Abstract	Describes a novel catalytic route for the oxidative dehydrogenation of ethane to ethylene in the presence of HCl at moderate temperatures. Researchers observed CeO2 to be the most efficient catalyst for the production of ethylene from the variety of metal oxides examined in this work. CeO2 nanocrystals with rod and cube morphologies exhibited higher ethane conversions and ethylene selectivities than CeO2 nanoparticles. The modification of CeO2 by MnOx increased catalytic performance. The catalyst was stable and the ethylene yield could be sustained at 65%–70% over 100 hours of reaction. The presence of HCl played a key role in the selective production of C2H4. Some of the C2H4 was probably formed from chloroethane by dehydrochlorination.
