摘要:

采用共沉淀法制备了Ni/Al2O3加氢催化剂,在制备过程中引入交流电磁场对催化剂做强化制备,通过BET、SEM、XRD和TPR等方法对催化剂做表征,并将该催化剂应用于脂肪酸加氢反应中,考察了磁场强度对催化剂结构及加氢性能的影响。结果表明,制备过程中引入电磁场能够有效降低催化剂颗粒的团聚,增大催化剂的比表面积和平均孔径,提高催化剂的脂肪酸加氢活性。随着磁场强度的增强催化剂还原温度逐渐升高,结构稳定性增强,有效延长了催化剂的使用寿命。

关键词: Ni/Al2O3加氢催化剂, 磁场, 脂肪酸加氢

Abstract:

Ni/ Al2O3 hydrogenation catalyst was prepared by the co-precipitation method at different magnetic field intensity.The catalyst was applied to the hydrogenation of fatty acids and characterized by BET,SEM,XRD and TPR etc..The effects of magnetic field on catalyst structure and hydrogenation performance were investigated.The results showed that the magnetic field can effectively reduce the agglomeration between catalyst particles,increased the specific surface area and average pore size of the catalyst,and improved the activity of fatty acids hydrogenation.With the increase of the magnetic field intensity,the reduction temperature of the catalyst increased gradually,and the structural stability enhanced,which can effec-tively reduce the loss of the active component during the use and extend the service life of the catalyst.

Key words: Ni/Al2O3 hydrogenation catalysts, magnetic field, fatty acid hydrogenation
