I le taimi nei, e tele ituaiga oeleele seaseafa'amamāina fa'amamafa na fa'atupuina ma fa'aogaina, ma o latou fa'avasegaga e eseese fo'i.O se faʻavasegaga faigofie ma faʻaogaina e faʻavae i luga o foliga o le catalyst, lea e mafai ona vaevaeina i ni ituaiga se lua: granular ma honeycomb.E masani ona faʻaaogaina faʻamaʻi faʻapitoa γ- Al2O3 o se ave faʻatau ma le tele o le uta gafatia, lea e mafai ona utaina le 10% i le 20%eleele seaseama isi oxide u'amea faavae.E lelei le tete'e o a'afiaga, ae o lona fa'asao e maualuga, e a'afia ai lona malosi ma lona tamaoaiga.E masani ona faʻaogaina e faʻapipiʻi faʻapipiʻi faʻapipiʻi le Dongqingshi, mullite, spodumene, ma uʻamea uʻamea e fai ma ave, faʻatasi ai ma se laʻititi laʻititi ma talafeagai mo le utaina o metala taua.O le faʻapipiʻi meli o loʻo i ai se laʻititi laʻititi o le vevela, lelei faʻamafanafanaga, faʻaogaina o le eletise, ma le faʻaleleia o le tamaoaiga, ma o loʻo faʻaaogaina lautele i le taimi nei o se vaʻa.E ui lava o le faʻavasegaina o auala e faʻavae i luga o foliga o catalysts e faigofie, o le tuufaatasiga o catalysts, aemaise lava vaega galue, e le mafai ona faʻaalia manino.
Afai e ese le vaega o gaoioiga o catalysts,eleele seaseae mafai ona vaevaeina catalysts i ni ituaiga se lua:eleele seaseau'amea u'amea fa'avae fa'ato'aga ma fa'ato'aga fa'ameamea fa'avae u'amea fa'avae fa'atasi ma fa'asologa o aofa'i o fa'aupuga u'amea taua.O le mea muamua o se ituaiga o faʻamalosi e masani ona faʻaaogaina i le taimi nei, lea e iai sona aafiaga lelei ile faʻamamaina ile CO ma le HC, ae e le lelei le faʻamamaina ole aafiaga ile NOx.O le vaega mulimuli o loʻo i ai se aafiaga faʻamamaina lelei i luga ole NOx, o lea o le a avea ma taʻiala autu o le atinaʻeina o faʻamaʻi faʻamaʻaina o le siʻusiʻu i Saina.
