White spherical particles, insoluble in water and organic solvents, soluble in strong acid and alkali solution, moisture absorption in the air, water absorption does not swell and crack. It is an improved sulfur recovery catalyst. The Claus reaction intrinsic activity and sulfate poisoning resistance of the AL203-based catalyst, as well as the activity after "mild aging" treatment and "severe aging" treatment, are better than those of the AL2O3 catalyst used in industry.

This product is suitable for Claus sulfur recovery process in refineries containing H2S acid gas, natural gas purification and desulfurization plants, city gas plants, petrochemical plants and chemical plants.
