Abstract
An Fe2O3 (10 wt%)/Al2O3 (90 wt%) catalyst prepared by a coprecipitation met
hod was found to be effective for dehydrogenation of ethylbenzene to produc
e styrene in the presence of CO2 instead of steam used in commercial proces
ses. The dehydrogenation of ethylbenzene over the catalyst in the presence
of CO2 was considered to proceed both via a one-step pathway and via a two-
step pathway. CO2 was found to suppress the deactivation of the catalyst du
ring the dehydrogenation of ethylbenzene.
