主　　题：methane C2 hydrocarbons plasma 

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