Document Title: Catalysis to Control Vehicle Exhaust Emissions
Category: Energy Production and Conservation, Pollution Prevention and Waste Reduction
Media Type: Graphics
Date of Image/Photo: Autumn 2002
Background: Vehicle exhaust, loaded with nitric oxides, flows into the non-thermal plasma reactor, where it is converted into nitrogen dioxide. A catalyst is then responsible for a chemical reaction that reduces nitrogen dioxide into harmless nitrogen gas. An optional filter also reduces particulate matter. PSA Peugeot CitroŽn installed this system in their Peugeot 206 environmental demonstration model.
