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 CH;, CO;conversion, H;, CO selectivity, and ratio of H;/CO varied with the changing of discharging power, the total flux, and the ratio of CH;/CO;. Experiments were performed in wider operation variables, the discharging power of 240 to 600 W, the CH;/CO;of 0.2 to 1.0 and the total flux of 140 to 500 mL/min. The experiments showed that the conversion of CH;and CO;was up to 91.9% and 83.2%, the selectivity of CO and H;was also up to 80% and 90% and H;/CO mole ratio was 0.2 to 1.2, respectively. A brief analysis for discharge characteristics and the experimental results were given.
