BR-102B Sulfur-Sulfur Recovery Catalyst is a white spherical particle, insoluble in water and organic solvents, soluble in strong acid and alkali solutions. It absorbs moisture in the air, but does not swell or crack upon absorbing water. It is an improved sulfur-sulfur recovery catalyst.

The BR-102B sulfur sulfonation recovery catalyst, based on AL2O3, exhibits superior Claus reaction activity and resistance to sulfate poisoning compared to the commonly used industrial AL2O3 catalysts. Additionally, the catalysts treated with "mild aging" and "severe aging" processes demonstrate enhanced activity and stability.

BR-102B Sulfur-Sulfur Recovery Catalyst is suitable for refineries with H2S acidic gases, natural gas purification desulfurization plants, city gas plants, and sulfur-sulfur recovery processes in petrochemical and chemical plants.
