YAN Yuling, SONG Jinyu, WANG Dingcong
Bulk NiAl2O3 catalysts was synthesized in the way of supersolubilization nanometer selfassembly. The bulk NiAl2O3 catalyst was characterized by Xray 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 NiAl2O3 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 NiAl2O3 catalyst is between 186 m2/g to 324 m2/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.
