Conversion of natural gas to C2 hydrocarbons via cold plasma technology

摘要: Abstract The plasma technology served as a tool in unconventional catalysis has been used natural gas conversion, because the traditional catalytic methane oxidative coupling reaction must be performed at high temperature on account of stability molecule. focus this research is to develop process converting C2 hydrocarbons with non-equilibrium room and atmospheric pressure. It was found that conversion increased selectivity decreased voltage. optimum input voltage range 40-80 V corresponding yield hydrocarbons. Methane inlet flow rate methane. proper 20-40 ml/min (corresponding residence time 10-20 s). experimental results show 47% 40% under condition using DBD cold technology. breakdown VB determined by type electrode discharge gap width glow reactor. VB, min derived from Paschen law equation established.
