This invention relates to a catalyst suitable for use in a fluid catalytic process and a method of using the catalyst on hydrocarbons containing one or more poison metal of vanadium or nickel to convert the hydrocarbons to lower boiling fractions. The catalyst contains a particulate and substantially water-insoluble strontium compound (in addition to a conventional zeolite and catalyst matrix) which reacts with and traps the metal poison to preserve the structure of the zeolite and, in addition, lowers the coke make and hydrogen production.

A process for converting a hydrocarbon oil containing at least one vanadium-containing compound, nickel-containing compound, or mixture thereof to lower boiling hydrocarbon products which comprises contacting the oil at conversion conditions with a cracking catalyst containing (a) a zeolitic material; (b) a matrix material; and (c) strontium carbonate dispersed in the matrix as discrete particles, wherein strontium carbonate is present in an amount sufficient to form a product having a melting point greater than about 670°C. when the carbonate is reacted with the vanadium-containing compound, nickel-containing compound, or mixture thereof, at fluid catalytic cracking regenerator temperatures.
