The three-way catalytic converter can eliminate 90% amount of the three main pollutants ( HC, CO and NOx). It is suitable for manifold, close-coupled or under-chassis applications.
How does catalytic converter work
In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe. The catalyst helps to convert carbon monoxide into carbon dioxide(CO to CO2 ). It converts the hydrocarbons into carbon dioxide(CO2 ) and water. It also converts the nitrogen oxides back into nitrogen and oxygen.
Substrate: Ceramic honeycomb substrate or metal honeycomb substrate.
Catalytic Supporter:Rare-earth oxygen-storage material.
Catalytic Promoter: CeO2, ZrO2, La2O3 and so on.
Active Components: Pt, Pd, Rh and so on.
Shell Material: 409 or 304 stainless steel.
Emission standard: Meet Euro 2, 3, 4, 5, EPA and CARB.
Working Principle:
1. Oxidation of carbon monoxide (CO) to carbon dioxide
2CO+ O2 → 2CO2
2. Oxidation of un-burnt hydrocarbons (HC) to carbon dioxide and water
2CxHy + (2x+y/2)O2 → 2xCO2 + yH2O
3. Reduction of nitrogen oxides (NOx) to nitrogen and oxygen
2NOx → xO2 + N2
