Abstract

Abstract

Hβ zeolite was modified with different contents of F to prepare the Mo-Ni/F-Hβ catalysts. The Mo-Ni/F-Hβ catalysts were characterized by nitrogen physisorption, NH₃-TPD, XRD, Py-FTIR and SEM; the effect of modification to Hβ with F on the catalytic performance of Mo-Ni/F-Hβ in the sulfur transfer reactions such as etherification of mercaptan and alkylation of thiophene in FCC gasoline was then investigated. The results indicate that the Mo-Ni/F-Hβ catalyst prepared with 0.5% F-modified Hβ zeolite can promote the thioetherification and thiophene alkylation reactions and improve the selectivity of dienes hydrogenation. The introduction of F can enhance the medium strong acid content of Hβ zeolite, reduce the strong acid content, and increase the ratio of L/B acid sites, all these may contribute to improving the catalytic performance of Mo-Ni/F-Hβ in the sulfur transfer reactions of FCC gasoline.
