It was found that Pd-Co/active carbon catalyst was the optimal catalyst, and Pd-Co/γ-Al2O3 was also good, but silica and kieselguhr were not proper carriers for the object reaction, because of their stronger surface acidity, which could result in the formation of polymer, jammed the micro pores of catalyst, and then resulted in its deactivation. Addition of Bi, Ce and Cu promoters could not improve the activity of catalyst, but La and Ba promoter could enhance the activity of catalyst apparently, and the Co was the best promoter, especially Co was impregnate in advance. It was attributed to that the pre-impregnated Co may occupy the micro pores of active carbon, and cover some bad functional groups on the surface of catalyst, so that the active and selectivity of catalyst could be enhanced obviously.

研究结果表明，Pd-Co/活性炭催化剂是目标转移加氢反应的最适宜催化剂，Pd-Co/γ-Al203效果也较好，而硅胶和硅藻土由于表面酸性较强，容易造成生成聚合物而堵塞催化剂微孔、使催化剂迅速失活；此外，添加Bi、Ce、Cu等助剂时对活性并无改善作用，而添加La和Ba助剂时可使Pd的催化活性有所提高，效果最好的是Co助剂，尤其是先浸渍Co的Pd-Co/C催化剂，原因是Co占据了活性炭的微孔、覆盖了某些对目标反应不利的官能团，使其活性和选择性都有较大幅度的提高。
