摘　　要：为研究生物质在等离子体喷动—流化床中的热解影响因素和热解产气成分,文中基于ASPEN PLUS通用化工流程模拟软件,采用花生壳作为生物质原料,氧气作为气化剂,对生物质在等离子体喷动—流化床中的热解气化过程进行模拟,考察了3个重要影响因素(热解温度、当量比ER、气化剂温度)对气化结果的影响。结果表明:氧气气化花生壳的最佳操作条件是热解温度1 000℃、当量比ER=0.25、气化剂温度600℃,此时能得到较高的气化效率和气化产率。To research the pyrolysis factors and syngas composition of biomass in plasma spouted-fluidized bed, the simulation of biomass gasification process in plasma spouted-fluidized bed was car-ried out by using ASPEN PLUS, general chemical process simulation software. The peanut shells were used as raw biomass and oxygen was used as the gasification agent. From the simulation analysis, the effect of pyrolysis temperature, equivalence ratio （ER） and gasification agent temperature on the gasification syngas were studied. The results showed that： the optimal operating condition forpeanut shells gasification is as follows： pyrolysis temperature 1000℃, ER=0. 25, gasification agent temperature 600℃. Under this condition, the higher gasification efficiency and yield can be ob-tained.
