摘要:

在常温常压下采用新型旋转电极等离子体反应器,对辉光等离子体作用下的甲烷偶联反应制C2烃进行了研究。结果表明,甲烷偶联反应的主要产物为C2H2,占C2烃的80%以上,能量效率在5.6%~11.2%之间;增加H2含量可以提高CH4转化率和C2烃收率;在500~2200kJ•mol−1的能量密度范围内,CH4转化率随能量密度的增大而线性增加,C2烃收率随着能量密度的增加呈峰形变化趋势。

Abstract:

At normal temperature and pressure, glow discharge plasma was used as a new method for the coupling of methane to hydrocarbons by a new type plasma reactor with rotary electrode. On the experimental scale, the results showed that C2H2 is more than 80% in C2 hydrocarbons formation and energy efficiency is 5.6% to 11.2%. With increasing of the amount of hydrogen, the CH4 conversion and the yield of C2 hydrocarbons were increased. As the energy density increased from 500 to 2200 kJ•mol−1, CH4 conversion increased linearly and C2 yield changes with a peak-shape curve.

Key words: Rotary electrode, Glow plasma, Methane coupling, C2 hydrocarbons, Energy efficiency
