    摘要: This patent describes economical and environment-friendly processes for the synthesis of anionic clays. It involves reacting a slurry comprising boehmite, which has been peptized with acid with a divalent metal source followed by addition of source of base. The slurry is then hydrothermally aged. There is no necessity to wash or filter the product and 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, polymeric nanocomposites and other commodity products that contain anionic clays.

    摘要: This invention relates to a process for the preparation of anionic clay and boehmite-containing compositions. These compositions may also contain unreacted trivalent metal source and/or divalent metal source. The process involves subjecting a precursor mixture comprising a divalent metal source and a trivalent metal source to at least two aging steps, wherein at least once between two aging steps an aluminum source is added. An advantage of the invention is that the crystallinity of the boehmite in the composition can be tuned.

    摘要: Anionic clay compounds such as hydrotalcite-like compounds can be made by a process wherein a non-hydrotalcite-like compound (or a hydrotalcite-like compound) are heat treated and then hydrated to form hydrotalcite-like compounds having properties (e.g.., increased hardness and/or density) that differ from those of hydrotalcite-like compounds made by prior art methods wherein non-hydrotalcite-like compounds (or hydrotalcite-like compounds) are not similarly heat treated and hydrated to form such hydrotalcite-like compounds.

    摘要: A catalyst for effectively removing NOx by using NH3 as a reducing agent is disclosed. Particularly, a vanadia impregnated onto Ti-PILC (titania-pillared interlayer clay) is disclosed, which is prepared by the generally known technology. More specifically, a V2O5/Ti-PILC catalyst is disclosed, in which NOx contained in the flue gas from an electric power plant and the like (an excessive amount of SO2 being present in the flue gas stream) is reacted with NH3 (which is injected as a reducing agent) over a vanadia impregnated onto a Ti-PILC, so that they can be converted into harmless nitrogen and water. The V2O5/Ti-PILC catalyst is employed for reducing NOx contained in the exhaust gas stream as well as the large amounts of SO2 into nitrogen and water. The catalyst is prepared by pillaring a titania to a clay by a pillaring method. The V2O5/Ti-PILC catalyst prepared in the present invention reveals a superior NO removal activity under dry and wet conditions compared with the commercial V2O5—WO3/TiO2 catalyst.

    摘要: A process for the production of a bleaching clay product which includes the steps of selecting a naturally occurring hormite clay product, cleaning and crushing the clay product to form clay clumps less than 2 in. in diameter, aging the crushed hormite clay and activating the clay with extremely small amounts of acid, in the range of less than 1 percent, by weight. The process may also be conducted without an aging step. Also, an acceptable bleaching clay product can be produced without the addition of any acid to the aged hormite clay.
