Kusvika ikozvino, kune marudzi akawanda erare pasiekuchenesa catalysts akagadziridzwa uye akashandiswa, uye maitiro avo emhando dzakasiyana. Kurongeka kwakapfava uye kwakajeka kunobva pachimiro cheiyo catalyst, iyo inogona kukamurwa kuva mhando mbiri: granular uye uchi. Granular catalysts inowanzo shandiswa γ- Al2O3 inotakura ine hombe yekuremerwa, inogona kurodha 10% kusvika 20%rare pasiuye mamwe mabhesi esimbi okisijeni. Iine maitiro akanaka ekupikisa, asi kumira kwayo kwemhepo kwakakwirira, iyo inokanganisa simba rayo uye hupfumi. Zvigadzirwa zvehuchi zvehuchi zvinowanzoshandisa Dongqingshi, mullite, spodumene, uye alloys esimbi sevatakuri, vane diki yekurodha uye yakakodzera kurodha simbi dzinokosha. Mutakuri wemizinga ine huchi hudiki hwekupisa, kuita kwakanaka kwekudziya-up, kuita kwesimba, uye kugona kwehupfumi, uye parizvino inoshandiswa zvakanyanya sekutakura. Kunyange zvazvo nzira yekuronga inobva pachimiro chezvigadziriswe chiri nyore, kuumbwa kwezvinokonzera, kunyanya zvikamu zvinoshanda, hazvigoni kutaurwa zvakajeka.
Kana mapoka ezviitwa ezvinokonzeresa akasiyana,rare pasicatalysts inogona kukamurwa kuva marudzi maviri:rare pasibase metal oxide catalysts uye isingawanzo pasi base simbi oxide catalysts ine inoteedzera huwandu hweakakosha simbi inokonzeresa. Iyo yekutanga imhando yecatalyst inowanzoshandiswa pari zvino, ine yakanaka yekunatsa mhedzisiro paCO neHC, asi zvishoma kushomeka kwekuchenesa maitiro paNOx. Iyo yekupedzisira ine yakanaka yekuchenesa mhedzisiro paNOx, saka ichave iyo huru yekusimudzira kutungamira kwemuswe gasi rekuchenesa catalysts muChina.
