A METHOD FOR PREPARING GASOLINE WHICH COMPRISES CONTACTING A HYDROCARBON CRACKING FEEDSTOCK BOILING ABOVE THE GASOLINE RANGE AND CONTAINING AT LEAST ABOUT 1 P.P.M. NICKEL AND AT LEAST ABOUT 1 P.P.M. VANADIUM BY INCLUDING IN SAID FEEDSTOCK THE RESIDUAL PRODUCT OBTAINED AS HEREAFTER SET FORTH, WITH A SOLID CRACKING CATALYST UNER CRACKING CONDITIONS TO PRODUCE GASOLINE, REMOVING FROM THE CRACKING SYSTEM CATALYST CONTAMINATED WITH METAL CONTAMINANT, THE REMOVED CATALYST CONTAINING AT LEAST ABOUT 50 P.P.M. NICKEL AND AT LEAST ABOUT 50 P.P.M. VANADIUM, DEMETALLIZING THE CATALYST TO REMOVE AT LEAST 50% OF THE NICKEL AND AT LEAST 15% OF THE VANADIUM FROM THE CATALYST, RETURNING THE CATALYST TO SAID CRACKING SYSTEM AND RECOVERING GASOLINE PRODUCIT FROMSAID CRACKING; SAID FEEDSTOCK CONTAINING THE RESIDUAL PRODUCT OBTAINED BY TREATING A MINERAL OIL HYDROCARBON BOILING ABOVE ABOUT 650*F. AND CONTAINING AT LEAST ABOUT 5 P.P.M. NICKEL AND AT LEAST ABOUT 5 P.P.M.
