摘要：

Novel hierachically porous material Beta-MCM-48 was successfully synthesized from Beta zeolite seeds by two-step hydrothermal crystallization method using Cetyltrimethylammonium Bromide as the mesostructure directing agent. Beta-MCM-48 composite synthesized at the optimization conditions possessed Beta microporous structure and cubic Iad mesoporous structure simultaneously. Meanwhile, the acidity of Beta-MCM-48 was similar to Beta zeolite and higher than MCM-48 mesoporous material. A series of Al2O3-Beta-MCM-48 supported NiMo catalysts with different Beta-MCM-48 contents were prepared by the incipient-wetness impregnation method. The catalytic performances were evaluated using DaQing Fluid Catalytic Cracking diesel as feedstock in a high pressure microreactor. Hydrodesulfurization results indicated that NiMo/Al2O3-Beta-MCM-48 catalyst exhibited better activities than that of NiMo/Al2O3 traditional catalyst. NiMo/Al2O3-Beta-MCM-48 catalyst obtained the highest activity as the Beta-MCM-48 content in the support was 20 wt %, and the corresponding sulfur content of the hydrotreated product reached to 23.02 mu g g(-1).
