Dehydrogenation of ethylbenzene over iron oxide

Table 1 gives some basic parameters corresponding to the production of styrene via steam process and CO 2 process. In the presence of CO 2 the temperature of the dehydrogenation was assumed to be 50 K lower than that for commercial process on the basis of equilibrium styrene yield shown in Fig. 2.
