The present invention relates to a catalyst for synthesizing ethylene amine and a method for preparing ethylene amine. The catalyst is formed of a main active component, an auxiliary agent, and a carrier processed by ammonification. The main active component is Ni or Co, the auxiliary agent comprises one or more of Fe, Cu, Ru, Re, K, Zn, B and other metal or oxides thereof, and the ammonified carrier is ammonified SiO 2 or Al 2 O 3 . In the total weight of the catalyst, the main active component accounts for 1~40%, and the auxiliary agent accounts for 0.1~20%. The catalyst of the present invention is characterized in that the used carrier needs to be ammonified specially. The ethylene amine product synthesized in a hydrogen condition by using the catalyst of the present invention to carry out an ethanolamine ammonification reaction presents high activity, high selectivity and stability. |
