摘　　要：用不同方法制备了几种硫化铁催化剂，研究了其对Ｈ＿２Ｓ分解制取氢气反应的催化性能。用ＴＰＲ、ＸＲＤ、ＴＰＯ、ＤＴＡ及表面积测定等手段对反应前后的催化剂进行了表征。结果表明，以机械混合的超细粒子α－Ｆｅ＿２Ｏ＿３和γ－Ａｌ＿２Ｏ＿３为催化剂的先驱物时，其反应性能最佳。The preparation and catalytic performances for thermochemical decompositionreaction of H_2S to H_2 of several catalysts of iron sulfide were investigated.Before and after re-action,the catalysts were characterized by TPR,XRD,TPO,DTA and surface area measure-ment.The results show that in various catalysts of iron sulfide,the superfine α-Fe_2O_3+Al_2O_3catalyst is the optimum one in reactivity and stability for thermal decomposition reaction ofH_2S to H_2.
