| Abstract: | 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. |
