Abstract
A composition for passivating metal contaminants in catalytic cracking of hydrocarbons includes a non-layered, ultra-large pore crystalline material with at least one peak at a position greater than about 18 Angstrom Units d-spacing with a relative intensity of 100, and a benzene adsorption capacity of greater than about 15 grams benzene per 100 grams anhydrous crystal at 50 torr and 25.degree. C., and a metal passivator incorporated within the crystalline material. A method for passivating contaminating metals uses the composition during catalytic cracking as an additive or as a component of the catalyst.
