Abstract

The conversion of CO₂ and CH₄ into value-added chemicals is studied in a new geometry of a dielectric barrier discharge (DBD) with multi-electrodes, dedicated to the treatment of high gas flow rates. Gas chromatography is used to define the CO₂ and CH₄ conversion as well as the yields of the products of decomposition (CO, O₂ and H₂) and of recombination (C₂H₄, C₂H₆ and CH₂O). The influence of three parameters is investigated on the conversion: the CO₂ and CH₄ flow rates, the plasma power and the nature of the carrier gas (argon or helium). The energy efficiency of the CO₂ conversion is estimated and compared with those of similar atmospheric plasma sources. Our DBD reactor shows a good compromise between a good energy efficiency and the treatment of a large CO₂ flow rate.
