PSR-31 Sulfur Recovery Catalyst

1.universal catalyst for sulfur recovery in acid gases 2.pore volume:0.45ml/g 3.surface area:320m2/g 4.bulk density:0.68~0.72

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.
