Claim 1
Independent Claim
127 words
THE METHOD OF PREPARING A HYDROCARBON PURIFICATION CATALYST, HAVING HYDROGENATION PROPENSITIES, WHICH COMPRISES FORMING AN ALUMINA-SILICA CARRIER MATERIAL CONTAINING FROM ABOUT 10% TO ABOUT 25% BY WEIGHT OF SILICA, COMBINING THEREWITH FROM ABOUT 5% TO ABOUT 10% BY WEIGHT OF MOLYBEDENUM AND FROM ABOUT 1% TO ABOUT 5% BY WEIGHT OF NICKEL, OXIDIZING THE RESULTING MIXTURE TO FORM THE OXIDES OF NICKEL AND MOLYBDENUM, THEREAFTER SULFIDING THE OXIDIZED COMPOSITE OVER A TEMPERATURE RANGE INCREASING FROM ABOUT 80*F. TO ABOUT 800*F. WITH HYDROGEN SULFIDE IN A SUBSTANTIALLY NON-REDUCING ATMOSPHERE, AND MAINTAINING THE THUS-SULFIDED HYDROCARBON PURIFICATION CATALYST UNDER A POSITIVE HUDROGEN SULFIDE PRESSURE OF ABOUT 5 TO 15 POUNDS PER SQUARE INCH WHILE THE CATALYST IS BEING COOLED FROM THE HIGHEST SULFIDING TEMPERATURE TO A TEMPERATURE BELOW ABOUT 300*F.
