CO2 reforming of CH4 by atmospheric pressure abnormal glow plasma

A novel plasma atmospheric pressure abnormal glow discharge was used to investigate synthesis gas production from reforming methane and carbon dioxide. Special attentions were paid to the discharge characteristics and CH4, CO2 conversion, H-2, CO selectivity, and ratio of H-2/CO varied with the changing of discharging power, the total flux, and the ratio of CH4/CO2. Experiments were performed in wider operation variables, the discharging power of 240 to 600 W, the CH4/CO2 of 0.2 to 1.0 and the total flux of 140 to 500 mL/min. The experiments showed that the conversion of CH4 and CO2 was up to 91.9% and 83.2%, the selectivity of CO and H-2 was also up to 80% and 90% and H-2/CO mole ratio was 0.2 to 1.2, respectively. A brief analysis for discharge characteristics and the experimental results were given.
