The TiO ₂-SiO ₂-Al ₂O ₃ composite support was prepared by sol-gel method, and then the MoP/TiO ₂-SiO ₂-Al ₂O ₃ catalyst was prepared in the way of co-impregnation. XRD results show that the diffraction peaks of TiO ₂ crystalline phase is due to anatase and SiO ₂ is mostly amorphous dispersed in γ-Al ₂O ₃ cystal surface. After in-situ reduction, the hydrodearomatization (HDA) activity of the catalyst was investigated in the fixed bed reactor. The results suggest that the mole ratio of Ti, Si and Al have a great influence on the activity of composite support catalyst. HDA activity of the MoP/TiO ₂-SiO ₂-Al ₂O ₃ catalyst shows the highest activity (65.6%) when the ratio of n(Ti)∶n(Si)∶n(Al) was 1∶1∶4, the Mo loading amount is 20%. In addition, the results also show that the HDA rate of the catalyst with the composite TiO ₂-SiO ₂-Al ₂O ₃ support was 19.6% and 13.6% higher than the traditional cataslysts of γ-Al ₂O ₃ and SiO ₂-Al ₂O ₃, respectively.

        The SBS modified paving asphalt was developed from the Tahe crude oil containing more asphaltine .The problem about compatibility and storage stability between SBS polymer and the base asphalt were solved by adding compatilizer and stabilizer .This SBS modified paving asphalt which was up to JTG F40 -2004 technical specifications was evaluated by conventional test method and SHRP test method and compared with other SBS modified paving asphalt .The results show that the penetration index of SBS modified paving asphalt from the Tahe crude oil is more than 1 , the viscous -elastic range is 93.06 ℃, its equivalent softening point is 58 .08 ℃ and its equivalent break point is -34 .98 ℃ by conventional test method.So it has very small temperature sensitivity , wider viscous-elastic range and excellent high -low temperature performance .This kind o f SBS modified paving asphalt is applied in wider temperature range .I ts performance grade evaluated by SHRP test method reaches PG76 -34 .The performance grade of others compared SBS modified paving asphalt is PG70 -28.These results show SBS modified paving asphalt from the Tahe crude oil possesses excellent serviceability
