| Abstract: | The reaction properties of Pt/Al_2O_3 in the dehydrogenation of ethylbenzene was studied andthe technological conditions such as reaction temperature,pressure,LHSV and diluent amountwere examined. The results show that the improved Pt/Al_2O_3 catalyst possesses stable and effective properties.The conversion of vinyl cyclohexene and selectivity of ethylbenzene can be main-tained over 80%and 92%respectively after 100 hours of reaction. The reaction temperature andLHSV of vinyl cyclohexene are the more important factors which are suggested.to take the valuesof 355℃ and 0.6h￣(-1) respectively. |
