摘　　要：非晶态超微粒子镍合金催化剂的研究──Ⅱ．Ｎｉ－Ｂ催化剂对苯加氢反应动力学的研究李同信，张秀峰，李合秋（中国科学院大连化学物理研究所，大连１１６０２３）靳常德，蒋育林，崔建彤，王大庆（大连理工大学化工学院，大连１１６０１１）关键词非晶态超微粒子，镍基合...he catalytic behavior of ultra-fine amorphous Ni-B alloy catalysts for benzene hydrogenation was studied. Experimental results show that these catalysts have high activity, and with the increase of reaction pressure and the rise in reaction temperature the reaction rate is accelerated. The hydrogenation rate on Ni59.8B40.2 alloy is forty times as large as industrial catalyst Raney Ni under the same conditions. A study of the chemical kinetics shows that the benzene hydrogenation on the Ni59.8B40.2 catalyst is a first order reaction. Furthermore the activation energy of the reaction is calculated, which is 27. 0 kJ/mol. Therefore,this Ni-B alloy is a kind of high active catalyst for hydrogenation.
