Abstract: The MoP/A l₂O₃ catalyst precursor was prepared with impregnation method and a series of A l₂O₃supported molybdenum phosphide catalysts were prepared by convention reductionpassivationreduction method using the precursor. The catalytic activity of MoP/A l₂O₃ was investigated on different conditions in solvent oil C6, C7 as model compounds. The results showed that the application conditions of MoP/A l₂O₃ catalyst with 22% and 14% molybdenum trioxide content were reaction temperature 210 ℃, space velocity 1.5 h^-1 and reaction temperature 230 ℃ and space velocity 1.5 h^-1 respectively.

摘要： 用浸渍法制备了 Mo P / A l₂O₃ 催化剂前体, 通过该前体采用体外还原 - 钝化 - 还原的方法制备了 Mo P /  A l₂O₃。选用C ₆、 C ₇ 溶剂油作为模型化合物, 以  A l₂O₃ 为载体, 考察不同实验条件下磷化钼催化剂的活性。结果表明, Mo O₃ 质量分数为2 2%的磷化钼催化剂的使用条件为反应温度2 1 0℃、 空速1. 5h^-1; 当 Mo O₃ 质量分数为1 4% 时, 其反应条件为反应温度2 3 0℃、 空速1. 5h^-1。
