This patent describes a process for the cracking of a hydrocarbon oil feed having a significant content of at least 0.1 ppm vanadium to lighter oil products. The process consists of contacting the feed under conversion conditions in a conversion zone with a catalyst containing a precipitated metal additive to immobilize vanadium compounds by forming compounds therewith that have melting points above temperatures found in regenerating a coked catalyst; and having catalytic cracking characteristics, coke and vanadium being deposited on the catalyst by the contact; regenerating the coked catalyst in the presence of an oxygen containing gas at a temperature sufficient to remove at least some of the coke, and, recycling the regenerated catalyst to the conversion zone for contact with fresh feed; the metal additive being present on the catalyst in an amount sufficient to immobilize at least a portion of the vanadium compound in the presence of the oxygen containing gas at the catalyst regeneration temperature; wherein the metal additive to immobilize vanadium compounds deposited on the catalyst is selected from the group consisting of Sr, Sc, Y, Nb, and Ta elements, and an element in the actinide series, or a combination of two or more of the elements.
