Hydrocarbon conversion process and catalyst

Claim 1

A PROCESS FOR CONVERTING A NITROGEN-CONTAINING HYDROCARBON FEED SELECTED FROM THE GROUP CONSISTING OF PETROLEUM DISTILLATES BOILING FROM 500* TO 1100*F. AND PETROLEUM RESIDUA BOILING ABOVE 500*F. WHICH COMPRISES CONTACTING SAID FEED IN A FIRST STAGE IN THE PRESENCE OF FROM 1000 TO 10,000 S.C.F. OF HYDROGEN PER BARREL OF SAID FEED AND IN THE PRESENCE OF A CATALYST COMPRISING AT LEAST ONE HYDROGENATING COMPONENT SELECTED FROM THE GROUP CONSISTING OF GROUP VI METALS AND COMPOUNDS THEREOF AND AT LEAST ONE HYDROGENATING COMPONENT SELECTED FROM THE GROUP VIII METALS AND COMPOUNDS THEREOF AND A SILICA-MAGNESIA SUPPORT AT A TEMPERATURE OF FROM 500* TO 950*F., A HYDROGEN PARTIAL PRESSURE FROM 1000 TO 2500 P.S.I.G. AND AN LHSV OF FROM 0.1 TO 4.0, RECOVERING A GASOLINE PRODUCT FROM SAID FIRST STAGE, AND CATALYTICALLY CRACKING IN A SECOND STAGE IN THE PRESENCE OF A CONVENTIONAL CATALYTIC CRACKING CATALYST AT LEAST A SUBSTANTIAL PORTION OF THE LIQUID EFFLUENT FROM SAID FIRST STAGE, TO PRODUCE ADDITIONAL QUANTITIES OF GASOLINE.
