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.
Cette invention concerne la préparation d'une composition comprenant un zéolite de type pentasile, qui consiste à : a) traiter hydrothermiquement une suspension aqueuse épaisse comprenant une source d'aluminium, une source de silicium, un matériau d'ensemencement et éventuellement une source de métal divalent, pour former un zéolite de type pentasile et au moins un autre composé, et b) façonner le produit obtenu à l'opération a). Exemples d'au moins un autre composé susmentionné : argile anionique, argile cationique, cogel Si-Al, et (pseudo)boehmite.
