建立了甲烷介质阻挡放电的一维流体模型。该模型描述了控制甲烷转化为高级碳氢化合物过程的气相化学。讨论了各种等离子体的空间平均密度随时间的变化规律。给出了甲烷转化率和反应产物产率随反应器停留时间的变化规律，并与实验数据进行了比较。高碳氢化合物(C(2)H(y)和C（3)H(y)）和氢气通常是重要的反应产物。此外，确定了主要的潜在反应途径。
A one-dimensional fluid model for a dielectric barrier discharge in methane, used as a chemical reactor for gas conversion, is developed. The model describes the gas phase chemistry governing the conversion process of methane to higher hydrocarbons. The spatially averaged densities of the various plasma species as a function of time are discussed. Besides, the conversion of methane and the yields of the reaction products as a function of the residence time in the reactor are shown and compared with experimental data. Higher hydrocarbons (C(2)H(y) and C(3)H(y)) and hydrogen gas are typically found to be important reaction products. Furthermore, the main underlying reaction pathways are determined.
