Abstract
The present invention relates to a process for removing nitrogen oxides from gas streams such as furnace or utility boiler flue gas streams. An adsorber system is used to adsorb nitrogen oxides from the flue gas streams. An oxygen/ozone gas stream contacts the nitrogen oxides to convert the nitrogen oxides to N O which will exit the adsorber with the oxygen stream.
