A PROCESS FOR HYDROCRACKING A MINERAL OIL REEDSTOCK IN THE OPTIMUM HYDROCRACKING TEMPERATURE RANGE OF ABOUT 680-780*F. TO OBTAIN A RELATIVELY HIGH-OCTANE GASOLINE WITH A MINIMUM PRODUCTION OF LIGHT HYDROCARBON GASES, SAID FEEDSTOCK BOILING ABOVE THE GASOLINE RANGE AND CONTAINING AT LEAST ABOUT 0.3% BY WEIGHT OF ORGANIC NITROGEN, WHICH COMPRISES: (1) CONTACTING SAID FEEDSTOCK PLUS ADDED HYDROGEN WITH A HYDROFINING CATALYST AT ELEVATED TEMPERATURES AND PRESSURES IN A FIRST HYDROFINING ZONE AND CONTROLLING THE SEVERITY OF HYDROFINING SO AS TO (A) EFFECT ABOUT 30-90% DENITROGENATION OF SAID FEEDSTOCK, AND (B) LEAVE IN SAID FEEDSTOCK A REMAINING AMOUNT OF ORGANIC NITROGEN CALCULATED TO YIELD IN STEP (3) AN AMOUNT OF AMMONIA SUFFICIENT TO CONTROL THE HYDROCRACKING TEMPERATURE IN STEP (4) WITHIN THE LIMITS OF ABOUT 680-780*F., SAID REMAINING AMOUNT OF ORGANIC NITROGEN BEING BETWEEN ABOUT 0.03 AND 0.3 WEIGHT PERCENT; (2) TREATING THE EFFLUENT FROM SAID FIRST HYDROFINING ZONE TO SEPARATE AMMONIA THEREFROM AND TO RECOVER A PARTIALLY REFINED OIL; (3) CONTACTING SAID PARTIALLY REFINED OIL PLUS ADDED HYDROGEN WITH A HYDROFINING CATALYST COMPRISING A GROUP VI-B METAL OXIDE AND/OR SULFIDE PLUS A GROUP VIII METAL OXIDE AND/OR SULFIDE AT ELEVATED TEMPERA-
