摘要： This patent describes an economical and environment-friendly continuous process for the synthesis of anionic clays with carbonate and/or hydroxide anions as the charge-balancing interlayer species. It involves reacting a slurry comprising aluminium trihydrate and/or its calcined form, with a magnesium source. There is no necessity to wash or filter the product. It can be spray dried directly to form microspheres or can be extruded to form shaped bodies. The product can be combined with other ingredients in the manufacture of catalysts, absorbents, pharmaceuticals, cosmetics, detergents, and other commodity products.

摘要： The present invention relates to a process for the preparation of doped pentasiltype zeolite, which process comprises the steps of: a) preparing an aqueous precursor mixture from a silicon source, an aluminium source, and doped non-zeolitic seeds, and b) thermally treating the precursor mixture to form a doped pentasil-type zeolite. The term "non-zeolitic seeds" includes seeds made from materials selected from the group consisting of (i) X-ray amorphous materials, (ii) milled crystalline materials, such as milled zeolites, that have a relative crystallinity of not more than 75%, and (iii) crystalline materials other than zeolites, such as clays (e,g, bentonite and kaolin) and (low) crystalline aluminas.

摘要： A process for the preparation of a metal-doped pentasil-type zeolite comprising 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 IIb of the Periodic System, and b) thermally treating the precursor mixture to form a metal-doped pentasil-type zeolite. With this process, metal-doped pentasil-type zeolites can be prepared while the risk of precipitation of the dopant as a separate phase is minimised.

摘要： This patent describes economical and environment-friendly processes for the synthesis of anionic clays and anionic clay-like materials with acetate anions as the charge-balancing interlayer species. It involves combining a slurry of a gibbsite or its thermally treated form with a slurry or solution of a magnesium source and magnesium acetate. The product is not washed, needs no filtration and exists in a close to neutral pH condition. It can be spray dried directly to form microspheres or can be extruded to form shaped bodies. Because of the absence of foreign salts the product can be combined with other ingredients in the manufacture of catalysts, absorbents, pharmaceuticals, cosmetics, detergents, and other commodity products that contain anionic clays.

摘要： 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.
