Oxidative Dehydrogenation of Ethane in the Presence of СО2 on CrOx/SiO2 Catalysts

The oxidative dehydrogenation of ethane in the presence of CO2 was studied on SiO2-supported chromium oxide catalytic systems with different texture characteristics. The highest activity was displayed by the samples deposited on SiO2 with a high specific surface area. On the 5%CrОх/SiO2 catalyst, the ethylene selectivity was ~80% at ~50% conversion of ethane. The results of our physicochemical analysis showed that the catalyst activity depended on the content of Cr(VI) particles, whose formation depended on the nature of support.
