| 摘 要： | 研究了助剂Li对CO2气氛下活性炭负载的Fe氧化物(Fe/AC)催化剂上的乙苯脱氢性能的影响和CO2的作用。助剂Li的添加提高了Fe/AC催化剂在CO2气氛下的乙苯脱氢活性和稳定性;CO2气氛下的苯乙烯收率明显高于N2气氛下,表明CO2显著促进了乙苯脱氢反应。

| Abstract: | The effect of Li oxide on activated carbon supported iron catalysts(Fe/AC) and the role of CO_2 in the dehydrogenation of ethylbenzene were investigated.The addition of promoter Li to Fe/AC catalyst affords a significant promotion in catalytic activity and stability.The styrene yield for the ethylbenzene dehydrogenation in the presence of CO_2 is higher than that in the presence of N_2,indicating that CO_2 markedly promotes the dehydrogenation of ethylbenzene. |
