Activated Alumina as Sulfur Recovery Catalyst

Activated Alumina as Sulfur Recovery Catalyst

It produces large amounts of H2S gas in the process of natural gas purification and sulfur crude oil processing, in order to protect the environment and recovery of sulfur, people use claus technology processing H2S sour gas, and activated alumina sulfur recovery catalysts play an important role in this process.

Activated alumina sulfur recovery catalyst has very large pore structure, pore radius larger than 700? are more than 70% of the total pore volume. This macroporous structure can reduce the diffusion resistance, make the reactant diffusing into catalyst internal quickly, and let generation of sulfur spread out from catalyst internal quickly, so activated alumina sulfur recovery catalyst compared with ordinary alumina catalyst has higher catalytic efficiency and longer service life.

Activated alumina sulfur recovery catalyst has large porosity ratio, high specific surface area, good thermal stability, high strength, small abrasion ratio, resistance to sulfate poisoning, high organic sulfur hydrolysis rate, long service life.

Titanium Dioxide Sulfur Recovery Catalyst is a kind of TiO2 / Al2O3 auxiliary type sulfur recovery catalyst, through the special impregnated preparation technology loading active components TiO2on the activated alumina carrier, thus it has higher activity of hydrolysis reaction to the organic sulfide such as COS and CS2.

TiO2 sulfur recovery catalyst is mainly used for catalysing hydrogen sulfide and sulfur dioxide chemical reaction generated elemental sulfur in the claus sulfur recovery process, processing all kinds of acid gas containing H2S. Can be used in any level converter used of sulfur recovery device, also can fill in the lower part of the first reactor for the hydrolysis reaction of organic sulfide COS/CS2.
