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。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.
