Abstract: (4782 Views)
Non-catalytic conversion of methane to ethylene and ethane was studied using non-equilibrium positive corona discharge at atmospheric pressure.The total selectivity for C2 hydrocarbons was more than 87% with a yield of 4.8% ethylene. The effect of voltage, temperature, and the ratio of methane to oxygen on methane conversion and selectivity of products at different levels are investigated. The experimental results indicate that the methane conversion increases with increasing the voltage applied to the electrodes. The methane conversion up to 300oC increases but above this temperature depend on feed ratio, it may increase or decrease. The highest methane conversion and C2 yield occures at CH4/O2 = 4/1.In a few experimets smale amounts of COX also was produced.
Keywords: Methane Conversion plasma, gas conversion corona discharge, Methane Non equilibrium plasma, Methane, non-thermal plasma
