Sida ku cad heerarka kala duwan ee heerkulka loo oggol yahay hawlgalka SCR, guud ahaan waxaa loo qaybiyaa kataliyayaal SCR heerkul hooseeya (qiyaastii 150 ℃ -260 ℃), inta badan waxaa la isticmaalaa kataliyayaal SCR shaandho molecular ah oo ku salaysan naxaas; Kataliyayaal SCR heerkul dhexdhexaad ah (qiyaastii 260 ℃ -400 ℃), inta badan waxaa la isticmaalaa kataliyayaal SCR oo ku salaysan vanadium; Iyo kataliyayaal SCR heerkul sare leh (ka sarreeya 300 ℃ -600 ℃), inta badan waxaa la isticmaalaa kataliyayaal SCR shaandho molecular ah oo ku salaysan birta.
1. Waxtar leh
Marka la barbardhigo kiciyeyaasha dhaqameed, waxtarka denitrification-ka ayaa kordhay 10-20% xaaladaha isku midka ah
2.aan sun ahayn
Kataliyayaasha oksaydhka ee ku salaysan birta ee wejiyada badan leh gebi ahaanba ma aha kuwo sun ah oo aan waxyeello u lahayn deegaanka.
3. Kharash-ool ah
Qaybta ugu weyn ee qashinka wax soo saarka titanium dioxide waa birta, taas oo loo isticmaali karo sidii walxo cayriin ah si loogu diyaariyo iyadoo la xakameynayo heerkulka wax soo saarka iyo xaaladaha kale.
4. Foomamka codsiyada kala duwan
Qaabab gaar ah oo kiciya ayaa la samayn karaa iyadoo la raacayo xaaladaha gaarka ah ee goobta denitrification
5. La qabso heerkul kala duwan
Saamaynta ka saarista wasakhda waxaa lagu gaari karaa heerkulka gaaska qiiqa oo u dhexeeya 200 ilaa 550 darajo Celsius, oo ku habboon heerkulka qiyaastii 350 darajo Celsius.

Habka loo yaqaan 'denitrification' ee loo yaqaan 'selective detentrification' (SCR) oo adeegsanaya kaaliyayaasha nitrogen oxide ayaa si weyn loogu isticmaalay goobaha warshadaha sida warshadaha korontada ku shaqeeya, warshadaha korontada ku shaqeeya dhuxusha, cutubyada gaaska, gubista qashinka, birta, kiimikooyinka batroolka, iyo cutubyada matoorada gubashada gudaha.
