The composite nickel phosphotungstate(NiPW)-HZSM-5 catalyst was prepared by the impregnating technique on nanocrystalline HZSM-5 zeolite. The catalysts were characterized by in-situ electron paramagnetic resonance and in-situ pyridine adsorption Fourier-transform infrared. The results show that the deep hydrodesulfurization of fluid catalytic cracking(FCC) gasoline are enhanced over the NiPW-HZSM-5 catalyst. Heteropoly acid(HPW(Ⅲ))-Ni(Ⅱ) on the nanocrystalline HZSM-5 zeolite is the active center of deep hydrodesulfurization of FCC gasoline. The effect of the acidity on the activity over different catalysts in deep hydrodesulfurization of FCC gasoline was investigated.
