Zvichienderana nemazinga akasiyana ekupisa anobvumirwa kushanda kweSCR, inowanzo kamurwa kuita macatalysts eSCR anodziya tembiricha yakaderera (anenge 150 ℃ -260 ℃), kunyanya uchishandisa macatalysts eSCR anodziya tembiricha yemhangura; macatalysts eSCR anodziya tembiricha yepakati (anenge 260 ℃ -400 ℃), kunyanya uchishandisa vanadium based SCR catalysts; uye macatalysts eSCR anodziya tembiricha yepamusoro (anopfuura 300 ℃ -600 ℃), kunyanya uchishandisa macatalysts eSCR anodziya tembiricha yesimbi.
1. Inoshanda zvakanaka
Zvichienzaniswa nezvinoshandiswa pakugadzira zvinhu zvechinyakare, kushanda kwe denitrification kunowedzerwa ne10-20% pasi pemamiriro akafanana.
2.isina chepfu
Zvinokonzera simbi zvine huwandu hwakawanda hwe oxide hazvina chepfu zvachose uye hazvikuvadzi nharaunda.
3. Inodhura-inoshanda
Chinhu chikuru chinoumba marara ekugadzira titanium dioxide isimbi, iyo inogona kushandiswa sezvinhu zvekugadzira nekudzora tembiricha yekugadzira nezvimwe zvinhu.
4. Mafomu akasiyana-siyana ekunyorera
Maumbirwo chaiwo e catalyst anogona kugadzirwa zvichienderana nemamiriro chaiwo enzvimbo ye denitrification
5. Chinja zvichienderana nekupisa kwakasiyana-siyana
Kuchenesa kwemafuta kunogona kuwanikwa pakupisa kwemhepo inoyerera kubva pa200 kusvika ku550 degrees Celsius, yakakodzera tembiricha inosvika 350 degrees Celsius.
