摘要：
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. ©, 2015, Science Press.
