When you switch on your car's engine, exhaust gases flow through the Catalytic Converter, where the catalysis process occurs. The reaction starts as the temperatures in the exhaust system rise. Oxides of nitrogen (NOX) are broken down into simple carbon dioxide (CO2) and nitrogen (N2).
Carbon monoxide (CO) and Hydrocarbons (HC) are oxidized to create carbon dioxide (CO2) and water (H2O). Catalyst reaction speed and efficiency are improved by catalysis surface area, gas composition, and operating temperature. Besides, the catalyst begins the reaction at around 300℃, but purification occurs when it reaches temperatures of at least 415℃.
