SCR catalyst is mainly used to reduce NOx in diesel engine exhaust with Urea-SCR technology. Diesel SCR catalyst is mainly divided into Vanadium based SCR (V-SCR) catalyst and Molecular sieve based SCR catalyst.
SCR Catalyst Depending on the NO/NO2 content in the exhaust gas, two important main SCR reactions are distinguished:
Without NO2: Standard SCR: 4 NH3+ 4 NO + O2 → 4 N2 + 6 H2O
With NO2: Fast SCR: 4 NH3+ 2 NO + 2 NO2 → 4 N2 + 6 H2O
Advantages:Low pressure dropHigh surface areaGood consistency water absorptionLow thermal expansion coefficientGood heat shock resistance and heat vibration resistanceIdeal matching with various active catalyst components
Features Our company has developed SCR catalysts for meeting NOx emission control both of mobile and stationary applications. Depending on different application scene, we can provide matched wash-coated products including Fe/zeolite (450~620 oC), Cu/Zeolite (190~550 oC), vanadium-based metal oxides (230~470 oC) and Mn-containing oxide catalysts (130~250 oC).
