Claims (5)
1. Fremgangsmåte for eksosgassetterbehandling av en eksosgass (31) som forlater en forbrenningsmotor (30), karakterisert ved at eksosgassen (31) blir ført over et roterende partikkelfilter (32) på en slik måte at eksosgass (31) strømmer rundt en del eller seksjon av filtermediet rotert inn i eksosgasstrømmen, og eksosgass (31) ikke strømmer rundt en del eller seksjon av filtermediet rotert ut av eksosgasstrømmen, der delen eller seksjonen av filtermediet rotert ut av eksosgasstrømmen blir fjernet fra et underkammer (34) av det det roterende partikkelfilteret (32) plassert utenfor eksosstrømmen der filtermediet blir separert fra sot- og askepartikler og/eller fra reaksjonsprodukter av sot- og askepartiklene med filtermediet via en separeringsanordning (36) utenfor det roterende partikkelfilteret (32), renset filtermedium blir etterfølgende ført tilbake inn i underkammeret (34) av det roterende partikkelfilteret (32) plassert utenfor eksosstrømmen, og blir rotert tilbake inn i eksosgasstrømmen.
2. Fremgangsmåte ifølge krav 2, karakterisert ved at et granulat fortrinnsvis blir brukt som filtermediet rundt hvilket eksosgassen strømmer.
3. Fremgangsmåte ifølge et av kravene 1 til 2, karakterisert ved at oppstrøms av det roterende partikkelfilteret (12, 32), blir SO2oksidert til SO3i en oksidasjonskatalysator (22) der SO3og/eller utfelt H2SO4fungerer til å oksidere sot i roterende partikkelfilter (12, 32) ved delen eller seksjonen av filtermediet rotert inn i eksosgasstrømmen, og der i det minste vanadium i en andel av mer enn 5%, fortrinnsvis mer enn 7%, spesielt foretrukket mer enn 9%, og fortrinnsvis i tillegg kalium og/eller natrium og/eller jern og/eller cerium og/eller cesium og/eller oksider av disse elementene blir brukt som aktive komponenter for oksidasjonen av SO2til SO3, der titanoksid og/eller silisiumoksid, fortrinnsvis stabilisert av wolframoksid, blir brukt som basismaterialet i oksidasjonskatalysatoren.
4. Fremgangsmåte ifølge krav 3, karakterisert ved at nedstrøms oksidasjonskatalysatoren (22), blir et masseforhold mellom SO3og sot justert på minst 7:1, fortrinnsvis minst 12:1, spesielt foretrukket 16:1 i området for det roterende partikkelfilteret (32).
5. Fremgangsmåte ifølge krav 3 eller 4, karakterisert ved at oppstrøms det roterende partikkelfilteret (12, 32), blir NO oksidert til NO2i en oksidasjonskatalysator (40), der NO2fungerer til å oksidere sot i det roterende partikkelfilteret (12, 32) ved delen eller seksjonen av filtermediet rotert inni eksosgasstrømmen, og der oksidasjonskatalysatoren (40) for å oksidere NO til NO2er forbundet i parallell med oksidasjonskatalysatoren (22) for å oksidete SO2til SO3, der begge oksidasjonskatalysatorene (22, 40) kan være adskilt fra eksosgasstrømmen via stoppventiler (41).
