A PROCESS FOR HYDROCRACKING A HYDROCARBON DISTILLATE TO A GASOLINE FRACTION BOILING BELOW ABOUT 200*F. AND HAVING A LEADED F-1 OCTANE RATING OF AT LEAST 97, WHICH COMPRISES CONTACTING A HYDROCARBON FEED BOILING WITHIN A RANGE FROM ABOUT 200 TO 450*F. AND HAVING AN AROMATIC CONTENT OF NOT MORE THAN 10 PERCENT BY VOLUME AND A BASIC NITROGEN CONTENT OF LESS THAN 25 P.P.M., ALONG WITH AT LEAST 2000 S.C F. HYDROGEN PER BARREL OF SAID FEED, WITH A CATALYST COMPRISED OF AT LEAST 1% BY WEIGHT OF AT LEAST ONE HYDROGENATING COMPONET SELECTED FROM THE GROUP CONSISTING OF NICKEL SULFIDE AND COBALT SULFIDE, SAID COMPONENT BEING CARRIED ON A SILICEOUS ACTIVE CRACKING SUPPORT, THE CONTACTING OVER THE CATALYST BEING EFFECTED AT PRESSURES OF FROM ABOUT 200 TO 3000 P.S.I.G. AND AT AVERAGE CATALYST TEMPERATURES OF FROM ABOUT 450* TO 730*F. WHEREBY THERE IS OBTAINED A CONVERSION OF THE FEED TO THE AFORESAID GASOLINE FRACTION OF AT LEAST 20% PER PASS OVER THE CATALYST, THERE BEING CONSUMED IN SAID PROCESS AT LEAST 1000 S.C.F. HYDROGEN PER BARREL OF FEED CONVERTED TO PRODUCT BOILING BELOW THE INITIAL BOILING POINT OF THE FEED
