activated alumina

1. Product DescriptionPSR 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. 2.
