Oxidative Dehydrogenation of Ethane over Ce-based Monolithic Catalysts using CO2 as Oxidant
Highly active Ce-based monolithic catalysts for oxidative dehydrogenation of ethane with CO2 were prepared and characterized by various techniques. The high oxidation state Ce4+ species had higher catalytic activity than the Ce3+ species in the monolithic catalysts. The Ce4+ species was reduced to Ce3+ species in the ethane dehydrogenation process, and the reduced Ce species was reoxidized to the Ce4+ species by treatment with CO2 at 750 C, the Ce redox cycle played an important role in the catalyst's high activity.
