Abstract
Abstract A method of preparing a composition comprising a crystalline zeolite and a porous matrix material which comprises coating at least a portion of the surface of at least one of the components selected from the group consisting of said zeolite and said porous matrix material with a solid or liquid coating material which is substantially retained during any subsequent processing steps prior to its positive intentional removal, which occurs after the compositing step, intimately compositing said zeolite with said matrix material and removing said coating material; the composition prepared therefrom and hydrocarbon conversion employing the composition as a catalyst.
