Abstract: Meso-microporous composite materials of larger mesoporous aperture possess open pores of mesoporous materials and appropriate acidity, so it is helpful to the diffusion and removal of macromolecular sulfide, which could led to the result of deep desurfurization. Beta-MCFs (TMB/P123=0.4, 0.5, 1.0, 2.0 or 3.0) meso-microporous composite materials were synthesized from zeolite Beta nanoclusters by self-assembly method using P123 as the mesostructure directing agent under the basic condition in this thesis. The corresponding composite supports were produced by mechanical mix with Al2O3 (1:4), then the supported Ni(3.5wt%)Mo(15wt%) catalysts were prepared by two-step incipient-wetness impregnation of ammonium heptamolybdate and nickel nitrate. The typical physical-chemical properties of the supports and the catalysts were characterized by XRD, IR, NH3-TPD, SEM, TEM and Nitrogen adsorption–desorption analysis, etc. The hydro desulfurization evaluation results of FCC diesel with the sulfur content of 1013.8 µg•ml-1 showed that in the appropriate proportion of TMB/P123 range, the greater the ratio, the better desulfurization efficiency we received, on the TMB/P123 = 0.5, the corresponding catalyst exhibited the highest HDS activity, as high as 98.1%, and the product with the sulfur content of 19.8 µg•ml-1 was achieved.
