Prediction of higher heating values (HHVs) and energy yield during torrefaction via kinetics

Energy Procedia, 2019
Torrefaction is a promising process to upgrade biomass and produce solid biofuel. The purpose of this study is to predict the higher heating values (HHVs) of biomass and energy yield during torrefaction. A two-step model and a direct method are adopted to obtain the torrefaction kinetics and the prediction of elemental composition in the present study.
