An uncatalyzed process for converting gaseous nitric oxide (NO) present in a flue gas or an exhaust gas to molecular nitrogen and water at a relatively low temperature (e.g. 250-300 DEG C) comprises: contacting the exhaust gas with one or more reagents (e.g. aqueous hydrogen peroxide) which, via reaction with the nitric oxide, lead(s) to the formation of nitrous acid (HONO) in the gas phase; and then contacting the resulting gaseous mixture with ammonia or a compound which under the prevailing conditions liberates ammonia. |
