Abstract
NO.sub.x is removed from flue gases by contacting same in the presence of active coke/active carbon and a reducing agent, e.g. NH.sub.3, CO or H.sub.2. According to the invention, the adsorbent is precharged with the reducing agent, thereby increasing the surface area over which the adsorbent can react with the flue gas and decreasing the levels of gas-reducing agent which must be used and which may appear in the cleaned gas.
