Thermogravimetric Evaluation for the Pyrolysis Process of Pellets Produced from Quinoa and Amaranth Harvest Residues

In this study, the combustion properties of pellets produced from quinoa (C3 plant) and amaranth (C4 harvest residues were evaluated by Thermogravimetric Analysis (TGA) Differential Thermogravimetry (DTG) methods. Pelletizing was carried out at 25% moisture content a material temperature 70 °C. 7.5% molasses used as adhesive. The heated 25 °C to 1000 in thermal analyzer tracking rate 10 min-1 N2 gas environment. mass loss occurring range recorded simultaneously expressed thermograms. Combustion stages are observed peak DTG curve these peaks represent losses stages. According analysis results, highest evaporation zone water plant 2.12% 96.65 °C, 2.34% 101.7 However, next step, decreased both pellets. At stage analysis, completely evaporated 12.43% 13.38% amaranth, according initial mass. With increase volatile matter output, increased again, rates realized 6.42% 4.96%, respectively, 320 for 315 amaranth. rate-determining kinetics coal biomass is semi-coke stage. stage, lowest (0.89%) occurred pellet samples. TGA results showed that there no significant differences between pellets, their behaviors generally close each other.
