摘要:
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 aluminium 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 crystallisation time compared to prior art processes.
摘要:
The invention comprises a catalyst composition comprising a pentasil-type zeolite, one or more solid acidic promoters and optionally a filler and/or binder, methods for making the catalyst composition and a process for using the catalyst in the manufacture of olefins.
