Ukuza kuthi ga ngoku, kukho iintlobo ezininziumhlaba onqabileyoIi-catalysts zokuhlanjululwa eziye zaphuhliswa kwaye zasetyenziswa, kunye neendlela zabo zokuhlela nazo zahluka.Ulwahlulo olulula kwaye olunembile lusekelwe kwimilo ye-catalyst, enokuthi ihlulwe ibe yintlobo ezimbini: i-granular kunye ne-honeycomb.I-granular catalysts isetyenziswa ngokuqhelekileyo γ- i-Al2O3 ngumthwali onomthamo omkhulu womthwalo, onokulayisha i-10% ukuya kwi-20%umhlaba onqabileyokunye nezinye isiseko sentsimbi oxides.Inokumelana neempembelelo ezintle, kodwa ukuxhathisa kwayo kuphezulu, okuchaphazela amandla kunye noqoqosho.I-honeycomb shaped catalysts ngokuqhelekileyo zisebenzisa i-Dongqingshi, i-mullite, i-spodumene, kunye ne-alloys zetsimbi njengabathwali, kunye nomthamo omncinci wokulayisha kwaye ulungele ukulayisha isinyithi esixabisekileyo.I-honeycomb carrier inomthamo omncinci wokushisa, ukusebenza kakuhle kokufudumala, ukusebenza kwamandla, kunye nokusebenza kakuhle kwezoqoqosho, kwaye ngoku isetyenziswa ngokubanzi njengomphathi.Nangona indlela yokwahlula ngokusekelwe kwimilo ye-catalysts ilula, ukubunjwa kwee-catalysts, ngokukodwa amacandelo asebenzayo, akukwazi ukuchazwa ngokucacileyo.
Ukuba amaqela omsebenzi we-catalysts ahlukile,umhlaba onqabileyoIi-catalysts zinokwahlulwa zibe ziindidi ezimbini:umhlaba onqabileyoisiseko sesinyithi se-oxide catalysts kunye nesiseko somhlaba esinqabileyo se-metal oxide catalysts ezinezixa-mali zomkhondo we-catalysts zentsimbi exabisekileyo.Olokuqala luhlobo lwe-catalyst oluqhelekileyo olusetyenziswa ngoku, olunesiphumo esihle sokuhlanjululwa kwi-CO kunye ne-HC, kodwa isiphumo esincinci sokuhlanjululwa kwi-NOx.Le yokugqibela inesiphumo esihle sokuhlanjululwa kwi-NOx, ngoko iya kuba yikhokelo yophuhliso oluphambili lwe-catalysts yokucoca igesi e-China.
