英文摘要	Fe2O3/attapulgite desulfurizer was prepared by impregnation, and was regenerated by use of heat air method. The desulfurization test from a gas containing 100 vol% H2S was carried out over attapulgite supported Fe2O3 in a fixed-bed system at atmospheric pressure and room. The effects of the chemical nature of Fe2O3 on desulfurization capacity were studied. Materials before and after the desulfurization test were characterized using FTIR and XRD. Materials after the regeneration test were characterized using XRD. The characterization results suggest that modification process does not change the structure of attapulgite. Iron species disperses inside channels and the outside surface in the crystalline phase of iron oxide. The material with iron oxide content of 40.0 wt% presented highest H2S uptake capacity. The deactivated that Fe2O3/attapulgite desulfurizer was regenerated 0.8L/min hot air in 323k, the regeneration efficiency reached 81.22%, by 4 times after regeneration can reach 51.9%.
