Summary form only given, as follows. A dielectric barrier discharge (DBD) plasma reactor has been widely investigated for application to NO/sub x/ removal, VOC treatment, etc (1). The cylindrical and/or plane shapes are generally used as electrodes and dielectric barrier to produce microdischarges uniformly all over the reactor. However, the cylindrical and plane shapes causes a large pressure drop between the inlet and the outlet of the reactor because of the small cross section of the gas flow. This large pressure drop becomes a disadvantage for commercialization to the automobile industry, power plants, etc. The use of a multipoint electrode has some advantage against the plane one for a DBD reactor, 1) low pressure drop, 2) low dielectric power loss, 3) low voltage operation. We carried out NO/sub x/ removal from a 20 kVA diesel engine generator exhaust gas and its simulated gas using a DBD reactor for various electrode shapes.
