Al2O3-TiO2 based multi-function sulfur recovery catalyst

Multi-function Sulfur Recovery Catalyst 

Al2O3-TiO2 based sulfur recovery catalyst characters

LSS-981 is a kind of Al2O3-TiO2 based sulfur recovery catalyst with alkaline and iron promoters. Its comprehensive performances and technical indexes have reached the international advanced level.

  • High Claus activity, hydrolysis activity and O2 scavenging property.
  • Good sulfation resistance and resistance to carbon formation.
  • High mechnical strength, stable structure and good activity stability.
  • High resistance to process fluctuations and long service life.


Al2O3-TiO2 based sulfur recovery catalyst characters Applications and operating conditions

Suitable for Claus sulfur recovery in petrochemical and coal chemical industry, it can be used in any Claus reactor loaded full bed or in combination with other catalysts of different types or functions. It has a good sulfation resistance and resistance to carbon formation, and it is not sensitive to the fluctuations of hydrocarbon content in the acid gases. Used in the primary rector, it can promote organic sulfur hydrolysis rate, in secondary and tertiary reactors, it can increase the total sulfur conversion.
