| Abstract: | A series of the hydrocracking catalysts with constant WO3 loading and different NiO contents were prepared by impregnation method and characterized by XPS and TEM. The results indicated that the introduction of Ni was beneficial to sulfidity enhancement of W phase, and WS2 slab length increased and layer numbers of WS2 slabs first increased and then decreased with the increase of NiO contents. The hydrocracking activity of these catalysts were investigated using dodecane as the model compound in a microreactor. It results showed that variation trend of the catalyst activity was similar to that of layer numbers of WS2 slabs and the hydrocracking catalyst with 6% NiO （ mass fraction） exhibited the optimal activity and had the most layer number of WS2 slabs. |
