Abstract:
Methane conversion into higher hydrocarbons has been investigated by non-thermal plasma. The most important advantages of utilizing this type of plasma are atmospheric pressure and ambient temperature of the operating system. Without any catalysts and with pure methane used as the feed gas, a stable 20 kilohertz spark discharge leads to an acetylene selectivity of 90.4 % with 54.5 % of methane conversion at a methane fow rate of 33 ml/min and a specific input energy of 54 kJ/L. Other components such as hydrogen, ethylene and ethane are also formed in the process as by-products. These remarkable results expose superiority of spark plasma in comparison with other types of non-thermal plasma
