| 摘 要： | 以Hβ和Ce-β为载体，采用等体积浸渍法制备了Pd/Hβ和Pd/Ce-β催化剂(1%，质量分数)。以含5.0%(质量分数)苯酚的水溶液作原料，考察了该催化剂在苯酚水相加氢脱氧(HDO)反应中的催化性能。研究发现，苯酚水相HDO反应中环己酮加氢生成环己醇的反应是速率控制步骤，双环产物主要源于中间产物环己酮与环己醇的烷基化反应。Ce的引入可提高Pd催化剂的HDO活性，促进催化加氢活性，而抑制烷基化反应。

| Abstract: | Pd/Hβ and Pd/Ce-β (1%, mass fraction) were prepared by the incipient impregnation method. Their catalytic performances in aqueous-phase hydrodeoxygenation (HDO) of phenol were investigated with a model fuel containing 5.0% (mass fraction) phenol in water as raw material. It was found that the hydrogenation of cyclohexanone to cyclohexanol was the rate-determining step in the aqueous-phase HDO of phenol. Bi-cyclohexane was generated from the alkylation of cyclohexanone with cyclohexanol. Pd/Ce-β showed higher HDO activity than Pd/Hβ, meaning that Ce modification of β can enhance the hydrogenation activity and suppress the alkylation reactivity of the Pd supported catalyst. |
