Plasma-catalytic CO2 hydrogenation to ethane in a dielectric barrier discharge reactor

Anthropogenic greenhouse gas emissions have caused changes to the Earth’s climate, resulting in catastrophic weather events that are becoming more frequent and intense. Developing carbon-neutral processes for CO2 conversion powered by renewable energy is one way of attaining a circular economy, as waste converted new carbon-containing product, without also being created by-product during process. Plasma-catalysis gaining increasing interest utilisation under mild conditions, particularly green chemicals fuels using hydrogen, this electrified process can easily be combined with clean ensure Previous studies mainly focussed on production methane from H2; however, ethane (C2H6) much valuable product. In work, we report non-thermal plasma-catalytic into C2H6 dielectric barrier discharge (DBD) reactor. The influence variety alumina-supported metal catalysts (Ru, Cu, Ni Fe) hydrogenation was evaluated. Ru catalyst attained highest selectivity towards C2H6, at almost 40%. increased efficiency around 18%, comparison plasma reaction pure alumina (12%). achieved H2 29%. Plasma-assisted promising via conversion.
