A catalyst intermediate is also described which comprises a cobalt compound, comprising a Co(II)/Co(III) hydrotalcite phase and a CO3O4 cobalt spine) phase, wherein the ratio of cobalt hydrotalcite phase: cobalt spine) phase is less than 0.6:1, said cobalt hydrotalcite phase and said cobalt spine) phase being measured by X-ray diffractometry.

    摘要： Copper/alumina compositions for use as, e.g., catalysts are made by impregnating a porous transition alumina support with an aqueous solution of a copper ammine carbonate complex, draining off any excess of the impregnating solution, and then heating the impregnated support to a temperature above 80° C. to decompose the complex, thereby depositing a basic copper carbonate compound on the surfaces of the pores of the transition alumina support. After reduction, the composition has a high copper surface area, expressed per unit weight of copper in the composition.

    摘要： A particulate catalyst suitable for the hydrogenation of fats or oils containing 5 to 75% by weight of nickel may be made by slurrying a transition alumina powder having a surface-weighted mean diameter D[3,2] in the range 1 &mgr;m to 20 &mgr;m with an aqueous solution of a nickel ammine complex, followed by heating to deposit an insoluble nickel compound and then reducing the latter. Catalysts containing up to about 55% by weight of nickel have a nickel surface area above 130 m2/g of nickel. Catalysts having greater nickel contents made using alumina having an average pore diameter above 12 &mgr;m may have a lower nickel surface area but are surprisingly active and selective.

    摘要： A method for the preparation of an eggshell catalyst is described comprising the steps of i) immersing shaped units of an oxidic support having a smallest unit dimension ≧0.5 mm in a solution of cobalt ammine carbonate, ii) heating the solution to a temperature between 60 and 120° C. to precipitate cobalt compounds onto the surface of the shaped units, iii) separating the resulting supported cobalt compounds from the remaining solution, and iv) drying the supported cobalt compounds. The cobalt compounds may be reduced to provide catalysts suitable for the hydrogenation of unsaturated compounds or the Fischer-Tropsch synthesis of hydrocarbons.
