TWC Three Way Catalyst

Three-way catalysts (TWC) are designed to simultaneously convert three pollutants to harmless emissions:

• Carbon Monoxide (CO) → Carbon Dioxide (CO2)
• Hydrocarbons (HC) → Water (H2O)
• Oxides of Nitrogen (NOx) → Nitrogen (N2)

A three-way catalyst can cut CO, HC and NOx by over 99% if the air to fuel ratio is accurately controlled. Three-way catalysts will only give full conversion of each of these three pollutants in a gas stream containing a stoichiometric ratio of CO and NOx.

Product Highlights:

1.Good thermal properties: small thermal expansion coefficient (TEC), highly resistant to thermal shock.
2.Good coating properties: good water absorption with small fluctuation, strong sorption for catalysts, high surface area.
3.Good warming-up properties: low material density, rapid light-off, low pressure drop, high conversion rate.
4.High surface area, high CPSI, thin wall, low back pressure, high compressive strength.

Product Applications:

• Passenger cars (PCs)
• Passenger trucks (PTs)
• Hybrid electric vehicles (HEVs)

Product advantages:

With nearly 20 years of technology accumulation, we can provide customers with rich customized solutions. TWCs can meet Euro-VI and China-VI regulations, especially for RDE. TWC has been mass produced and successfully applied on more than 100 different domestic and foreign automotive projects meeting China-VI emission standard.
