Catalysts for Diesel Engines

U.S. and European legislation has required significant reduction in particulate matter (PM) and oxides of nitrogen (NOx) emissions from on-road and off-road diesel vehicles. Catalysts using traditional technology will require high loadings of platinum group metals to comply with these standards, and diesel engine manufacturers are very concerned about the high price of these units.

What are Catalysts for Diesel Engines?

Diesel engines are more durable and are more fuel efficient than gasoline engines but can pollute significantly more. Current techniques for diesel engines to meet emissions standards require the use of several methods, including diesel oxidation catalysts, catalyzed diesel particulate filters and selective catalytic reduction systems.

We have been producing diesel oxidation catalysts since 2000. In addition, we are working with leading heavy duty diesel engine and substrate manufacturers to develop diesel oxidation catalysts, catalyzed diesel particulate filters and selective catalytic reduction systems utilizing our catalyst technology. This is in order to meet United States and European light and heavy duty regulations with minimal or no platinum group metals.

Do you have cost concerns as a diesel engine manufacturer?

Our zero and low platinum group metals catalysts are able to effectively address diesel engine manufacturers' cost concerns. Additionally, fleet owners and operators complying with existing on-road legislation and regulations will be looking for more cost-effective suppliers for existing retrofit technology applications as well as potential expansion into urea-based selective catalytic reduction technologies.

Our portfolio of Environmental Protection Agency (EPA) and California Air Resources Board (CARB) verified products provides effective solutions to address this need. We offer a full range of catalyst products for the control of carbon monoxide (CO), hydrocarbons (HC), PM and NOx in light and heavy duty applications. This market is highly driven by increasingly stringent worldwide regulatory standards and is sometimes funded by both public and private sources for early, voluntary compliance.
