Ethene, a key commodity chemical in manufacturing diverse consumer products, can be produced through oxidative dehydrogenation of ethane to reduce carbon emissions, but requires catalysts with improved selectivity. Recent advancements in catalytic technologies and CO2-assisted ethane dehydrogenation offer opportunities for economically feasible processes.
Ethene is a commodity chemical of great importance for manufacturing diverse consumer products, whose synthesis via crude oil steam cracking is one of the most energy-intensive processes in the petrochemical industry. Oxidative dehydrogenation (ODH) of ethane is an attractive, low energy, alternative route to ethene which could reduce the carbon footprint for its production, however, the commercial implementation of ODH requires catalysts with improved selectivity. This review critically assesses recent developments in catalytic technologies for ethane ODH, and discusses how insight into proposed mechanisms from computational studies, and CO2 assisted ethane dehydrogenation (CO2-DHE), provide opportunities for economically viable processes to meet growing demands for ethene while reducing carbon emissions. Future trends and emerging technologies for ethane ODH are also discussed.
