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 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.
