Promotional Effect of Cr on Catalytic Performance of Fe/γ-Al2O3 for Ethylbenzene Dehydrogenation in the Presence of N2O
This work shows that N2O, which causes global warming, could be effectively utilized as a soft oxidant in the oxidative dehydrogenation of ethylbenzene over alumina-supported iron oxide catalysts. The modification of the catalytically active iron oxide component with appropriate amounts of chromium oxide led to higher styrene yield (48.1%) with high styrene selectivity ( > 90%) at 500 °C and suppressed the catalyst deactivation for EB dehydrogenation under N2O. The improved catalytic behavior was attributed to the enhanced dispersion and redox properties of iron active species.
