Abstract
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 m /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.
