文章以生物质稻秸为研究对象,利用A spen Plus软件建立了串行流化床生物质合成气费托(Fischer‐T ropsch ,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,采用蛋壳型钴基催化剂,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0.1 MPa ,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2.0 M Pa左右。在此工况下,每kg稻秸可以获得约为0.54 mol的费托合成油。

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 ,synthesis temperature and pressure on the synthesis were ana‐lyzed .T he results are as follow s :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 M Pa is adopted .On the optimal op‐erating conditions ,the maximum FT‐oil yield may reach 0.54 mol per kilogram rice straw .
