Abstract: Bulk NiAl2O3 catalysts was synthesized in the way of supersolubilization nanometer selfassembly. The bulk NiAl2O3 catalyst was characterized by Xray diffraction (XRD) and the mercury porosimeter. The influence of affecting factors on physical properties of catalysts was investigated, such as the amount of urea and surfactant, and the amount of nikel oxide. The results show that bulk NiAl2O3 catalysts has a better bore structure, which is made from based amount plus 2 of surfactants, based amount plus 5 of urea and plus 3 of NiO. Specific area of the bulk NiAl2O3 catalyst is between 186 m2/g to 324 m2/g, bore diameter is 3~12 nm, and the diameter of bore is even and distribute concentration, witch is belong to medium and big bore scope, the bore permits is 0.45~0.89 mL/g. This bulk catalyst is a more ideal bulk catalyst which can satisfy the request of hydrogenation. This synthesize method has more merits,such as decreasing the dosage of surfactant and aqueous, operation craft simple, reaction can be controlled easily.Nanometer bulk catalyst has a good application value in industrialize production because of its better property than the residue oil hydrogenation catalyst.
