Web1 day ago · Catalytic Reactors. Catalytic reactors, also referred to as selective catalytic reduction (SCR) systems, are air pollution control devices widely used to mitigate nitrogen oxide (NO x) emissions produced by the burning of fossil fuels in industrial applications. These devices first inject ammonia into the industrial exhaust and emissions, which ... WebA three-way catalytic converter has three simultaneous tasks: Reduction of nitrogen oxides to nitrogen and oxygen: 2NOx → xO2 + N2. Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2. Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + [ (3x+1)/2]O2 → xCO2 + (x+1)H2O. WebIn the presence of oxygen, the three-way catalyst becomes ineffective in reducing NOx. While stoichiometric operation of diesel engines has been investigated to determine their suitability for three-way catalyst technology, the challenges to operating diesel with a stoichiometric air-to-fuel ratio are costly to overcome [3369][3371][3370].
