采用化学还原法制备了非晶态Ni-B超细粒子催化剂,所含两种粒子的粒径分别为5～20nm和150nm左右.对环戊二烯常压液相加氢反应的活性测试结果表明,该催化剂具有很高的活性和选择性,并且在加氢反应中具有替代Raney Ni和Pd/C 催化剂的工业应用潜力.动力学测量表明,在该催化剂上,环戊二烯选择加氢生成环戊烯的反应为零级,环戊烯生成环戊烷的反应为近似一级. Amorphous Ni-B ultrafine particle catalyst was prepared by chemical reduction method, and the particle size of the two particles was about 5 ~ 20nm and about 150nm, respectively. The results of the activity test of hydrogenation of cyclopentadiene at atmospheric pressure Indicating that the catalyst has high activity and selectivity, and has potential for industrial application in the hydrogenation reaction instead of Raney Ni and Pd / C catalysts.Kinetic measurements show that on this catalyst, cyclopentadiene is selectively hydrogenated The reaction to produce cyclopentene is zero order and the reaction of cyclopentene to cyclopentane is approximately one order.
