Ethylbenzene Dehydrogenation with CO₂ over V₂O₅-Fe₂O₃/Al₂O₃-TiO₂ Catalyst

Abstract:

The oxidative ethylbenzene dehydrogenation to styrene with CO₂ has been studied using various catalysts to enhance its activity and stability. The type of V₂O₅-Fe₂O₃/A_l2O₃-TiO₂ catalyst is studied to fit for this process. It is found that different TiO₂ loadings can lead to the activity difference. Compared with the results happened in N₂ atmosphere, both activity and selectivity were lower than that in the CO₂. Hence, CO₂ was chosen as a soft oxidant by improving activity and selectivity in the process of oxidative ethylbenzene dehydrogenation to styrene with CO₂ over the investigated catalysts.
