摘要: 利用自制等离子体反应器开展电晕-介质阻挡协同放电降解连续流丙酮研究，利用均匀设计法获得适宜的丙酮降解参数及其相互关联性，通过解析电晕-介质阻挡协同放电机理，结合丙酮降解热力学性能分析，获得影响丙酮降解的主要因素。结果表明：丙酮降解的适宜条件为反应器电压9.60 kV、空气流量1.4 L·min-1、在丙酮气体流量20 mL·min-1的连续流体系下，电晕-介质阻挡协同放电3 min、初始质量浓度为1.807 mg·L-1的丙酮单次循环降解率可达35.01%。解析等离子体放电过程和热力学性质发现，丙酮降解受协同放电活性粒子与反应温度的双重影响。

Abstract: A homemade plasma reactor is designed for acetone degradation through corona dielectric barrier co-discharge in a continuous flow. The operation conditions for acetone degradation were carefully optimised using a uniform design method. The results show that the acetone degradation rates could reach 35.01% with the initial concentration of 1.807 mg·L-1, and under an acetone and air gas flow of 20 mL·min-1and 1.4 L·min-1 ,respectively. The corona media barrier co-discharge was carried out for 3 min under 9.60 kV. The factors that induce the acetone degradation are identified based upon the studies on the mechanism of corona dielectric barrier co-discharge and thermodynamic analysis. It concludes that both corona dielectric barrier co-discharges and reaction temperature could affect the degradation of acetone.
