The peculiarities of propane dehydrogenation with carbon dioxide over zeolite catalysts of different structural types, in particular, BEA with incorporated Zn, Ga (Ta, Nb) heteroelements have been analyzed. The role of CO₂ as an oxidant, the effect of acid–base characteristics on propylene selectivity and yield, the stability of catalyst operation, and the routes of activation of reagents on acid–base sites of the surface are considered.
