At ambient pressure and temperature direct conversion of methane to ethylene , acetylene and synthetic gas corona discharge plasma is presented. The process was carried out using a quartz reactor of outer diameter of 9 millimeter and an ac current corona gas discharge of 50-hertz.the rate of methane conversion was as high as 63% with high selectivity to more valued products. the products were mainly C2 hydrocarbons where the share of COx GASES was minor. the total yield to C2 products was 39% . the energy efficiency was more than 0.22 mmol/kj.
