PROCESS FOR REDUCING TOTAL SULPHUR CONTENT IN GASES CONTAINING HYDROGEN SULPHIDE AND OTHER SULPHUR COMPONENTS

摘要

Process for reducing the total sulphur content of a gas containing hydrogen sulphide and other sulphur components, which process comprises: (a) contacting the gas with a reducing gas in the presence of a hydrogenation catalyst comprising at least one metal component selected from Groups VIB and VIII supported on a carrier comprising amorphous silica-alumina, (b) contacting at least part of the gas obtained from step (a) with a hydrolysis catalyst capable of catalysing the hydrolysis of carbonyl sulphide to form hydrogen sulphide, and (c) removing hydrogen sulphide from the gas obtained from step (b), thus obtaining a product gas having a reduced total sulphur content.
