XR401 alumina titania is a promoted catalyst than XR102 sulfur recovery activated alumina, and promoted activated alumina. It retards the conversion of the sulfide species to sulfur.


XR-401 alumina titania catalyst is a TiO2-Al2O3 catalyst, which surface coated with nanoparticles TiO2. The promoter on XR401 activated alumina retards the conversion of the sulfide species to sulfur.  The unabated reaction can cause sulfation (sulfur layering) on the surface of the catalyst.  Promoted alumina has also shown improved COS (carbonyl sulfide) decomposition over time. Alumina titaniua could be used as titania alumina supports.


Claus units are designed to convert H2S and SO2 to elemental sulfur.  However, the catalyst must also have good activity for conversion of CS2 (carbon disulfide) and COS (carbonyl sulfide).  CS2 is a by-product that forms in the reaction furnace from impurities in the acid gas.  COS is formed by the presence of CO2 and CO.  CS2 is harder to convert, as high temperatures are required for the reaction rates.

Claus conversion occurs very quickly in all converter beds, but is incomplete because of equilibrium limitations.  Low temperatures in adsorber beds favor higher conversion.  Lower inlet temperatures are used in successive adsorber reactors to maximize sulfur make.

FAQ:

Q: What application is alumina titania?

A: It is promoted activated alumina. It could be used as claus catalyst, organic sulfur hydrolyst, titania alumina supports.

Q: What is titania content in alumina titania catalyst?

A: It is about 4~8%. Below 4% or higher 8% is ok. We could do as your required data.
