摘要:
利用快速凝固技术制备了Ni23 3Zr6 7Al64Cu2 3Ce3.7(原子数分数)非晶态催化合金,用碱洗抽Al的方法加以活化,制成大比表面积Ni基非晶合金催化剂,然后在苯加氢反应上测试了其催化性能.结果发现,这种新型催化材料的比活性高出常规Raney Ni催化剂37.5%;反应动力学分析表明,其反应级数对氢基本上表现为一级,反应活化能约为31.2 kJ/mol,低于常规Raney Ni催化剂.最后推导出其在苯加氢反应上的动力学方程.
Abstract:
Ni23 3Zr6 7Al64Cu2 3Ce3.7 (atomic fraction) amorphous catalytic alloy was prepared by rapid solidification technology, activated by alkali washing and pumping Al, and a large specific surface area Ni-based amorphous alloy catalyst was prepared, and then its catalytic performance was tested on benzene hydrogenation. The results showed that the specific activity of this new catalytic material was 37.5% higher than that of conventional Raney Ni catalyst. The reaction kinetic analysis showed that the reaction sequence was basically one stage for hydrogen, and the reaction activation energy was about 31.2 kJ/mol, which was lower than that of conventional Raney Ni catalyst. Finally, the kinetic equation for benzene hydrogenation reaction is derived.
