Abstract

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.
