The hierarchically mesoporous Hβ zeolite was synthesized by alkali treatment to commercial Hβ zeolite in NaOH solution. The composite carrier was prepared by mixing the hierarchical Hβ zeolite and Al2O3.The hierarchical NiWP/HβAl2O3 catalysts were prepared by incipient wetness impregnation method, and characterized by means of XRD, BET and TEM. The hydrodearomatization of the prepared NiWP/HβAl2O3 catalyst was evaluated in a miniature fixed bed reactor with fluid catalytic cracking diesel as raw material. The results suggested that the prepared NiWP/HβAl2O3 catalyst has an excellent hydrodearomatization activity, and under the condition of the reaction temperature 360 ℃, reaction pressure 8.0 MPa, hydrogen to oil volumetric ratio 800 and liquid hourly space velocity 1.0 h-1, the cetane number was increased from 7.21 of feed to 46.96 of product.
