Using Al2O3, HNO3 and other components as binder component, Ni as active component, ZnO as sulfur storage material, the adsorptive desulfurization catalyst was prepared by equal volume impregnation method. The effects of the Al/Si mass ratio, kneading time of the supporter, adding quality percentage of nitric acid and binder component on catalyst’s desulfurization performance and mechanical strength were investigated. The results showed that the catalyst’s desulfurization performancewas improved when the adding quality of nitric acid, pseudo boehmite and kieselguhr was increased. The desulfurization performance was increased and then decreased with increasing of Al/Si mass ratio, increased and then kept stable with increasing of kneading time. The catalyst’s mechanical strength was improved when the Al/Si mass ratio increased, the adding quantity of nitric acid decreased, pseudo boehmite and kieselguhr increased and the kneading time increased.
