A PROCESS FOR THE PREPARATION OF A METAL-DOPED PENTASIL-TYPE ZEOLITE

Abstract The present invention relates to a process for the preparation of a metal-doped pentasil-type zeolite, which comprises the steps of: a) preparing an aqueous precursor mixture comprising a silicon source and an aluminium source, at least one of these sources being doped with a rare earth metal or a transition metal of Groups Vb- VIIIb, Ib, or lib of the Periodic System, and b) thermally treating the precursor mixture preferably at 130-200°C for 3-60 hours, to form a metal-doped pentasil-type zeolite.
