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 fuel-NOx emissions during the conversion of carbon-based feedstock into energy and chemicals are on a global level in focus last decades due to environmental issues. The emission of nitrogen oxides is recognized among the other pollutants, as one of the key environmental problems related to energy production by various types of feedstocks. In this paper, the effect of fuel-based nitrogen delivery on the development of NOx precursors (HCN and NH3) during the devolatilization process of properly selected samples (coal, sawdust, wheat straw, and ground coffee waste) has been examined. TG-DTG thermal analysis techniques, coupled with mass spectrometry (MS) were used for the assessment of nitrogen distribution for HCN and NH3 gases, as intermediate species during feedstocks devolatilization, which directly influences the NOx emission during thermochemical conversion processes (pyrolysis and combustion). The mass balance of nitrogen together with performed EGA (evolved gas analysis), and the distribution of nitrogen between volatiles and formed char were also determined. The obtained data for investigated samples could be exploited for further thermochemical process optimization, in regard to NOx emissions. The presented results could be used as the experimentally determined input parameters for the mathematical modeling of indicated processes, and with further analysis can be transferred to large-scale industrial plant applications.

AB  - Thermal analysis represents a group of techniques that analyse various physical and/or chemical properties of a sample as a function of temperature, during heating or cooling according to a certain temperature program. 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  - This work provides a novel methodology for the comprehensive evolved gas analysisperformed on a lab scale level during the biomass thermal degradation experimental tests.TGA – MS coupling allows accurate correlation between molecular ion peak and fragmentpeaks to the corresponding mass loss rates from DTG curves. Within the proposed semiquantitativeanalysis, MS spectra were interpreted through the comparative analysis ofcompound fragments and of the compound itself, where the single atomic mass unit wasidentified by multiple compounds exhibition [1]. It was shown that by this procedure whichinvolves overlapping multiple curves supervising, the identification of gases in the volatilescomplex scheme becomes more simplified. The simplified scheme for the proposedmethodology with major steps necessary to be performed is presented in Figure 1. By setting up semi-quantitative formulas, easy and reliable calculations of gaseousproducts yield and syngas energy capacities are possible to achieve. The obtained results byproposed methodology for wheat straw sample is given in Table 1.

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  - 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  - Jedan od ciljeva koje je čovečanstvo postavilo do 2050. godine je dekarbonizacija u energetskom sektoru. Iz tog razloga upotreba vodonika kao alternativnog goriva izgleda kao moguće rešenje. Međutim, konvencionalni proces proizvodnje vodonika (elektroliza) sada indirektno čini više od 2% ukupne globalne emisije CO2. Jedan od scenarija za dostizanje postavljenih ciljeva uključuje dekarbonizaciju proizvodnje vodonika, što rezultira zelenim vodonikom. Jedan od načina za proizvodnju zelenog vodonika je moguć putem gasifikacije lignoceluloznih materijala (biomasa kao sirovina) u sintetički gas. Međutim, različiti parametri sirovine utiču na proces termohemijske konverzije, odnosno prinos i sastav sintetičkog gasa. Ovaj rad prezentuje novu semi-kvantitativnu analizu eksperimentalnih podataka dobijenih fundamentalnim eksperimne-talnim tehnikama, termogravimetrijom i masenom spektrometrijom. Prema predloženoj metodologiji na laboratorijskom nivou moguće je proceniti kvalitet sirovine za identifikaciju prinosa i sastava sintetičkog gasa, sa posebnom pažnjom na sadržaj vodonika u sintetičkom gasu. Predstavljeni su eksperimentalni rezultati za dva uzorka biomase i na osnovu izvršene semi-kvantitativne analize procenjena je mogućnostkorišćenja razmatranih sirovina za proizvodnju zelenog vodonika.

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  - 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  - Food wastes are generated massively across global food supply chains. Conventional treatments of food waste (e.g.,landfilling and incineration) could cause environmental, economic and social problems. Valorization of food wasteinto value-added chemicals is a more sustainable and cost-effective option. This paper investigates the slow pyrolysisas an environmentally friendly and efficient way to thermo-chemically conversion of food waste into value-addedproducts. TGA-DTG study of slow pyrolysis of dried Goji berry pulp (GBP) samples was carried out at differentheating rates. To establish pyrolysis mechanism, two kinetic approaches were used for determination of kineticparameters: first, which involves using model-free methods and second, the use of iso-kinetic relationship analysis toidentify the low and high-temperature kinetic regimes during the chemical transformation of the investigated material.It was shown that iso-kinetic temperature (363.79 °C) represents a transition from the low-kinetic regime (enzymatichydrolysis) to the high-kinetic regime (acid hydrolysis), which strongly depends on temperature i.e. applied heatingrate. Significant compensation between kinetic parameters is a consequence of a change in the mechanism ofglucosides’ bond cleavage.

