英文摘要 | Four hydrocracking catalysts supported on different kinds of modified Y zeolites were studied by utilizing EXAFS (Extend X-ray Absorption Fine Structure). The results show that the Ni and W in the catalysts have not been thoroughly sulfided. Apart from the sulfided state, the tungsten in the sulfided catalysts exists in a state of oxosulfided tungsten while some nickels exist in their oxide state. In addition, it also shows that there are NiWS species in the sulfided catalysts and the amount of which shows a good correlation with the Bronsted acid sites of the mixture supports of zeolites and gamma-Al2O3. It means that the NiWS species maybe exist mainly in the cavities of the zeolites and the tungsten in micropore zeolites is more difficult to be sulfided than that on the surface of amorphous Al2O3. |
