摘要： 制备了多级孔TiO2⁃Al2O3载体和Ni2P/TiO2⁃Al2O3催化剂，将该催化剂与负载Ni2P/介孔Al2O3和Ni2P/γ⁃Al2O3进行了催化性能对比。分别用正交设计法和单因素考察法,对反应温度、氢油体积比、质量空速和反应压力等工艺条件对反应结果的影响进行了考察，并得出了优化后的工艺条件。结果表明，Ni2P/TiO2⁃Al2O3较Ni2P/γ⁃Al2O3和Ni2P/介孔Al2O3的催化活性和选择性都高；以多级孔Ni2P/TiO2⁃Al2O3为催化剂时，萘的转化率和十氢萘选择性受反应压力和温度影响较大，受氢油体积比和空速的影响较小。多级孔Ni2P/TiO2⁃Al2O3催化剂在加氢脱萘反应中的最佳反应条件为：反应温度300 ℃，反应压力4 MPa，氢油体积比500，质量空速1 h⁃1，此时萘的转化率和十氢萘选择Ni2P/TiO2⁃Al2O3性分别为99.2%和72.0%。

Abstract: The carrier of hierarchical porous TiO2⁃Al2O3 and the catalyst Ni2P/TiO2⁃Al2O3 were prepared. The catalytic performance of the Ni2P/TiO2⁃Al2O3 was compared with the Ni2P loaded on the mesoporous Al2O3  and γ⁃Al2O3. The influence of the technological conditions, including reaction temperature, hydrogen oil ratio, mass space velocity and reaction pressure, were investigated by Orthogonal test and single factor exploration, respectively. The optimized technological conditions were obtained. The results showed that the hydrogenation catalyst Ni2P/TiO2⁃Al2O3 possessed more excellent de⁃aromatic rate and the selectivity of decahydronaphthalene compared with the ordinary catalyst of Ni2P/γ⁃Al2O3 and Ni2P/Al2O3. For the de⁃aromatic rate and the selectivity of decahydronaphthalene, the reaction pressure and temperature had more significantly affection to the hydrogen / oil ratio and the mass space velocity. According to the results of orthogonal test, the optimum reaction conditions of the hierarchical porous Ni2P/TiO2⁃Al2O3 catalyst in the hydrodeaphthalene reaction were investigated. The reaction temperature was 300 ℃, the reaction pressure was 4 MPa, the hydrogen / oil ratio was 500, and the mass space velocity was 1 h-1. The removal rate of naphthalene and the selectivity of decahydronaphthalene reached the highest, which were 99.2% and 72.0%, respectively.
