Catalytic Dehydrogenation over Pd-Supported ZSM-5 Zeolite for o-Phenylphenol Synthesis
Abstract:
Pd-supported ZSM-5 zeolites prepared through ion exchange technique were used as a dehydrogenation catalyst for synthesis of o-phenylphenol from cyclohexanone. When Si/Al ratio in the catalyst was 85:1 or more, an obvious reduction in attenuation rate of catalyst activity was observed. When the Si/Al ratio was of 17:1 or less, polymer compounds could be formed on the surface of zeolite, that would decrease the dehydrogenation activity due to the reduction of the specific surface area of the catalyst.
