摘要：Y zeolite was modified with Zr by equal volume impregnation method. The effects of different amounts of Zr on the structure of modified Y zeolite, the physicochemical properties of the catalyst and the performance of hydrocracking reaction were investigated systematically. The modified Y zeolite and catalyst were characterized by X-ray diffraction (XRD), NH3 temperature programmed desorption (NH3-TPD), H2 temperature programmed reduction (H2-TPR) and transmission electron microscopy (TEM). The results show that Zr modification decreased the amount of acid sites of Y zeolite, and the trend became larger with an increase of Zr content. Moreover, Zr modification availably weakened the relation of metal species and support in the catalyst with Y zeolite, and improved the dispersion of W species on the catalyst surface. The hydrocracking reaction results suggested that VGO conversion over the catalyst with Y zeolite modified with Zr decreased compared with that with Y zeolite, and middle distillates increased about 20%(mass), as well as VGO conversion gradually decreased and the middle distillates slightly increased as the Zr content increased.
