Kuze kube manje, kunezinhlobo eziningi zeUmhlaba ongavamileAma-catalysts ahlanzeke athuthukisiwe futhi asetshenzisiwe, futhi izindlela zabo zokuhlukanisa ziyehluka. Ukuhlukaniswa okulula futhi okunembile kususelwa esimweni se-catalyst, esingahlukaniswa ngezinhlobo ezimbili: Granular and HonneyComb. Ama-catalysts e-granular asetshenziswa ngokujwayelekileUmhlaba ongavamilenezinye izisekelo zensimbi oxides. Inokumelana nomthelela omuhle, kepha ukumelana kwayo okuqeda amandla kuphezulu, okuthinta amandla alo nomnotho. Ama-catalysts wezinyosi abunjiwe ajwayele ukusebenzisa i-dongqingsing, i-mpullite, iSpodumene, kanye nama-alloys wensimbi njengabathwali, anendawo encane yokulayisha futhi efanelekile ukulayisha izinsimbi eziyigugu. Isithwali sezinyosi sezinyosi sinamandla amancane okushisa, ukusebenza okuhle kokufudumeza okufudumele, ukusebenza kwamandla, kanye nokusebenza kwezomnotho, futhi kusetshenziswa kabanzi njengothwala. Yize indlela yokuhlukaniswa isuselwa esimweni se-catalysts ilula, ukwakheka kwama-catalysts, ikakhulukazi izakhi ezisebenzayo, akunakushiwo ngokusobala.
Uma amaqembu womsebenzi ama-catalysts ahlukile,Umhlaba ongavamileAma-Catalysts angahlukaniswa ngezinhlobo ezimbili:Umhlaba ongavamileI-Base Metal Oxide Catalysts kanye ne-Rare Earth Base Metal Oxide Catalysts ngezinombolo zokulandela zamanani wensimbi ayigugu. Owangaphambili uluhlobo lwe-catalyst esetshenziswa kakhulu njengamanje, olunomphumela omuhle wokuhlanza ku-CO ne-HC, kepha umphumela wokuhlanza ongemuhle kancane ku-nox. Lesi sakamuva sinomphumela omuhle wokuhlanza ku-nox, ngakho-ke kuzoba ukuqondiswa okuphambili kwentuthuko yama-tail gaur hlanza ama-catalysts eChina.
