Abstract

Det beskrives en fremgangsmåte for oksidasjon av ammoniakk, inkludert Adrussow-prosessen, hvor en blanding omfattende luft og ammoniakk bringes i kontakt med en ammoniakk-oksidasjonskatalysator av edelmetall og den resulterende gassblandingen bringes i kontakt med en katalysator som er effektiv for dekomponering av dinitrogenoksid, karakterisert ved at før gassblandingen bringes i kontakt med katalysatoren som er effektiv for dekomponeringen av dinitrogenoksid, så bringes gassblandingen i kontakt med et beskyttelsesmateriale. Beskyttelsesmaterialet beskytter dinitrogenoksid-ekomponeringskatalysatoren mot avsetning av edelmetall og/eller katalysatorforgiftning. I en foretrukken utførelsesform fungerer katalysatoren som er effektiv for dekomponering av dinitrogenoksid som en ammoniakk-oksidasjonskatalysator.A process for oxidation of ammonia is disclosed, including the Adrussow process, in which a mixture comprising air and ammonia is contacted with a noble metal ammonia oxidation catalyst and the resulting gas mixture is contacted with a catalyst effective for decomposition of nitrous oxide, characterized by contacting the gas mixture with the catalyst effective for the decomposition of nitric oxide, the gas mixture is contacted with a protective material. The protective material protects the nitrous oxide composition catalyst from the deposition of precious metal and / or catalyst poisoning. In a preferred embodiment, the catalyst which is effective for decomposing nitrous oxide acts as an ammonia oxidation catalyst.
