What are the Key Reactions in a Catalytic Converter?
The primary reactions occurring in a catalytic converter include:
Oxidation of Carbon Monoxide: CO is converted into carbon dioxide (CO2) through the reaction CO + 1/2 O2 → CO2. Reduction of Nitrogen Oxides: NOx compounds are reduced to nitrogen (N2) and oxygen (O2) through the reaction 2NO → N2 + O2. Oxidation of Hydrocarbons: Unburnt hydrocarbons are converted to carbon dioxide and water (H2O) through reactions like CmHn + (m+n/4)O2 → mCO2 + n/2H2O.
