Raws li qhov kub thiab txias sib txawv uas tso cai rau SCR ua haujlwm, feem ntau nws muab faib ua cov catalysts SCR qis-kub (kwv yees li 150 ℃ -260 ℃), feem ntau siv cov tooj liab raws li molecular sieve SCR catalysts; Nruab nrab kub SCR catalyst (kwv yees li 260 ℃ -400 ℃), feem ntau siv vanadium raws li SCR catalyst; Thiab kub SCR catalysts (saum toj no 300 ℃ -600 ℃), feem ntau siv hlau-raws li molecular sieve SCR catalysts.
1. Zoo
Piv rau cov tshuaj catalysts ib txwm muaj, qhov ua tau zoo ntawm denitrification nce ntxiv 10-20% nyob rau hauv tib qho xwm txheej
2. tsis muaj tshuaj lom
Cov tshuaj catalysts hlau ua los ntawm ntau theem oxide tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj.
3. Siv nyiaj tsim nyog
Cov khoom tseem ceeb ntawm cov khoom pov tseg titanium dioxide yog hlau, uas tuaj yeem siv ua cov khoom siv raw los npaj los ntawm kev tswj qhov kub thiab txias ntawm cov khoom tsim tawm thiab lwm yam mob.
4. Cov ntawv thov sib txawv
Cov duab tshwj xeeb ntawm cov catalyst tuaj yeem ua tau raws li cov xwm txheej tshwj xeeb ntawm qhov chaw denitrification
5. Hloov kho rau ntau qhov kub thiab txias
Cov nyhuv denitrification tuaj yeem ua tiav ntawm cov roj flue kub ntawm 200 txog 550 degrees Celsius, haum rau qhov kub thiab txias li ntawm 350 degrees Celsius.
