Iyo catalytic inoshandura ndiyo inonyanya kukosha yekunze yekunatsa mudziyo yakaiswa mu exhaust system, iyo inogona kushandura magasi anokuvadza akadai CO, HC uye NOx kubva mumhepo yekuburitsa kuita isingakuvadzi kabhoni dhisiki, mvura uye nitrogen kuburikidza neoxidation uye kuderedza.

Iyo nzira nhatu-catalyst (TWC) yemudhudhudhu kusangana neEPA, CARB uye Euro III, IV, V, VI emission standard.Nekushandisa iron chromium aruminiyamu alloy (FeCrAl) huchi muviri semutakuri, platinamu (Pt), palladium (Pd), rhodium (Rh) uye mamwe masimbi akakosha seanokonzeresa anoshanda zvikamu.Kushandiswa kwehunyanzvi hwekuputira tekinoroji kuvandudza kunamatira kwesimbi dzakakosha pane esimbi substrate, kutendeuka kushanda zvakanaka kweCO, HC uye NOX kunogona kusvika pamusoro pe85%, izvo zvichabatsira macatalysts kusangana 30000 Km durability chinodiwa.

Usati wapinda muVOCs gasi, zvinodikanwa kuti upinde mumhepo inoyerera kuti unyatsopisa catalyst (preheat kusvika 240ºC ~ 350ºC) Catalyst inofanira kubatwa zvinyoro, uye kutungamira kwegomba rinokonzera kunofanira kuenderana negwaro rekuyerera kwemhepo. paunenge uchizadza, uye wakaiswa pedyo, pasina mapeji.The optimal operating tembiricha ye catalyst is 250 ~ 500ºC, iyo inopedza gasi yemagetsi ndeye 500 ~ 4000mg / m3, uye GHSV ndeye 10000 ~ 20000h-1.Inofanira kudziviswa zvakanyanya sezvinobvira kudzivirira kuwedzera kamwe kamwe kwemhepo inopisa gasi kana kutonhora kwenguva refu kwechigadzirisiro pamusoro pe 600ºC. Iyo inogadzirisa inofanira kunge isina unyoro, usanyura kana kushambidza nemvura.

Kuburikidza necatalytic oxidation yemarudzi ese emaindasitiri anoshata marara gasi maVOCs, kuzadzisa zviyero zvemaindasitiri, zvinonyanya kushandiswa mukupisa kupisa kwechikafu, makemikari, kudhinda, michina, kugadzira mota, petrochemical, organic makemikari, mishonga yemakemikari indasitiri inoburitsa ine carbon monoxide. , mahydrocarboni anonhuwirira, mahydrocarbon uye zvinobva mukati meokisijeni, nezvimwewo zvine muchetura uye zvinokuvadza gasi remarara.
