Abstract
The ways of targeted design of effective nanocomposite catalysts based on metal oxide systems and zeolites, in particular BEA type, for the processes of dry/super-dry conversion of methane/biogas for the obtaining of hydrogen and syngas with adjustable H2/CO ratio as well as oxidative dehydrogenation of C3-C4 alkanes with the participation of CO2 producing valuable olefins and dienes are considered. Isolated metal cations/small clusters exhibit higher activity, selectivity, and stability when compared to bulk structures in alkane dehydrogenation reactions since their activation involves the participation of coordinatively unsaturated metal cations on anionic vacancies. This can serve as a scientific basis for the targeted development of highly active and stable catalysts for such processes.
