Particulate oxidation catalyst (POC) yog ib qho khoom siv uas tuaj yeem ntes thiab khaws cov ntaub ntawv carbonaceous PM rau lub sijhawm txaus los ua kom oxidation.Nyob rau tib lub sijhawm, nws muaj qhov qhib ntws channel tso cai rau cov pa ntws tawm txawm tias PM tuav lub peev xwm saturated.Nyob rau hauv lwm yam lus, feem ntau oxidation catalyst yog ib tug tshwj xeeb diesel oxidation catalyst, uas muaj peev xwm ua kom haum cov khoom soot hais.Nyob rau hauv tus txheej txheem hu ua regeneration, cov khoom ntes yuav tsum tau muab tshem tawm los ntawm cov cuab yeej los ntawm oxidation rau cov khoom gaseous.POC regeneration feem ntau yog ua tiav los ntawm cov tshuaj tiv thaiv ntawm soot thiab nitrogen dioxide tsim nyob rau hauv NO2.Tsis zoo li cov lim dej diesel (DPF), POC tsis thaiv thaum cov hmoov av puv rau nws lub peev xwm siab tshaj plaws yam tsis muaj kev tsim dua tshiab.Ntawm qhov tsis sib xws, PM conversion efficiency yuav maj mam txo, kom PM emissions tuaj yeem dhau los ntawm cov qauv.
Particulate oxidation catalyst, ib qho tshiab PM emission tswj thev naus laus zis, muaj ntau dua particle tswj kev ua haujlwm zoo dua li doc, tab sis qis dua li cov lim dej hauv diesel.
Particle oxidation catalysts (POC) yog cov cuab yeej uas tuaj yeem ntes thiab khaws cov khoom siv PM carbonaceous rau lub sijhawm txaus rau nws cov catalytic oxidation, thaum muaj qhov qhib ntws-los ntawm cov kab uas tso cai rau cov pa tso pa tawm, txawm tias PM tuav lub peev xwm saturated.
Piculate oxidation catalyst (POC)
- Thawj lub hom phiaj: nce particle deposition
Tsis muaj qhov tseem ceeb hauv kev rov qab siab hauv cov catalyst thiab kev pheej hmoo ntawm kev thaiv yog zam
