Denitration | what types of catalysts are used in SCR denitration system?
Selective catalytic reduction method is to control the exhaust NOx of diesel engine, and use No3 or urea as reducing substance to reduce No3 to N2 and H2O under the action of a certain temperature and
|SCR catalyst||Low temperature catalyst||Medium temperature catalyst||High temperature catalyst|
