Abstract

Based on the route of biomass gasification with Fischer-Tropsch synthesis to produce liquid fuel, and using Aspen Plus software to establish the simulation model of the process, the influence of operation parameters of each unit on aviation kerosene output was studied. The energy usage ratio of the whole system under optimal conditions was analyzed. The results reveal that the impact of biomass gasification unit on jet fuel production mainly come from the material ratio of H₂ to CO（H₂/CO）, the optimal gasification temperature is 750 ℃, pressure is 0.1 MPa, mass ratio of steam to biomass（S/B）is about 0.5. The fuel production and energy efficiency is improved with increasing FT synthesis temperature and pressure, the unit’s optimal Fischer-Tropsch synthesis temperature is 230 ℃,pressure is 2.5 MPa. Under the optimal condition, when the revenue exergy only contains jet fuel exergy, the total exergy efficiency is 49.67%. When whole by-products exergy are included, the total exergy efficiency is 59.48%.
