The methane conversion into C₂ hydrocarbons, carbon black, and hydrogen has been studied under non-equilibrium plasma conditions, using dielectric barrier discharges (DBD) and gliding discharges (GD) at low and medium temperatures at atmospheric pressure. It has been found that ethane is the main product of the filamentary DBD action in the mixtures CH₄+Ar and the reaction rate depends mainly on the concentration of high-energy components being able to initiate the chemical transformations of methane. Using GD, two processes are observed: the methane conversion into unsaturated hydrocarbons C₂ (mainly acetylene) and into carbon black. The energy density of GD and the methane concentration in initial gas mixtures (CH₄+H₂ and CH₄+Ar) are the main parameters influencing the methane conversion rate and the unit energy consumption.
