摘　　要：以流化床煤气化工况为参数，采用热力学数据，对石灰石（白云石）在煤气化过程中的固硫机理进行了分析。结果表明，ＣａＯ和ＣａＣＯ＿３均具有固硫能力；适量石灰石的添加，对灰渣及气化效率没有明显影响。In this paper,during coal gasification the mechanism of limestone capturing and removing sulfur in fluidized-bed has been studied by the thermodynamics criterion, using parameters of operating condition in the gasification.The results showed that:CaO and CaCO_3 have the function of desulphurization,FeO and Na_2O in the limestone have the possibility of desulphurization, however,MgO,K_2O and Al_2O_3 haven't desulphrization effect.
