Process for separating nitrogen oxides from gases, in particular from fumes
Abstract
Abstract Translated from German Bel unserem Verfahren zur Abscheidung von NO X aus Gasen, insbesondere Rauchgasen. bei dem das NO X aus dem Rauchgas an einem festen Adsorptionsmittel, insbesondere Aktivkohle/Aktivkoks. unter Zugabe eines Reduktionsmittels, insbesondere Ammoniak, CO, Wasserstoff, katalytisch abgetrennt wird und bei dem das Adsorptionsmittel mehrmals hintereinander mit dem zu entstickenden Gas in Kontakt gebracht wird, ist zur weiteren NO x -Minderung vorgesehen, daß das Adsorptionsmittel mit zumindest einem Anteil an Reduktionsmittel vorbeladen und danach mit dem zu entstickenden Gasstrom in Berührung gebracht wird. Bel our process for the separation of NO X from gases, especially flue gases. in which the NO x from the flue gas on a solid adsorbent, especially activated carbon / activated coke. with the addition of a reducing agent, in particular ammonia, CO, hydrogen, is catalytically separated and in which the adsorbent is brought into contact with the gas to be denitrated several times in succession, it is provided for further NO x reduction that the adsorbent contains at least a proportion of reducing agent preloaded and then brought into contact with the gas stream to be denitrified.
