摘要: A torrefaction study using RS (rice straw) and CS (cotton stalk) was carried out to better understand the effects of process conditions different compositions biomass on changes in properties products based RSM (response surface methodology). The comparison energy yield, densification, main parameters were evaluated through a complete analysis products. optimal for highest yield obtained at least severe 210 °C 20min. weight reduction raw after 13–48% 9–50% CS, recovery solid product over 77% 68% CS. heating value torrefied determined be 28.6 MJ/kg. When it comes showed higher degree densification than maximum densified values as 1.48 1.37 which can contribute alleviating transportation storage difficulties. Based statistical analysis, mainly affected by temperature, while condition interaction temperature time.
