摘要: 采用超增溶自组装法进行纳米Ni飊Al2O3 体相催化剂的制备。对所制备的Ni飊Al2O3 体相催化剂进行
了XRD和压汞法表征。通过实验考察了尿素质量分数、表面活性剂质量分数、NiO 质量分数等因素与Ni飊Al2O3 体
相催化剂物化特性之间的关系。结果表明,尿素质量分数为(基准+5)%,表面活性剂质量分数为(基准+2)%,NiO
质量分数为(基准+3)%时,Ni飊Al2O3 催化剂具有较好的孔结构。制备的体相催化剂的比表面积主要集中在186~
324m2/g;孔径在3~12nm,属于中、大孔范围,孔径大小均匀、分布集中;孔容较大,在0.45~0.89mL/g,能够满足
加氢催化剂的要求,是比较理想的纳米体相催化剂。该合成方法降低了表面活性剂和水的质量分数,操作工艺简
单,反应易于控制,制得的纳米粒子比现有的渣油加氢催化剂性能优良,具有工业化生产应用价值。

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.
