EMPRO™ TWC Three-way Catalysts

BASF's TWC (Three-Way Conversion) catalyst technology feature a patented construction of Precious Metals (e.g. Platinum, Palladium, Rhodium) that enables it to significantly outperform conventional three-way conversion catalysts in the oxidation of hydrocarbons (HC) and carbon monoxide (CO).

This state-of-the-art platform technology uses BASF's patented, segregated washcoat technology, which precisely places the precious metals within the washcoat, resulting in several important benefits:

  • Optimal use of precious metals
  • Lower cost and higher effectiveness
  • Higher conversions of CO, HC and nitrogen oxides (NOx) over a wide range of conditions

BASF's TWC catalysts:

  • Have a lower light-off temperature
  • Offer high temperature stability enabling the catalyst to be moved closer to the manifold
  • Minimize hydrogen sulfide (H2S) emissions without using nickel
  • Have outstanding resistance to lead
  • Have a stable oxygen storage function to help original equipment manufacturers (OEMs) meet On-Board Diagnostics II (OBDII) requirements

EMPRO™ FWC™ Four-Way Catalysts

The innovative single component FWC™ (Four-Way Conversion) catalyst can remove Particulate Matter (PM), as well as CO (Carbon Monoxide), HC (Hydrocarbons) and NOx (Nitrogen Oxides) from gasoline-engine exhaust.   Upcoming Euro 6 and US Tier 3 regulations will enforce, besides the well-known limits for HC, CO and NOx, tighter control of PM emissions from gasoline-engine powered vehicles. BASF has developed innovative FWC™ catalyst technologies that can be applied in a system, together with a standard TWC, as a CC (Close Couple) or UF (Under-Floor) or even as a FWC-only device for a fully integrated system. The innovative FWC™ catalyst combines the functionality of a TWC catalyst with a filter to remove all four pollutants with just one component. The benefits include:

  • Smart solutions to lower backpressure impact
  • Potential to save space
  • Ensure particulate emission below tight regulation limits

EMPRO™ LGC Lean GDI Catalysts

The patented BASF Lean GDI (Gasoline Direct Injection) Catalyst technology provides the additional NOx (nitrogen oxides) removal required from the exhaust of GDI engines. These engines use lean combustion (excess of air) to deliver improved fuel economy. However NOx exhaust emissions can increase and are a challenge to remove under these lean operating conditions. The Lean GDI catalyst is designed to operate under lean conditions and can be placed after the TWC catalyst to provide additional NOx conversion.                           

Benefits include:

  • Exceptionally high thermal stability
  • High NOx removal activity at high temperature
  • High NOx storage capacity
  • High NOx reduction efficiency
