Desulphurizing catalyst is a kind of γ-Al2O3. It takes shape of ball granule with many capillary holes passages inside. The surfaces of those passages are good activity. It has high crush proof intensity, strong resistance to abrasion and good duration.  It is much better than natural bauxite catalysts. The product is applicable to sulphur recovery process of refineries with the acid gas H2S, natural gas purifying and desulphurizing plants, urban gas works petrochemical plants and chemical works.
