中文摘要：
生物质制油过程可分为生物质收集、生物质快速热解、生物油气化、水汽变换、酸性气体净化和二氧化碳捕集、费托（FT）合成和合成原油提炼，以及尾气处理等部分。公用工程系统通过燃料燃烧产生蒸汽、发电、做功，以满足生产过程所需的蒸汽、水、电、功等。公用工程系统燃料为生产过程尾气，外购天然气或其他燃料。生产过程尾气主要包括费托合成过程和合成原油提炼过程尾气，其主要成分为CO、H2、CH4、C2H6、C3H8。生产过程尾气既可以作为公用工程系统燃料，也可以通过重整操作回收其有效组分CO和H2在生产系统循环利用，但公用工程系统需补充外购燃料。本研究以麦秆为生物质原料，基于生产过程和公用工程系统ASPEN模拟，分析生产过程操作参数和尾气处理方式对生产过程产品产量，公用工程系统燃料选择的影响，根据年总收益最大化确定最优的麦秆制油过程和公用工程系统设计。
英文摘要：
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.
