Claim 1
Independent Claim
85 words
AN IMPROVED HYDROGENATING CATALYTIC COMPOSITION PREPARED BY DEPOSITING ON AN ACID TYPE CARRIER FROM 10% TO 25% OF A METAL SULFIDE SELECTED FROM THE GROUP CONSISTING OF IRON SULFIDE, COBALT SULFIDE, NICKEL SULFIDE, MOLYBDENUM SULFIDE CHROMIUM SULFIDE, TUNGSTEN SULFIDE, AND VANADIUM SULFIDE, AND TREATING THE RESULTING COMPOSITION UNDER NON-HYDROGENATING CONDITIONS WITH AN ORGANIC NITROGENOUS BASE HAVING FROM 4 TO 16 CARBON ATOMS PER MOLECULE FOR A TIME SUFFICIENT TO CHEMISORB SAID BASE THEREON IN AN AMOUNT EFFECTIVE TO INCREASE HYDROGENATING ACTIVITY OF SAID RESULTING COMPOSITION.
