提出通过硅改性来增加催化剂活性金属负载量的一种方法，采用压汞法和 N2吸附法对硅改性后的三次纳米自组装 Mo-Ni/γ-Al2O3催化材料的孔性质进行表征。压汞法数据表明，催化材料的孔容为0.66~0.90 cm3?g-1，比表面积为122~175 m2?g-1，30~100 nm 的孔径分布高达69.08%。结果表明，加硅后催化剂金属上量增加，单位体积活性金属量降低以及堆积密度降低，而且其催化效果在200 h 后趋于稳定，具有脱硫、加氢脱残碳效果好等优点。

A new method was put forward to increase the amount of loading active metal by the silicon modification. The pore properties of silicon modified third nano self-assembly macroporous Mo-Ni/γ-Al2O3 catalytic materials were characterized by mercury porosimetry and N2 adsorption method. It is shown that the catalytic materials have pore volume of 0.66~0.90 cm3?g-1, specific surface area of 122~175 m2?g-1, and the pore size distribution reaches up to 69.08% at the range of 30~100 nm by the mercury porosimetry. The results show that the amount of loading active metal are increased, the amount of unit volume active metal and the bulk density are decreased by the silicon modification;The catalytic performance of hydrodesulfurization and hydrodecarbonresidue is better when the hydrogenation reaction tends to stable after 200 h.
