Abstract
A corona discharge pollutant destruction system has two or more corona discharge reactors in series, with each stage optimized for either oxidation of hydrocarbons (HC) and carbon monoxide (CO) or reduction of nitrogen oxides (NO.sub.x). The reactors may be arranged with initial oxidation stages followed by reduction stages. Alternatively, the oxidation and reduction reactors may be arranged in alternate stages, with each oxidation reactor followed by a reduction reactor. The treatment of different pollutants by different reactors is achieved by supplying the different reactors with different power levels.
