CO2 reforming of CH4 to syngas (H2 and CO) has emerged as one of the attractive options for mitigating carbon emissions. Here, a water-cooled dielectric barrier discharge plasma reactor has been constructed for CO2–CH4 reforming to produce syngas and value-added chemicals. The effects of the main parameters (i.e., discharge power, CH4/CO2 molar ratio, and gas flow rate) on CO2–CH4 reforming were investigated. The highest conversion rate of CH4 and CO2 was found to be 40.57% and 27.15%, respectively, with CO and H2 selectivity of 56.07% and 43.71%, respectively. The total energy efficiency achieved was 0.28 mmol/kJ. C2H6 was found to be the main hydrocarbon product. Lastly, the mechanism of CO2–CH4 reforming was proposed in terms of the active species and products.
