Abstract：Inorder to improve theactivityandstabilityof Ni-basedcatalysts in thereductiveaminationoffurfural， NiPd/ SiO2 bimetallic catalysts were prepared by the co-impregnation method and used for the reductive amination of furfural to furfurylamine using an aqueous ammonia solution and molecular hydrogen asan amine source andareducing agent，respectively.The efects of Ni/Pd molar ratio，reaction temperature，hydrogen pressure and catalyst dosage on furfural conversion and furfurylamine selectivity were investigated.Meanwhile，thereusability and the universality ofthecatalyst were studied.Theresults show thatacompleteconversion of furfuraland91.6%furfurylamineyield wereachievedover the optimalNiPd（1：4）/SiO catalyst under the reaction conditions of 130‰ and2 2 MPa H2 for 3h .Furthermore，the catalyst still shows good activity after four recycle times.Additionally，the catalyst exhibits high performance in the reductive amination of various aldehydes to the corresponding primary amines.
