The objective of this study was to examine the torrefaction process of three lignocellulose biomasses (rice husks, coffee shell, and wood) produced in Vietnam. Three different torrefaction temperatures ranging from 200oC to 300oC and three residence times of 20, 40, and 60 min were considered. The result showed that temperature had a higher effect on torrefaction process of biomass than residence time. Based on the findings of this study, a residence of 40 min could be suggested for an effective and proper torrefaction process to recycle the agricultural biomass and wood at 300oC. The torrefied products become fuel sources which can be applied to replace with fossil fuels.
