Abstract

Abstract

A series of HY-SBA-15(y) composite molecular sieves (y denotes the weight ratio of HY to SBA-15) were prepared by post-synthesis method and characterized by XRD, FT-IR, N₂ sorption, and NH₃-TPD. Ni-W/HY-SBA-15(0.10) catalyst was then prepared by impregnating HY-SBA-15(0.10) with Ni-W solution and used in hydrodearomatization of Maoming FCC diesel oil. The results indicated that HY-SBA-15 has both HY microporous and SBA-15 mesoporous structure and the microporous and mesoporous structures of HY-SBA-15 match remarkably well when the value of y is 0.10. Both Bronsted acid sites and Lewis acid sites are present on the surface of the composite molecular sieve HY-SBA-15(0.10) and its acidity is stronger than that of HY zeolite. When loading Ni and W on it, the Ni-W/HY-SBA-15(0.10) catalyst exhibits high activity in the hydrodearomatization and opening of aromatic rings.
