SCR DeNOx catalysts as coated or solid extrudate
Selective catalytic reduction systems (SCR or DeNOx) function by the chemical reduction of NOx (NO and NO2) to nitrogen (N2) using ammonia. We offer coated
DeNOx exhaust gas purification is used to remove nitrogen oxides from engine exhaust. Why are nitrogen oxides produced? Because in the “explosion” when the fuel-air mixture ignites, the air is heated to over 1,000 °C, and N₂ reacts with O₂ to form NOx. These nitrogen oxides in exhaust gases are toxic and cause forest dieback. Stationary engines are huge and mostly used for power generation; in gas engines, NOx generation is low, and here, DeNOx exhaust gas purification primarily reduces CO and formaldehyde using total oxidation catalysts.
