摘要
研究了Ｐｔ／Ａｌ＿２Ｏ＿３催化剂在丁二烯二聚体脱氢制乙苯反应的反应性能，考察了反应温度、反应压力、空速以及原料配比等工艺条件对反应的影响。结果表明，经焙烧处理过的Ｐｔ／Ａｌ＿２Ｏ＿３催化剂对所研究的反应具有比较稳定和有效的催化作用，可使转化率保持在８０％、乙苯的选择性保持在９２％以上，反应温度和空速对反应影响较大，宜取３５５℃和０．６ｈ￣（－１）。
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.
