SCR NOx Control Catalyst for Diesel Engine Fe/zeolite Cu/Zeolite Vanadium

SCR Catalyst (NOx Control Catalyst)

Selective catalytic reduction (SCR) systems work by chemically reducing NOx (NO and NO₂) to nitrogen (N₂). WFEC can offer coated and extruded catalysts. In a lean gas stream, it is necessary to add a reductant such as ammonia to the system to enable this reaction. Ammonia-SCR systems react ammonia (NH₃) with the NOx to form nitrogen (N₂) and water (H₂O). There are three reaction pathways:

4NH₃ + 4NO + O₂ → 4N₂ + 6H₂O
2NH₃ + NO + NO₂ → 2N₂ + 3H₂O
8NH₃ + 6NO₂ → 7N₂ + 12H₂O

Any source of ammonia can be used but most commonly the source is an aqueous solution of urea. This decomposes in the exhaust stream in two stages to form ammonia and carbon dioxide (CO₂):

NH₂C(O)NH₂ → HNCO + NH₃

↓

HNCO + H₂O → CO₂ + NH₃

Advantages:

Low pressure drop
High surface area
Good consistency water absorption
Low thermal expansion coefficient
Good heat shock resistance and heat vibration resistance
Ideal matching with various active catalyst components

Features

WFEC has developed SCR catalysts for meeting NOx emission control both of mobile and stationary applications. Depending on different application scene, WFEC 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).

Applications

Boilers / Turbines

Diesel engine emissions

Engine systems for vessels

Industrial processes

Others (iron and steel making, coking plant and cement manufacturing)
