摘要：

An evidence for the synergetic effect between the stacked bed of Mo/gamma-Al2O3 and Ni/gamma-Al2O3 in the hydrodenitrogenation (HDN) reaction of quinoline has been provided in this paper. The synergism factor decreases when the reaction temperature increases (280-340 degrees C). The synergetic effect leads to improve the hydrogenation activity for the stacked bed compared with the single Mo/gamma-Al2O3 bed, which may be attributed to the generation of hydrogen spillover on the Ni/gamma-Al2O3 catalyst.
