  • Patent number: 8992768
    Abstract: A highly active nickel carrier catalyst based on aluminium oxide has a nickel content of approximately 20 to 70 wt.-% (as Ni) and optionally comprises a bonding agent and optionally a promoter, selected from the compounds of Mg, Ti, Pb, Pt, Ba, Ca and/or Cu, wherein the size of the Ni crystallites in the reduced state is in the range of approximately 3.5 to 4.5 nm and the distortion factor of the Ni crystallites is approximately 2 to 5%. In a method for the reduction of the content of sulphur compounds in hydrocarbon-based fuels by selective adsorption of the sulphur compounds on a nickel catalyst, a nickel catalyst based on aluminium oxide is used, particularly the nickel catalyst described above. A nickel catalyst based on aluminium oxide may be used for reducing the sulphur compound content in hydrocarbon-based fuels by selective adsorption of the sulphur compounds on said catalyst and/or for the hydrogenation of aromatic compounds.

  • Publication number: 20130266507
    Abstract: The subject of the invention is a method for the synthesis of zeolites, comprising the following steps: a) providing a silicon source; b) providing an aluminium source; c) optionally providing at least one template; d) mixing the silicon source, aluminium source and optional template in order to produce a synthesis gel; e) grinding the synthesis gel; f) treating the ground synthesis gel under hydrothermal conditions in order to produce crystalline zeolite, as well as zeolites that can be obtained according to this method. The products obtained according to the method can be used as catalysts or catalyst supports.

  • Patent number: 7897136
    Abstract: A method is described for the manufacture of hydrotalcites by using at least one compound of a bivalent metal (Component A) and at least one compound of a trivalent metal (Component B), wherein at least one of these components is not used in the form of a solution, characterized in that a) at least one of the Components A and/or B which is not used in the form of a solution, shortly before or during mixing of the components, and/or b) the mixture containing the Components A and B is subjected to intensive grinding until an average particle size (D50) in the range of approx. 0.1 to 5 ?m is obtained, and optionally, after aging treatment or hydrothermal treatment, the resulting hydrotalcite product is separated, dried, and optionally calcinated.

  • Patent number: 6428929
    Abstract: The invention relates to negative electrodes for high-energy lithium-ion batteries, which contain Li—Me oxide with Me═Mn, Cr, Ni or Co as active cathode material, and to their production. The electrode composition contains a latex additive based on an acrylic acid derivative copolymer and a polymer binder containing butadiene units. The electrodes are produced by dispersing the carbon black, homogenized with the latex additive, in a solvent and mixing it with the graphite, and by stirring it to form a homogeneous composition, and not incorporating the polymer binder and applying the electrode composition thus obtained to the support substrate until the final stage.
