| 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/A1 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. |
