Title: Non-thermal plasma apparatus utilizing dielectrically-coated electrodes for treating effluent gas

Abstract: An improved non-thermal plasma apparatus for treating NO.sub.x bearing gas streams has a plasma reactor and an inlet and outlet. The plasma reactor is equipped with a plurality of dielectrically-coated electrodes between which a selected voltage is applied to generate a non-thermal plasma environment for driving selected electrochemical reactions. A predefined voltage is applied across the electrodes to create microdischarges in the exhaust gas stream to convert nitric oxides into primarily nitrogen dioxides. At least a portion of the gas is diverted through an ethanol bath before entering the reactor. The dielectric is preferably a fluoropolymeric substance.
