摘要：Biomass to oil (BTO) processes consist of units of biomass collection,biomass fast pyrolysis , bio-oil gasification , water gas shift , acid gas removal , CO2 capture and storage , Fischer-Tropsch (FT) synthesis,syncrude refining,and tail gas treatment. The combustion of process tail gas,natural gas,or other fuels in boilers and gas turbines is the source of steam and power generation to satisfy process heating,cooling,electricity,and shaft power demands in the utility system. The process tail gas including FT synthesis tail gas and syncruderefining tail gas,contains CO,H2, CH4,C2H6 and so on. The process tail gas can be used as utility system fuel for energy and power generation. It also can be recycled for process synthesis by reforming operation,and the utility system need to add fuels. In this paper,barley straw is taken as the biomass feed to make the transport fuel. Based on ASPEN simulation of BTO processes and utility systems,the influence of process operating parameters and tail gas treating methods on the process products and utility fuel selection are analyzed to obtain the optimal design of BTO processes and utility system with the maximum plant gross profit.
