摘要

<正> Plasma processes are among the emerging technologies for volatile organic compounds(VOC_s)abatement.Both thermal plasmas and non-equilibrium plasmas(cold plasmas)are beingdeveloped for VOC_s cleanup.Particularly,pulsed corona discharges offer several advantages overconventional VOC_s abatement techniques.To optimize the existing technology and to developit further,there is need to understand the mechanisms involved in plasma chemical reactions.Fur-thermore,it is strongly desirable to be able to predict the behavior of new VOC_s in non-equilibriumplasma environment from the data known for a few representative compounds.Pulsed corona dis-charge technique is introduced here with citation of relevant literature.Fundamental principles,useful for predicting the VOC_s'decomposition behavior,have been worked out from the publishedliterature.Latest developments in the area,targeted to minimize the energy losses,improve the VOC_sdestruction efficiency and reduce the generation of unwanted organic and inorganic by
