Abstract:

It is a promising way for ethylene production by oxidative dehydrogenation of ethane. MoVTeNbO x catalyst has the advantages of high activity and strong redox ability, and it is currently the research focus of oxidative dehydrogenation of low carbon alkanes. In this work, the research progress of MoVTeNbO x composite metal oxide in the oxidative dehydrogenation of ethane to ethylene was systematically reviewed, including the crystalline phase structure and the active center of catalyst, the preparation of catalysts, influencing factors of catalytic conversion of ethane and the improvement of catalyst performance. The main research directions at present are the regulation strategy of the active center of polymetallic oxide catalyst, the optimization of the interactions among the oxides, optimizing the preparation conditions, improving the redox ability of the catalyst and the content of V5+ on the surface through the regulation of additives, and thus improving the oxidative dehydrogenation activity and operational stability, so as to provide the foundation for the large-scale production and industrial application of the catalyst. Finally, the development prospect of MoVTeNbO x mixed metal oxide in oxidative dehydrogenation is given.

Key words: ethane, oxidative dehydrogenation, ethylene, MoVTeNbO x mixed metal oxides
