摘要：
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 γ-Al2O3-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/γ-Al2O3. 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 0.5 has the best catalytic properties, whereas for Co-Mo/γ-Al2O3 catalyst the best Co/Mo atomic ratio is 0.35. © 2007 Institute of Coal Chemistry, Chinese Academy of Sciences.
