摘要：

在阐述火花放电机制与等离子体特性基础上，着重探讨了火花放电的电极结构与等离子体反应器。新研制的电极旋转的新型 kHz 交流火花放电反应器，在甲烷裂解制乙炔和甲烷与二氧化碳重整制合成气应用研究中，其放电稳定性、反应物转化率、产物浓度和能量效率等指标，均明显优于其它放电反应器。

Abstract:

Based upon demonstrating the discharge mechanism and plasma characteristic of spark discharge, electrode configuration and plasma reactor of spark discharge were discussed especially. A novel kHz AC spark discharge reactor with rotating electrode, developed in our group, was applied in methane pyrolysis to produce acetylene and reforming of methane with CO₂ to produce syngas. Its discharge stability, reactant conversion, product concentration and energy efficiency are higher obviously than those of other discharge reactors.
