Materials and methods for oxidative dehydrogenation of alkyl aromatic compounds involving lattice oxygen of transition metal oxides

Abstract

In one aspect, the disclosure relates to a process for dehydrogenating a first dehydrogenation reactant into its unsaturated counterparts. The disclosed process comprises introducing a dehydrogenation reactant to a metal oxide catalyst having dehydrogenation activity, and dehydrogenating the dehydrogenation reactant to provide its unsaturated counterpart and hydrogen; selectively combusting the hydrogen released during dehydrogenation using a lattice oxygen from the metal oxide catalyst, resulting in a reduced metal oxide catalyst and steam; re-oxidizing the reduced metal oxide catalyst by introducing a gaseous oxidant to the reduced metal oxide catalyst; and optionally re-using the re-oxidized metal oxide catalyst for catalytic conversion and combustion. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
