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。The effect of Li oxide on activated carbon supported iron catalysts （Fe/AC） and the role of CO2 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 CO2 is higher than that in the presence of N2, indicating that CO2 markedly promotes the dehydrogenation of ethylbenzene.
