Process for the preparation of doped pentasil-type zeolites using doped faujasite seeds

Abstract

Process for the preparation of doped pentasil-type zeolite, which process comprises the steps of: a) preparing an aqueous precursor mixture comprising a silicon source, an aluminum source, doped faujasite seeds, and another type of seeding material, and b) thermally treating the precursor mixture to form a doped pentasil-type zeolite. This process results in doped pentasil-type zeolites in a shorter crystallization time compared to prior art processes.
