Kinetic modeling of plasma methane conversion using gliding arc

Abstract

Plasma methane conversion in gliding arc discharge was studied. The effect of total gas flow rate and input frequency refers to power consumption was examined to evaluate the performance of gliding arc plasma system and the reaction mechanism of decomposition. The maximum conversion of methane reached 50% at the total gas flow rate of 1 L/min. The plasma reaction occurred at 1 atm and the main products were C (solid, hydrogen, and acetylene. The plasma of methane conversion was exothermic reaction, which increased the product stream at ∼ 30°-50°C. Increasing input power could produce more conversion of methane and produce more energy from plasma reaction.
