The phosphotungstic acid(HPW)/nano-ZSM-5 catalyst was prepared by the impregnation method. When the nano-ZSM-5 is supported by HPW alone, the Keggin structure HPW changes to a Dawson structure heteropoly compounds, and the Keggin structure remains unchanged after binding with nickel salt. With oxidative desulfurization of organic sulfides as a probe, the oil desulfurization rate in simulation oils with dibenzothiophene components of n-octane reaches 94.5% at 40℃.
