摘　　要：利用热天平测试了ＣＯ、Ｈ２还原饱和脱硫剂微孔内Ｆｅ２（ＳＯ４）３的起始反应温度及还原速率，用Ｘ射线衍射法分析了反应中间产物及最终产物．实验结果表明，脱硫剂还原法再生的反应温度较传统热分解法低约２００℃，ＣＯ作再生脱硫剂的还原气体优于Ｈ２，ＣＯ还原脱硫剂内Ｆｅ２（ＳＯ４）３的反应级数为０．８７，活化能为１４２．９ｋＪ／ｍｏｌ．The starting temperatures of Fe 2(SO 4) 3 and Fe 2(SO 4) 3 in the pore of desulfurizer were measured by TGA. The effects of temperature and reduction gas concentration on product were examined. The reduction intermediate and the products were identified by X ray diffraction analysis. CO as reduction gas in regeneration is superior to H 2. The reaction temperature of the reduction method is lower than that of thermal decomposition method. The reaction of reduction regeneration mothod is exothermal and irreversible.
