摘　　要：采用浸渍法制备了纳米晶ZSM-5负载的磷钨酸复合固体催化剂,纳米晶ZSM-5上单独负载磷钨酸时,Keggin结构磷钨酸转变为Dawson结构多酸化合物,结合镍盐后Keggin结构保持不变。以有机硫化物氧化脱硫为探针反应的研究结果表明,在低温(40℃)反应条件下,含二苯并噻吩有机硫组分的正辛烷模拟油品的脱硫率高达94.5%。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, dibenzothiophene components of n-octane reaches 94. 5 % the oil desulfurization rate in simulation oils with at 40 ℃.
