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  - The pyrolysis process of two low-rank coals (lignite Kostolac and Kolubara), and two wastematerials (spent coffee ground and tyre rubber granulate) as well as their blends, have beenexamined by preliminary thermogravimetric analysis. Thermal decomposition experiments wereperformed in an N2 atmosphere on raw (pyrolysis) and blend (co-pyrolysis) samples at heatingrates of 10, 15, and 20 K min-1. The lignite-waste blend was created in the following masspercentage ratios 90:10, 80:20, and 70:30. Based on obtained experimental data, the stronginteractions were identified between the examined lignite and waste materials during copyrolysis,indicating the presence of a positive synergistic effect. The characteristics of the rawwaste sample and the heating rate were recognized as two key parameters that influenced thesynergy result with lignite sample, in lignite-spent coffee ground blends. For lignite-waste rubbergranulate blends, the blending ratio is critical for beneficial synergistic effect (ratios of wasterubber granulate with lignite less than 30% are preferred). The probable synergistic mechanismswere further explained using performed kinetic analysis by varying the effective activation energywith temperature and conversion. In addition, the influence of micro-scale conditioncharacteristics such as heating rate (as the experimental regulatory factor) on the magnituderesponse of synergistic effect during co-pyrolysis was also investigated in this work.

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
