摘要： 采用浸渍法合成了镍盐复合的磷钨酸(HPW)/纳米晶HZSM-5固体酸催化剂，其在催化裂化(FCC)汽油加氢改质反应中显示出了良好地深度加氢脱硫活性。 原位电子自旋共振和原位吡啶吸附红外光谱表征手段的研究结果表明，纳米晶HZSM-5沸石上Ni(Ⅱ)结合3电子还原态的HPW(Ⅲ)是FCC汽油深度加氢脱硫反应的活性中心。 探讨了多酸基催化剂在FCC汽油深度加氢脱硫反应中活性改善的原因。

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
