摘　　要：利用机械混合法合成了一系列HUSY-γ-Al2O3介孔-微孔复合分子筛,并以其为载体负载W-Ni活性组分,制备加氢精制催化剂,并对抚顺页岩油进行加氢精制研究。得出最佳制备条件为:焙烧温度为500℃,HUSY分子筛的最佳质量分数为15%。通过IR、N2吸附-脱附、吡啶红外吸附等表征手段对所合成的HUSY-γ-Al2O3复合分子筛进行表征,结果表明,γ-Al2O3与HUSY相互影响,产生协同作用;合成的HUSY-γ-Al2O3复合分子筛的比表面积介于HUSY和γ-Al2O3之间;复合分子筛具有较高的酸性,有利于C—S与C—N键的断裂。Based on the advantages of the two materials （ γ-Al2O3 and ttUSY）, a series of meso-microporous composite molecular sieves are synthesized by mechanical mixing method. The hydrofining catalyst is prepared by loading W-Ni active component and applied to the hydrofining of Fu Shun shale oil. The optimal conditions are shown as follows ： 500℃ of calcination temperature and 15% of HUSY on HUSY-γ-Al2O3 composite catalyst （mass ratio）. Infrared, N2 adsorption-desorption isotherms and pyridine Fourier transform-infrared（Py-FT-IR） are used to characterize the HUSY- γ-Al2O3 composite molecular sieve. The resuks show that the γ-Al2O3 and HUSY influence each other and interact synergistically. The surface area of the composite molecular is ranged between HUSY and γ-Al2O3. The high acidity of HUSY-γ-Al2O3 composite molecular sieve is beneficial to the rupture of C--S and C--N bonds.
