Pt Pd Rh Universal Catalyst Euro 4 5 6 Metallic Catalyst Substrates

​Universal Catalyst Euro 4/5/6 Honeycomb Ceramic/Metal for Auto Exhaust Purification

Universal Catalyst Euro 4/5/6

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.

WFEC professionally produces various kinds of automobile and non-road catalysts, with metal or ceramic honeycomb as the carrier, coated with high surface area and good thermal stability washcoat with precious metals such as platinum, palladium and rhodium. When the exhaust gas flows through the catalyst, harmful hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NO_X) form the internal combustion engine, converted into harmless CO₂, H₂O and N₂, so as to achieve the purpose of purification. The catalyst products can meet the emission standard of Euro 3, Euro 4, Euro 5, Euro 6, EPA and CARB.

Technical Advantages:

1. Good low tempreture light off performance (T50 ≤ 180 ℃ ).

2. Higher conversion rate (CO,THC,SOF ≥ 97%).

3. Precious metals & rare earth compound catalyst technology provides the high oxygen storage and high stability catalyst.

4. Precise control of precious metals and other materials during catalyst manufacturing process.

5. Vehicle complete system matching technology and systematic solutions for the customer.

6. Up to Euro VI Emission Standard.
