Ngokwemigangatho eyahlukeneyo yobushushu evunyelweyo yokusebenza kwe-SCR, ngokubanzi yahlulwe yaba zii-catalysts ze-SCR ezikumgangatho ophantsi (malunga ne-150 ℃ -260 ℃), ikakhulu kusetyenziswa ii-catalysts ze-SCR ezisekelwe kubhedu; i-catalyst ye-SCR yobushushu obuphakathi (malunga ne-260 ℃ -400 ℃), ikakhulu kusetyenziswa i-catalyst ye-SCR esekwe kwi-vanadium; kunye nee-catalysts ze-SCR ezikumgangatho ophezulu (ngaphezulu kwe-300 ℃ -600 ℃), ikakhulu kusetyenziswa ii-catalysts ze-SCR ezisekelwe ku-iron-based molecular sieve.
1. Isebenza kakuhle
Xa kuthelekiswa nee-catalysts zemveli, ukusebenza kakuhle kwe-denitrification kunyuswa nge-10-20% phantsi kweemeko ezifanayo.
2.engenabungozi
Ii-catalysts ze-oxide ezisekelwe kwi-iron ezisebenzisa i-multiphase azinabungozi kwaphela kwaye azinabungozi kwindalo esingqongileyo.
3. Ixabiso elifanelekileyo
Eyona nto iphambili kwinkunkuma yokuvelisa i-titanium dioxide yintsimbi, engasetyenziswa njengezinto eziluhlaza ukulungiselela ngokulawula ubushushu bemveliso kunye nezinye iimeko.
4. Iifomu zesicelo ezahlukeneyo
Iimilo ezithile ze-catalyst zingenziwa ngokweemeko ezithile zendawo yokuchithwa kwe-nitrogen
5. Ziqhelanise nohlobo olubanzi lwamaqondo obushushu
Isiphumo sokuchithwa kwe-denitrification sinokufezekiswa kumaqondo obushushu egesi yolwelo aqala kuma-200 ukuya kuma-550 degrees Celsius, afanelekileyo kumaqondo obushushu amalunga nama-350 degrees Celsius.

Inkqubo yokunciphisa i-selective reduction (SCR) kusetyenziswa ii-catalysts ze-nitrogen oxide isetyenziswa kakhulu kwiindawo zoshishino ezifana nezityalo zamandla obushushu, izityalo zamandla ezisebenzisa amalahle, iiyunithi ze-gas turbine, ukutshisa inkunkuma, intsimbi, iikhemikhali zepetroli, kunye neeyunithi zeenjini zokutsha ngaphakathi.
