混合放电臭氧发生的反应动力学模拟
Chemical Kinetics Simulation of Ozone Production Using Multi-discharge
摘要
Abstract
A chemical kinetics model, which was established based on plasma Perfectly Stirred Reactor of CHEMKIN, was used to simulate chemical kinetics of ozone generation using multi-discharge and to analyze sensitivity and rate of production.The simulation results show that the prediction agrees well with experimental data, and the ozone concentration increases with decreasing gas pressure, inlet gas temperature and oxygen gas rate.Proper increase of specific energy is benefit for ozone generation, but excessive specific energy show opposite behavior.In terms of reaction pathway of ozone production, O, O(1D) and O2(b1∑) are the most important species for ozone generation.The fact that the specific energy can't be too high are verified and explained from microcosmic chemical kinetics view again, because the effect of major reaction for generating ozone precursor O atom E+O2=＞O+O+E on ozone production decreases with increasing specific energy and temperature.In addition, the existences of O(1D), O2(b1∑) and excessive O are unfavorable for ozone generation.关键词
