Catalyst Removal

1.Exhaust Gas Entry:

Exhaust gases from the engine enter the catalytic converter. These gases contain pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx).

2.Reduction Catalyst (First Stage):

The first section of the catalytic converter contains rhodium and sometimes platinum, which help reduce NOx emissions.
Reaction: NOx gases are reduced by removing oxygen atoms, breaking them down into nitrogen (N2) and oxygen (O2).
Equation: 2NOx → xO2 + N2

3.Oxidation Catalyst (Second Stage):

The second section contains platinum and palladium, which help oxidize CO and HC.
Carbon Monoxide Oxidation: CO reacts with O2 to form carbon dioxide (CO2).
Equation: 2CO + O2 → 2CO2
Hydrocarbons Oxidation: HC reacts with O2 to form CO2 and water (H2O).
Equation: CxHy + O2 → CO2 + H2O

4.Exhaust Gas Exit:

The converted, less harmful gases (primarily CO2, N2, and H2O) exit the catalytic converter and are released through the vehicle’s exhaust system.
