Proposal Number: ECS-9632384 Principal Investigator: Shirshak Dhali/Southern Illinois University at Carbondale Title: Dual pressure discharge for non-thermal plasma at atmosperic pressure Abstract In this research a novel discharge for the production of non-thermal plasmas in air at atmospheric pressures will be investigated. The design consists of two dielectric barrier discharges separated by a UV transparent dielectric. The UV photons pre-ionizes the pressure chamber. The resulting Avalanches in the high pressure region produce a diffused (Townsend-like) discharge. The UV irradiation is timed and efficiently coupled to the atmospheric pressure discharge. The eventual application of this research is in air pollution control. The electrical properties of the discharge (onset voltage, power, average current, etc.) will be characterized for this goal. The OH radical production, which is thought to be the most important radical for oxidation applications, will be investigated using laser induced fluorescence in an air discharge; and the dual pressure discharge will be investigated for its potential to remove SO2 by oxidation in a coal combustion flue gas. _________________________________________________________________

提案编号：ECS-9632384首席研究员：Carbondale的Shirshak Dhali/Shirshak Dhali/Southern Illinois University in Carbondale标题：在这项研究中，在大气压压力下生产非热压力的非热压摘要的非热压力摘要的双压排放。该设计由两个介电屏障放电组成，该介电屏障放电被UV透明介电分隔。 紫外线光子预先引入压力室。 高压区域中产生的雪崩产生了扩散的（汤森状的）排放。 紫外线照射是定时并有效耦合到大气压排放的。 这项研究的最终应用是在空气污染控制中。该目标将为排放的电气特性（发作电压，功率，平均电流等）进行特征。 OH自由基生产被认为是氧化施用最重要的自由基，将在空气放电中使用激光诱导的荧光进行研究。并将研究双重压力排放，以通过在煤燃烧气体中氧化去除SO2的潜力。 __________________________________________________________________________
