(1) product description LH-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 bumer, 92-95% it react by two stages clause processes, furthermore to higher than 98% if by three clause reactors.
