ABSTRACT:
An improved process for SNCR of NO.sub.x is provided. The exhaust gases from a combustion source are fed to a reducing reactor. A NO.sub.x reductant is injected into the exhaust to form a mixture. The mixture is then heated by regenerative heating to effect NO.sub.x reduction reactions. The reacted exhaust may then be further heated to remove byproducts, such as N.sub.2 O, and unreacted reductant.
