摘要
The platinum catalyst supported on carbon covered γ-Al 2O 3(CCA) or γ-Al 2O 3 with K 2O as assistant was prepared and used for preparation of o-phenylphenol(OPP) by dehydrogenation of 2-cyclohexenyl- cyclohexanone. The catalyst was pre-poisoned with CS 2 to improve its catalytic activity. The results showed that the catalytic performance of Pt supported on CCA is better than that supported on γ-Al 2O 3. When the catalyst consists of \[ω(Pt)=0.5%, ω(K 2O)=1%\]/CCA\ and m(CS 2)∶m(Pt) is 1.0∶100, the selectivity of OPP was more 96% in a reaction condition of 350 ℃ and flow rate of H 2 at 60 mL/min.
