Abstract

Comparative studies of oxidative transformations of ethane and ethylene were conducted on multi-component oxide catalysts of the preset cationic composition, V 0.3Mo 1Te 0.23Nb 0.12, differing in the final calcination temperature. At 400°С in the reaction mixture with the hydrocarbon:oxygen ratio of 1 : 1, all the synthesized catalysts were more active in oxidative dehydrogenation of ethane than in oxidation of ethylene. The catalyst calcination temperature determining the qualitative and quantitative phase composition influenceD the ratio of the overall ethane and ethylene transformation rates. The highest ethylene yield in oxidative dehydrogenation of ethane was attained on the catalysts calcined in the temperature interval 550°C - 650°C, which is due to the formation of the maximal amount of the active M1 phase.
