中文摘要：

文章以生物质稻秸为研究对象，利用AspenPlus软件建立了串行流化床生物质合成气费托（Fischer-Tropsch，FT）合成的模型，研究了不同反应条件包括气化温度、气化压力、气化过程水蒸气与生物质的比率（m（S）／m（B））、合成气中n（H2）／n（CO）、合成温度以及合成压力对合成工艺的影响。结果表明．采用蛋壳型钻基催化剂，对于制费托合成油为目的的串行流化床生物质气化系统，用于费托合成的适宜工况条件为：建议气化温度850℃左右，气化压力0．1MPa．m（S）／m（B）约为0．4，合成气中n（H2）／n（CO）保持在2．0～2．1之间．合成反应温度取220℃为佳，反应压力选取2．0MPa左右。在此工况下．每kg稻秸可以获得约为0．54mol的费托合成油。

英文摘要：

Taking the rice straw as the research object, simulation of Fischer-Tropsch（FT） synthesis from biomass gasification in interconnected fluidized beds was carried out using Aspen Plus software. Effects of operating parameters including gasification temperature and pressure, steam/biomass ratio （m （S）/m （B））, n （ H2 ）/n （CO） ratio, synl hesis temperal ure and pressure on the synthesis were ana- lyzed. The results are as follows, the gasification temperature and pressure are suggested to be re- spectively controlled at about 850 ℃ and 0.1 MPa, and the m（S）/m（B） ratio of 0.4 operates better in the interconnected fluidized beds biomass gasification system with the purpose of FT-oil production in the case of eggshell cobalt-based catalysis. Furthermore, the gasification pressure of ambient pressure and the n（H2）/n（CO） ratio of 2.0-2.1 are proposed to be controlled. The synthesis temperature is suggested to be controlled at about 220℃ and the pressure of 2.0 MPa is adopted. On the optimal op crating conditions, the maximum FT oil yield may reach 0. 54 tool per kilogram rice straw.
