Oxidative Transformations of Ethane and Ethylene on VMoTeNbO Catalysts

Abstract

Comparative studies of oxidative transformations of ethane and ethylene were performed on multi-component oxide catalysts of the preset cationic composition, V0.3Mo1Te0.23Nb0.12, differing in the final calcination temperature. The highest (∼74%) ethylene yield in oxidative dehydrogenation of ethane is reached on the catalysts calcined in the temperature interval 550–650°C, which is due to the formation of the maximal amount of the active M1 phase.
