3种镍基催化剂对苯乙酮的催化加氢对比研究
Comparative study on the hydrogenation of acetophenone catalyzed by three kinds of Ni-based catalyst
【摘要】 制备了Ni- B/SiO2 非晶态催化剂、RaneyNi催化剂和漆原镍催化剂 ,采用XRD、SEM等对非晶态特征进行表征。分别用这 3种镍基催化剂对苯乙酮进行催化加氢实验 ,实验表明 ,Ni- B/SiO2 非晶态催化剂的催化活性和稳定性明显优于其他两种镍基催化剂。
【Abstract】 The supported Ni-B/SiO 2 amorphous catalyst prepare d by chemical reduction exhibited the highest catalytic activity and stability in the hydrogenation of acetophenone in comparison with Raney Ni and U-Ni-A cata lysts.The structure of catalyst was characterized by XRD and SEM.
