Abstract

AbstractEffects of CO2 on the yield and fuel properties of the solid product obtained from wet torrefaction of biomass were experimentally investigated. Norwegian forest residues were used as feedstock. CO2 and N2 were employed as purge gas, separately. The results show that, compared with wet torrefaction in N2, the process in CO2 is taking place faster, producing 4.6-6.0% less solid product with lower heating value in identical condition. A reduction of 6.5kWh/t in SGE and an increase of up to 1.4% in EMC were observed for the solid product obtained from WT in CO2 compared with that in N2. In addition, CO2 enhances the capacity of wet torrefaction to remove ash elements from solid biomass fuels.
