PSR Sulfur Recovery Catalyst is used to treat with the acid gases containing H2S for the sake of recovery sulfur element and environmental protection in oil refinery, chemical factory, iron & steel plant and natural gas treatment processes. The conversion of sulfur can reach to 65-75% in a ordinary burner, 92-96% in two stages Claus process, 98% in tree stages Claus process, furthermore to high than 99.8% if Claus tail gas treats with Reduction-Adsorption process.
