Abstract

Abstract: Methane coupling to produce C₂ hydrocarbons was studied with a newly developed rotary helix electrode in glow discharge plasma at atmospheric pressure. Effects of peak electric voltage and feed flow rates of methane and hydrogen on CH₄ conversion, C₂ yield, and the selectivity were investigated using copper or stainless steel electrode. 69.85% of C₂ single process yield, 70.46% of CH₄ conversion, and 99.14% of C₂ selectivity were obtained at optimized conditions.

Key words: Glow discharge plasma, Rotary helix electrode, Methane, C₂ hydrocarbons
