在过去的大约十年里，常压非热等离子体作为一种技术在减少污染领域得到了越来越多的推广。在这种等离子体中，与离子、原子和分子相比，电子的温度要高得多。本文对涉及的技术和不同的潜在应用领域进行了概述。根据这些等离子体内发生的过程的性质，给出了这些大气等离子体的一般描述以及破坏或去除气相污染物所涉及的基本原理。描述了一些不同的等离子体技术的例子。所描述的技术包括脉冲电晕、微波和介质阻挡等离子体。讨论了它们在焚烧炉尾气处理、工业过程尾气处理和柴油机尾气后处理等领域的适用性和应用。还讨论了如何使用物理和化学过程建模来预测系统性能，并将其作为确定系统大小以满足客户要求的工具。
For approximately the past ten years, atmospheric pressure non-thermal plasmas have been increasingly promoted as a technology for a number of applications in the area of pollution abatement. In such plasmas, the electrons have a significantly higher temperature compared to the ions, atoms and molecules. This paper provides an overview of both the technologies involved and the diverse potential application areas. A general description of these atmospheric plasmas and the basic principles involved in the destruction or removal of gaseous phase pollutants, based on the nature of the processes taking place within these plasmas, are given. A number of examples of the different plasma technologies are described. The technologies described are pulsed corona, microwave and dielectric barrier plasmas. Their suitability and use in various application areas are also discussed including incinerator off gas treatment, industrial process off gas treatment and diesel exhaust aftertreatment. The use of modelling of the physical and chemical processes involved to predict system performance and as a tool for sizing systems to meet customer requirements is also discussed.
