    • An amorphous alloy catalyst for hydrogenation and its preparation method are disclosed herein. The catalyst essentially consists of nickel ranging between 60 and 98 wt %, iron ranging between 0 and 20 wt %, one doping metal element selected from the group consisting of chromium, cobalt, molybdenum, manganese and tungsten ranging between 0 and 20 wt %, and aluminum ranging between 0.5 and 30 wt % based on the weight of said catalyst, wherein the weight percentages of iron and the doping metal element component may not be zero at the same time; and just one broad diffusion peak appears at about 2 &thgr;=45±1° on the XRD patterns of the catalyst within 2 &thgr; range from 20 to 80°. The catalyst herein can be used in processes for hydrogenation of unsaturated compounds such as olefin, alkyne, aromatics, nitro, carbonyl groups, nitrile and soon, and for hydrorefining of caprolactam in particular.
    • 本文公开了一种用于氢化的无定形合金催化剂及其制备方法。 该催化剂基本上由在60至98重量%之间的镍范围内,铁范围在0至20重量%之间,1种掺杂金属元素选自铬,钴,钼,锰和钨,其范围为0至20重量% 和铝的范围在0.5至30重量%之间,基于所述催化剂的重量,其中铁和掺杂金属元素组分的重量百分比可以不同时为零; 并且在20至80°的2θ范围内,在催化剂的XRD图上,在约2θ= 45±1°处仅出现一个宽的扩散峰。 本文的催化剂可用于不饱和化合物如烯烃,炔烃,芳族化合物,硝基,羰基,腈和不久的氢化方法,特别是加氢精制己内酰胺。
