| 摘 要： | 采用等体积浸渍法制备了一系列不同Co/Mo原子比的碳纳米管（CNT）负载Co Mo催化剂。将该系列催化剂用于孤岛减压渣油加氢裂化反应，评价其催化效果，并在相同反应条件下与 γAl2O3负载Co-Mo催化剂的催化性能进行比较。结果表明，Co-Mo/CNT催化剂的催化效果略低于Co-Mo/γAl2O3催化剂。Co/Mo原子比对Co-Mo/CNT催化剂的催化效果有较大的影响。与相同载体的催化剂相比，当Co/Mo原子比为0.50时，Co-Mo/CNT催化剂具有最佳的催化效果，而Co-Mo/γAl2O3催化剂在Co/Mo原子比为0.35时具有最佳的催化效果。

| Abstract: | Carbon nanotube supported Co-Mo catalysts with different Co/Mo atomic ratio were prepared by pore volume impregnation. These catalysts were used in the hydro cracking reaction of Gudao vacuum residue, and the catalytic properties were compared with γAl2O3 supported Co-Mo catalysts under the same reaction conditions. It was found that the catalytic properties of Co-Mo/carbon nanotube (CNT) catalysts are inferior to Co-Mo/γAl2O3. However, the Co/Mo atomic ratio has great effect on the catalytic activity of Co-Mo/CNT; the Co-Mo/CNT catalyst with Co/Mo atomic ratio of 0.50 has the best catalytic properties, whereas for Co-Mo/γAl2O3 catalyst the best Co/Mo atomic ratio is 0.35. |
