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.

Abstract: The invention relates to a process for preparing a catalyst for the desulfurization of hydrocarbon streams, which comprises the steps: (a) preparation of an aqueous suspension comprising: a thermally decomposable copper source, a thermally decomposable molybdenum source, and a solid zinc source; (b) heating of the suspension to a temperature at which the thermally decomposable copper source and the thermally decomposable molybdenum source decompose so that a suspension of a precipitate comprising zinc compounds, copper compounds and molybdenum compounds is obtained; (c) cooling of the suspension obtained in step (b); (d) separation of the precipitate from the suspension; (e) drying of the precipitate. The invention further relates to a catalyst which can be obtained by the process of the invention and also to its use for the desulfurization of hydrocarbon streams.
