A PROCESS FOR THE CONVERSION OF CARBONYL SULFIDE IN A GAS COMPOSITION CONTAINING A SUBSTANTIAL PROPORTION OF NON-ACETYLENIC, NORMALLY GASEOUS, UNSATURATED HYDROCARBONS WHEREBY THE CARBONYL SULFIDE IS SUBSTANTIALLY COMPLETELY CONVERTED WITHOUT APPRECIABLE LOSS OF SAID UNSATURATED HYDROCARBONS, WHICH COMPRISES THE STEP OF PASSING SAID GAS COMPOSITION, SATURATED WITH WATER VAPOR AT ATMOSPHERIC TEMPERATURE AND ATA A PRESSURE ON THE RANGE OF FROM ABOUT 1 TO 40 ATMOSPHERES, WITH HYDROGEN AT A TEMPERATURE IN THE RANGE OF ABOUT 350* TO ABOUT 650*F. OVER A CATALYST COMPRISING A METALLIC CATALYTICALLY ACTIVE CONSTITUENT FOR CONVERTING SAID CARBONYL SULFIDE WHICH IS INACTIVE TOWARDS SAID UNSATURATED HYDROCARBONS, SAID CONSTITUENT BEING SELECTED FROM THE GROUP CONSISTING OF THE OXIDES AND SLUFIDES OF COPPER AND IRON BEING PRESENT IN A CONCENTRATION BY WEIGHT OF FROM 2 TO 10% TOGETHER WITH CHROMIUM OXIDE IN A CONCENTRATION BY WEIGHT OF FROM 2 TO 15% ON A CARRIER HAVING A SURFACE AREA IN THE RANGE OF FROM 100 TO 600 M.2/GM.
