| Summary: | This study developed a mathematical model for the co-torrefaction of low-rank coal and biomass, aiming to predict the final mass of solid produced and temperature distribution within a particle. The Simple Arrhenius and Distributed Energy Activation Model (DAEM) were used as micro-modeling methods to predict kinetics data for mixtures with 20 %, 30 %, and 40 % biomass, achieving regression factors above 0.99. DAEM kinetics data were applied to macro modeling, where temperature distribution inside particles and the final solid mass were analyzed. The model showed 2.5 %–7 % deviations from experimental results, confirming its reliability in predicting co-torrefaction behavior. |
