Abstract

Abstract: A support(denoted AM) was prepared using pseudo-boehmite and mordenite.Ni-B and NiPtB amorphous catalysts were prepared on the support by the impregnation method followed by chemical reduction with a KBH4 solution.And the catalysts were characterized by X-ray diffraction(XRD), environment scanning electron microscope(ESEM), inductively coupled plasma(ICP), H₂-temperature programmed reduction(H₂-TPR), differential thermal analysis(DTA), and BET.Benzene hydrogenation was used as a probe reaction to evaluate the effect of addition of small quantities of Pt on the NiB/AM catalyst.The results show that Pt can promote the reduction of NiO and the formation of active sites, leading to smaller catalyst particles and better dispersion of active metal particles on the support.The catalytic activity, sulfur resistance and thermal stability were remarkably improved by Pt doping of the NiB/AM catalyst.

Key words: NiB amorphous alloy, benzene hydrogenation, Pt doping, sulfur resistance
