Ngokwezinga lokushisa elihlukile elivunyelwe ukusebenza kwe-SCR, ngokuvamile ihlukaniswe ngama-catalyst e-SCR anokushisa okuphansi (cishe u-150 ℃ -260 ℃), ikakhulukazi kusetshenziswa ama-catalyst e-SCR esisefo sama-molecule asekelwe ethusi; i-catalyst ye-SCR enokushisa okuphakathi (cishe u-260 ℃ -400 ℃), ikakhulukazi kusetshenziswa i-catalyst ye-SCR esekelwe ku-vanadium; kanye nama-catalyst e-SCR anokushisa okuphezulu (ngaphezu kuka-300 ℃ -600 ℃), ikakhulukazi kusetshenziswa ama-catalyst e-SCR esisefo sama-molecule asekelwe ensimbi.
1. Kusebenza kahle
Uma kuqhathaniswa nama-catalyst endabuko, ukusebenza kahle kwe-denitrification kukhushulwa ngo-10-20% ngaphansi kwezimo ezifanayo.
2. okungeyona into enobuthi
Ama-catalyst e-oxide enziwe nge-iron asekelwe ezigabeni eziningi awayona into enobuthi futhi awayona ingozi emvelweni.
3. Isebenza kahle
Ingxenye eyinhloko yemfucuza yokukhiqiza i-titanium dioxide yinsimbi, engasetshenziswa njengezinto zokusetshenziswa ukulungisa ngokulawula izinga lokushisa lokukhiqiza nezinye izimo.
4. Amafomu ezicelo ahlukahlukene
Izimo ezithile ze-catalyst zingenziwa ngokuya ngezimo ezithile zendawo yokuhlanza amanzi
5. Zivumelanise nobubanzi obubanzi bamazinga okushisa
Umphumela wokuhlanza ungatholakala emazingeni okushisa egesi yomoya ophumayo asukela ku-200 kuya ku-550 degrees Celsius, afanele amazinga okushisa azungeze ama-350 degrees Celsius.

Inqubo yokususa i-nitrification yokukhetha (i-SCR) esebenzisa ama-catalyst e-nitrogen oxide isetshenziswe kabanzi emikhakheni yezimboni njengezitshalo zamandla ezishisayo, izitshalo zamandla ezisebenzisa amalahle, amayunithi e-turbine yegesi, ukushiswa kwemfucuza, insimbi, amakhemikhali kaphethroli, kanye namayunithi enjini yokushisa yangaphakathi.
