Abstract

Abstract

Micro-mesoporous Hβ/Al-SBA-15 composite molecular sieves was prepared by post-synthesis method and characterized by XRD, N₂ sorption, Py-FTIR, NH₃-TPD, SEM and TEM. With the Hβ/Al-SBA-15 composite as support, Ni-W/Hβ/Al-SBA-15 catalyst was prepared through impregnation and its catalytic performance in the hydrocracking of naphthalene to BTX was investigated. The results verified that the Hβ/Al-SBA-15 composite are provided with both micropores and mesopores. Both Bronsted acid and Lewis acid sites are present on the surface of Hβ/Al-SBA-15 and its acidity is stronger than that of SBA-15. After loading Ni and W, the Ni-W/Hβ/Al-SBA-15 catalyst with moderate acidity and micro-mesoporous structure exhibits high activity in the hydrocracking of naphthalene to BTX; the conversion of naphthalene reaches 96%, with the selectivity of 61.1% to BTX.
