摘　　要：综述了己二腈催化加氢生产己二胺雷尼镍催化剂的制备方法,主要包括冶炼法、高能球磨法和激冷法制备铝镍合金。探讨了碱熔脱铝的活化条件,分析了活化后形成的催化剂微结构对其活性及选择性的影响,对比了与负载型非晶态合金催化剂制备方法的不同。Methods for preparation of Raney nickel catalysts for hydrogenation of adiponitrile to hexamethylendiamine were reviewed, including mainly preparation of Al-Ni alloys by smelting, high energy ball-milling and quenching. The condition for dealuminization with alkali fusion and the effects of micro- structure formed after activation on the activity and selectivity were investigated. Different methods for preparation of supported amorphous alloys catalysts were compared.
