Umicore Catalysis is one of the leading suppliers of SCR catalyst solutions for Gas Turbines, Biomass, FCC Units and Crackers. Umicore’s air pollution technology includes a series of unique catalysts for the control of nitrogen oxides (NOx), the reduction of carbon monoxide (CO) and volatile organic compounds (VOC) from stationary or mobile sources.
| 1.NOx removal by the SCR DeNOx process |
 |
NH3 is injected into the flue gas via an Ammonia Injection Grid (AIG) as a reducing agent
• The NH3 must be distributed thoroughly into the gas stream prior to the catalyst
• The mixed gas then passes through the catalyst where
the NH3 reacts with NOx to form N2 and H2O vapor |
 |
| 2.Product range |
• Channel size: 2.7 – 9 mm
• Wall thickness: 0.3, 0.4, 0.6, 0.8 and 1.0 mm
