Abstract
A process for the preparation of a composition comprising a pentasil-type zeolite, which process comprises the following steps: a) hydrothermally treating an aqueous slurry comprising an aluminium source, a silicon source, a seeding material, and optionally a divalent metal source, thereby forming a pentasil-type zeolite and at least one other compound, and b) shaping the product of step a). Examples of the at least one other compound are anionic clay, cationic clay, Si—Al cogel, and (pseudo)boehmite.
