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.
