A PROCESS FOR REMOVING NONHYDROCARBONS FROM MIXTURES THEREOF WITH A PETROLEUM FRACTION AND FOR LOWERING THE BOILING POINTS OF A PORTION OF THE PETROLEUM FRACTION WHICH COMPRISES CONTACTING A PETROLEUM FRACTION SELECTED FROM THE GROUP CONSISTING OF GAS OILS AND PETROLEUM RESIDUES CONTAINING NONHYDROCARBONS, AT A TEMPERATURE OF FROM ABOUT 550*F. TO 900*F., A PRESSURE OF FROM ABOUT 1000 TO 2500 P.S.I.G. AND A SPACE RATE OF FROM 0.3 TO 5, AND IN THE PRESENCE OF ADDED HYDROGEN, WITH A CATALYST CONSISTING ESSENTIALLY OF COBALT MOLYBDATE IN AMOUNT TO PROVIDE FROM 5% TO 20% BY WEIGHT OF MOLYBDENUM CALCULATED AS MOLYBDIC OXIDE AND FROM 0.53% TO 10.5% BY WEIGHT OF COBALT CALCULATED AS COBALT OXIDE, FROM 0.2% TO 5% BY WEIGHT OF A PROMOTER SELECTED FROM THE GROUP CONSISTING OF ZINC OXIDE AND CADMIUM OXIDE, AND THE BALANCE ALUMINA.
