Abstract

Abstract: Dehydrogenation of ethylbenzene to styrene under CO2 was investigated over the activated carbon-supported iron catalyst with a Li promoter (Fe-Li/AC). The addition of Li greatly improves the catalytic activity of Fe/AC and the coupling effect of CO2 and suppresses the catalyst deactivation for EB dehydrogenation under CO2.

Key words: promoter, lithium, carbon dioxide, iron, activated carbon, ethylbenzene dehydrogenation, styrene, coupling reaction
