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 an ordinary bumer.92-95% it react by two stages clause processes. Furthermore to higher than 98% if by three clause reactors.
