摘要: A process for removing nitrogen oxides from exhaust gases which comprises;Introducing an oxidizing gas into the exhaust gas to oxidize the nitrogen monoxide contained therein to nitrogen dioxide and thereby form a first oxidized exhaust gas;Irradiating said first oxidized gas with actinic light to oxidize said nitrogen dioxide to nitric acid and thereby form a second oxidized exhaust gas; andRemoving said nitric acid from said second oxidized exhaust gas.
