Abstract
Selektiv katalytisk reduksjon av nitrogenoksidet til nitrogen bevirkes ved å omsette nitrogenoxid, nitrogendioksid eller en blanding derav med et reduksjonsmiddel som består av en alifatisk karaboksylsyre med 1-5 karbonatomer ved en temperatur som spenner fra ca. 250 til ca. 600°C, i nærvær av en katalysator som omfaner et metalloksid hvilket utvelges fra den gruppe som består av vanadiumoksid, kopperoksid, nikJceloksid og jemoksyd, idet katalysatoren bæres på en porøs bærer. Fremgangsmåten i folge oppfinnelsen gjør det mulig i det vesentlige å fullstendig redusere N0¿ til harmløst N, på en effektiv, miljømessig gunstig og kostnadseffektiv måte. CONVERTER LUFT BRENSEL UTSLIPP TIL '^^TURLIC MILJØ VARMEVEKSLERSelective catalytic reduction of the nitric oxide to nitrogen is effected by reacting nitric oxide, nitrogen dioxide or a mixture thereof with a reducing agent consisting of an aliphatic carboxylic acid having from 1 to 5 carbon atoms at a temperature ranging from ca. 250 to approx. 600 ° C, in the presence of a catalyst which embraces a metal oxide selected from the group consisting of vanadium oxide, copper oxide, nickel oxide and iron oxide, the catalyst being supported on a porous support. The process of the present invention essentially allows to completely reduce the NO to harmless N, in an efficient, environmentally beneficial and cost effective manner.
