A series MoO₃/Al-SBA-15 catalysts modified by HCl were prepared by evaporation induction method. The catalysts were characterized by XRD, BET, TEM and NH₃-TPD. The results showed that the modification of the catalyst retained the hexagonal structure of SBA-15 with ordered pore structure. The pore size of the modified samples was about 8 nm with wall thickness of about 4 nm. The catalysts were typical mesoporous molecular sieves over which the active components were well distributed. The Al-SBA-15 loaded with MoO₃ had good hydrocracking activity after prevulcanization. Under the condition of 14.9% MoO₃ loading, the total yield of naphtha and aviation kerosene fraction was 79.21%. The naphtha had the highest aromatic potential of 72.4, which was an excellent feedstock for reforming to produce aromatics. The high BMCI value of the cracked tail oil was not suitable for ethylene production by cracking.
