To improve the hydrogen yield in biomass gasification, the addition of biogas for co-feeding with biomass in gasification was proposed in this work. The gasification model developed in Aspen Plus software was validated with experimental data. The performance of biomass gasification with biogas co-feeding using steam as a gasifying agent was investigated. The effect of the steam-to-fuel ratio on the gasification of mixed biomass and biogas was studied. The results show that the simulation results of biomass gasification were consistent with experimental data. Biomass gasification with biogas co-feeding can raise the amount of hydrogen and carbon monoxide in gas products by 22.12% and 18.44%, respectively. Moreover, the increase in the steam-to-fuel ratio enhances hydrogen in syngas. However, the system efficiency decreases with increasing steam-to-fuel ratio.

摘要

To improve the hydrogen yield in biomass gasification, the addition of biogas for co-feeding with biomass in gasification was proposed in this work. The gasification model developed in Aspen Plus software was validated with experimental data. The performance of biomass gasification with biogas co-feeding using steam as a gasifying agent was investigated. The effect of the steam-to-fuel ratio on the gasification of mixed biomass and biogas was studied. The results show that the simulation results of biomass gasification were consistent with experimental data. Biomass gasification with biogas co-feeding can raise the amount of hydrogen and carbon monoxide in gas products by 22.12% and 18.44%, respectively. Moreover, the increase in the steam-to-fuel ratio enhances hydrogen in syngas. However, the system efficiency decreases with increasing steam-to-fuel ratio.
