Abstract—

Studies of the composition of the products of chemical reactions in the afterglow of a new type of atmospheric discharge, the microwave self-non-self-sustained discharge in air with admixtures of methane, were carried out. A detailed kinetic model was developed that describes the kinetics of reactions with polyatomic nitrogen oxides at the stage of intensive cooling of the discharge channel. It was found that the formation of nitrogen oxide NO depends on the percentage of the products of the methane molecule dissociation in the nitrogen–oxygen mixture that, initially, is atomic. The new discharge type can be used for the plasmachemical processing of gaseous media.

空气中亚阈值微波放电冷却阶段与甲烷混合物形成氮氧化物的模拟

摘要-

研究了一种新型大气放电，即混合有甲烷的空气中微波自非自持放电余辉中化学反应产物的组成。开发了一个详细的动力学模型，该模型描述了在排放通道的强烈冷却阶段与多原子氮氧化物的反应动力学。发现氮氧化物 NO 的形成取决于最初是原子的氮氧混合物中甲烷分子解离产物的百分比。新型放电型可用于气态介质的等离子化学处理。
