Abstract
The subject invention is a commercial device to effectively remove NOx and other pollutants from an exhaust gas stream. Microwave enhancement of oxidation/reduction catalysis is selectively employed as the exhaust gas stream traverses a bed of catalyst particles, which may operate as either a fixed or fluidized bed. An unique feature involves the conventional, non-microwave, conversion of NO to NO.sub.2 ; however, the subsequent reaction of reducing NO.sub.2 is microwave enhanced.
