摘要：
The nano NiCe/Al2O3 catalyst was prepared with nano NiCe particles with hydrogen storage property prepared by H2 arc plasma method and characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM). The results showed that nano NiCe particles were sphericity polyhedron and Ce was in superficial layer. The structure of NiCe/Al2O3 catalyst was shell model alveolate and the stength of NiCe adherering to the surface of Al2O3 was weak. In the pyrolysis gasoline first stage hydrogenation, the activity and selectivity of NiCe/Al2O3 catalyst were high.
