    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, andb) 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.

    Abstract: The present invention provides new compositions of matter, referred to as quasi-crystalline carboxylates (QCCs), their preparation and use. The materials comprise a quasi-crystalline hydrated magnesium-aluminium hydroxy carboxylate and are characterised by the presence of at least a strong reflection in the powder X-ray diffraction pattern at a basal spacing in the range of 5 to 15 Å. The invention further relates to a process for preparing the QCCs, Mg—Al solid solutions and anionic clays under acidic conditions. The QCC is prepared by aging an acidic mixture of a magnesium carboxylate and an aluminium source. Calcination of the QCC results in a Mg—Al solid solution; rehydration of this solid solution gives an anionic clay.

    Abstract: A process for preparing molecular sieves of type Y faujasite structure is described, as well as pre-shaped bodies of faujasite structure type Y molecular sieves. The process comprises preparing a precursor gel from a source of silica-alumina or a source of alumina and a source of silica with a template agent at a SiO2/Al2O3 greater than 7 and suitable for forming a type Y zeolite, drying the precursor gel and contacting the dried precursor gel with steam, optionally followed by caustic washing, without the formation of crystalline phases other than type Y zeolite being observed. Advantageously, the pre-shaped bodies prepared with the precursor gel of Y zeolite, when subjected to the process of the invention, will have their outer surface covered by type Y zeolite crystals. The molecular sieves so obtained may be employed as catalysts or adsorbents in various processes of the chemical or oil industry.
