for three typical domestic commercial wood pellet samples (PWP110, BWP110, and BWP140) on fuel particle mechanical characteristics and related thermal properties was analyzed. It was concluded that the changes in raw material selection, as well as related operating parameters (extrusion length, i.e., die temperature during production process), have influenced the key mechanical and thermal characteristics of tested commercial wood pellets. The presented results have indicated the existence of a thin solid layer (due to waxes and subsequently lignin coating layer behaviors depending on their glass transition temperatures) on the surface of the BWP140 pellet sample. This layer leads to increasing the thermal resistance in the considered sample which can be explained by decreasing the effective thermal conductivity. Also, the forming of this layer on the surface of the wood pellet sample was caused by the production process (high-temperature impact explained by increasing friction between the die and feedstock during pellets production). It could be related to a lower value of effective thermal conductivity and specific heat capacity for considered (Beech) wood pellet sample.
