SCR Catalyst (NOx Control Catalyst)

The Fast SCR reaction is important for effective NO_x control, especially at lower exhaust gas temperatures around the Urea dosing threshold. In order to increase the NO₂ content in the exhaust gas, either a DOC or a cDPF can be used upstream of the SCR catalyst.

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)

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
