The three-way catalyst is used in rich-burn or stoichiometric engines for simultaneous conversion of oxides of nitrogen (NOx), carbon monoxide (CO), hydrocarbons (HC), formaldehyde (CH2O) and EPA classified Hazardous Air Pollutants (HAPs). The three-way catalyst is effective in a wide variety of engine applications and fuels, including natural gas, propane and gasoline. A closed loop air-fuel ratio controller is required for the three-way catalyst to work effectively.
Typical Conversion Efficiencies
Power generation and co-generation applications require highly durable catalysts capable of operating over 8000 hours per year without the need for significant maintenance. Design features for easy access and maintenance of the catalyst elements are of critical importance. DCL offers a variety of oxidation and three-way catalyst products designed for the tough specifications of power generation equipment packagers and operators.