AB  - Despite many advantages of the utilization of biomass as a renewable energy source, certain bottlenecks during biomass plant operation can be identified. Transport and collection of biomass as well as non-uniform material characteristics are issues related to decreasing efficiency of logistics and fuel manipulation which can also cause economic problems with biomass collection, transport, and storage. Since biomass is an especially reactive fuel, this has raised concerns over its safe handling and utilization. Fires, and sometimes explosions, are a risk during all stages of fuel production as well as during handling and utilization of the product. This paper presents a novel method for assessing ignition risk and provides a ranking of relative risk of ignition of biomass fuels. Tests within this method include physical and chemical properties of biomass, thermal analysis measurements, and the calculation procedure steps which were made using characteristic temperatures from thermogravimetry recordings. The results of thermogravimetry analysis were used for determination of tangent slope of the mass loss rate curves in devolatilization zone at considered heating rates for all tested samples. Linear interpolation of the data obtained by tangent slope analysis and used heating rates may provide unique straight line for each sample in the ignition testing. Thermogravimetry index of spontaneous ignition (TGspi) is obtained for all samples based on newly established formula. By varying gradient of linear dependence of self-heating coefficient against reference temperatures, mass and heat transfer limitations for various biomasses were discussed. The proposed method is accurate as well as relatively simple and quick, enabling determination of data necessary for design and application of appropriate measures to reduce fire and explosion hazard related to operation of biomass.

AB  - This paper provides in-depth knowledge about the evolved gas analysis interpretation via newly proposed semi-quantitative approach, arising from thermogravimetric analysis (TGA) – mass spectrometry (MS) coupled measurements, for studying pyrolysis behavior of three kinds of biomass waste materials (spent coffee grounds, beech sawdust and wheat straw). TGA – MS coupling allows accurate correlation between molecular ion peak and fragment peaks to the corresponding mass loss rates from derivative thermogravimetry curves. Within proposed semi-quantitative analysis, MS spectra were interpreted through the comparative analysis of compounds fragments and of the compound itself, where the single atomic mass unit was identified by multiple compounds exhibition. It was shown that by this procedure which involves overlapping multiple curves supervising, the identification of gases in volatiles complex scheme becomes more simplified. By setting up semi-quantitative formulas, easy and reliable calculations of gaseous products yield and syngas energy capacities are possible to achieve. The H2/CO ratio derived from the proposed method for wood waste product (sawdust) is in an excellent agreement with H2/CO ratio for sawdust syngas production, in fuel reactor for biomass gasification and H2 production. © 2021 Elsevier B.V.

AB  - Thermo-analytical characterization of selected biomasses (agricultural waste and wood biomass feedstock) through the pyrolysis process was performed under dynamic conditions. Slow pyrolysis (carbonization) regime (with a heating rate below 50 °C min−1) was selected because it favours the residual solid (bio-carbon/bio-char) in the higher yields (change in the surface area of bio-char with pyrolysis conditions was dependent on the type of biomass feedstock). Comparison of results and discussions related to obtained percentage pyro char yields from thermo-chemical conversion of biomass feedstocks were generated from simultaneous thermal analysis (STA) (TGA-DTG-DTA apparatus). The analysis of gaseous products of pyrolysis was carried out using mass spectrometry (MS) technique. Releasing of the light gaseous compounds (mainly CO, CO2, CH4, and H2 non-condensable gases) was monitored simultaneously with TGA measurements. Discussion related to this issue was performed from the aspect of the syngas production, as well as the versatility of selected biomasses in the gasification process where the various gasifying agent may be in use. © Springer Nature Switzerland AG 2020.

AB  - The combustion reactivity of plane tree seeds biomass feedstock was studied using the thermogravimetry. The effects of atmosphere (O2/Ar) and different oxygen concentrations (O2/Ar = 20:80% and O2/Ar = 50:50%) on the combustion characteristics were investigated. When combustion atmosphere changes from O2/Ar = 50:50% to O2/Ar = 20:80% (reducing oxygen concentrations), the burnout temperature increases by 29.50 °C for tested biomass. Obtained results demonstrate the ease of ignition of investigated lignocellulosic material for O2/Ar = 50:50% ratio compared with O2/Ar = 20:80% ratio, and the actual trend is maintained under the condition when the heating rate increases. The reducing of oxygen concentration strongly influenced the amount of final residue products, particularly at higher heating rates (beyond 10 °C min−1). Kinetic analysis applied to investigated process shows strongly dependencies of both the apparent activation energy (E) and pre-exponential factor (logA) with conversion (α), especially in devolatilization and combustion of volatiles reaction stages. Large variation in E is attributed to existence of multiple parallel reactions. In order to solve this problem, the deconvolution technique that uses Fraser–Suzuki function was applied. It was shown that Fraser–Suzuki function fits successfully kinetic rate curves of entire combustion process, assuming the best selected nth-order reaction model.

AB  - The pyrolysis process of various types of biomass (agricultural and wood by-products) in non-isothermal conditions using simultaneous thermal analyses (STA) was investigated. Devolatilization kinetics was implemented through combined application of model-free methods and DAEM (distributed activation energy model) using Gaussian distribution functions of activation energies. Results obtained were used in the curve prediction of the rate of mass loss against temperature at various heating rates by numerical optimization. The possible calculation of biomass samples behavior under pyrolytic conditions as the summation of their pseudo-components, hemicelluloses, cellulose, and lignin is also explored. The differences between experimental and calculated data are less than 3.20% offering a quality test of applicability of proposed model on the kinetic studies of a wide range of biomass samples. It seems that the most physically realistic model is the decomposition of biomass in three reactions, depending on the composition of the biomass regarding hemicelluloses, cellulose, and lignin. Kinetic model applied here may serve as a starting point to build more complex models capable of describing the thermal behavior of plant materials during thermochemical processing.
