摘　　要：为考察生物油超临界乙醇提质方法的能源效率和经济性能,建立了生物质快速热解超临界乙醇提质制取液体燃料工艺流程及其仿真模型.在仿真计算的基础上,对液体燃料生产成本进行计算,将生物质快速热解超临界乙醇提质制取液体燃料与生物质热解催化加氢和纤维素制乙醇方法进行对比,并通过敏感性分析研究了不同因素对液体燃料生产成本的影响.结果表明:液体燃料生产成本为6 052元/t(216元/GJ),略高于生物质热解催化加氢工艺,但明显低于纤维素制乙醇工艺;对液体燃料生产成本影响最大的因素是生物油产率和乙醇价格,提高热解过程中生物油产率和减少提质过程中乙醇消耗均有利于提高系统经济性能.To study the energy efficiency and the economic performance of bio-oil upgrading method in supercritical ethanol, the process and its simulation model for the production of liquid fuels by bio-mass fast pyrolysis and bio-oil upgrading in supercritical ethanol were established. On the base of the simulation, the system energy conversion efficiency and the fuel production cost were calculated and compared with the catalytic hydrogenation of biomass pyrolysis and cellulose-into-ethanol processes for liquid fuels. The effects of different factors on fuel production cost were also researched by the sensitivity analysis. Results show that fuel production cost is 6 052 RMB/t（216 RMB/GJ） slightly higher than that of catalytic hydrogenation process but significantly lower than that of cellulose-intoethanol process. The bio-oil yield during the process of pyrolysis and the ethanol price have the greatest impact on fuel production cost, enhancing bio-oil yield and reducing the consumption of ethanol during the process of bio-oil upgrading can improve economic performance of the system.
