    • 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.
    • 适用于含有5至75重量%镍的脂肪或油的氢化的颗粒催化剂可以通过将表面加权平均直径D [3,2]的过渡氧化铝粉末在1μm至20μm范围内 与镍氨络合物的水溶液,然后加热沉积不溶性镍化合物,然后还原后者。 含有高达约55重量%的镍的催化剂的镍表面积高于130m 2 / g的镍。 具有使用平均孔径高于12μm的氧化铝制成的具有更大镍含量的催化剂可具有较低的镍表面积,但令人惊奇的是活性和选择性。
