Beneficial Effect of Carbon Dioxide in Dehydrogenation of Ethylbenzene to Styrene over Zeolite-Supported Iron Oxide Catalyst

Abstract
In dehydrogenation of ethylbenzene with carbon dioxide over zeolite-supported iron oxide catalyst, ethylbenzene was predominantly converted into styrene by an oxidative manner. Carbon dioxide in this reaction played a role as an oxidant to greatly improve catalytic activity as well as coke resistance of catalyst.
