Nonthermal Plasma Processing for Air-Pollution Control: A Historical Review, Current Issues, and Future Prospects

Summary: This review describes the historical development, current status, and future prospects for nonthermal plasma (NTP) technology and its application as an air-pollution control. In particular, this review focuses on the cutting-edge technology of hybrid NTP, where it is combined with other methods such as wet processing, the use of adsorbents, and catalysis. Historical landmarks in the development of NTP technology and the current status of large-scale applications are discussed. The general characteristics of the combined system of NTP with catalysts are described in the context of the decomposition of NOx and benzene. Comparison of different NTP reactors for 200 ppm benzene decomposition (water vapor 0.5 vol.-%).
