Abstract

Abstract: 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.

Key words: heteropoly acid, electron paramagnetic resonance, hydrodesulfurization, fluid catalytic cracking gasoline, nickel
