Patent number: 8992768Abstract: 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.Type: GrantFiled: March 13, 2008Date of Patent: March 31, 2015Assignee: Süd-Chemie IP GmbH & Co.

Patent number: 6428929Abstract: 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.Type: GrantFiled: May 19, 2000Date of Patent: August 6, 2002Assignee: NBT GmbHInventors: Jürgen Koy, Bernhard Metz, Roland Wagner, Dieter Bechtold
