The surface discharge-induced plasma chemical process (SPCP) has great advantages in the destruction of various gaseous pollutants (NO x, SOx, CO, Freons, etc.), air toxicants (Hg vapor, hazardous solvent vapors, etc.), and odors because of its unique features: a very strong decomposition capability for stable contaminant gases, its compact size, and its low cost. A ceramic-made reactor is used for generation of high-frequency surface discharge to produce a planar plasma region over its surface. The gas containing pollutants is contacted in this region and exposed to copious radicals (OH, O, O3 , N, NH2, NH, H, etc.) to be decomposed of or oxidized. This process has a very wide application range: from diesel engines, industrial furnaces, incinerators, and food processors to larger industrial boilers. The first application of SPCP was extremely small ozonizers with very high performance, but a number of new application fields are being developed
