| 摘 要： | 以介孔分子筛SBA-15为载体，担载Co—Mo双金属活性组分制备了深度加氢脱硫催化剂。通过XRD和BET表征表明，负载金属后SBA-15分子筛仍然保持二维晶相结构，表面积略有下降。以直馏柴油为原料，在固定床反应器上评价了催化剂的脱硫反应活性的结果表明，SBA-15介孔分子筛Co—Mo的负载量为W（CoO）=5％，w（MoO3）=25％；脱硫适宜的反应条件为：反应温度360℃，压力4．0MPa，氢油体积比400．0，空速2．0h^-1。在此条件下，柴油硫含量可由1350μg／g降至39μg／g。

| Abstract: | High performance diesel hydrodesulfurization (HDS) catalysts were prepared by depositing Co-Mo sulfides on mesoporous SBA-15 molecular sieves.The prepared catalysts were characterized by XRD and BET.The prepared catalysts preserved well-ordered 2D hexagonal structure of SBA-15,the surface area decreased slightly.On fixed bed reactor,the HDS activity of prepared catalysts were evaluated with a straight-run diesel fraction as the feed.Results showed that the maximum HDS activity was observed at Co-Mo(5%,25%),... |
