Various chemical reactions can be promoted by catalysis, but where the aim is to improve air quality the most important reaction is oxidation. The majority of air pollutants are organic in nature (i.e. they contain carbon) and can be oxidised into harmless substances such as carbon dioxide and water.
Most oxidation catalytic converters use coatings based on platinum and/or palladium, which are effective at temperatures as low as 225oC. The structural part of a catalytic converter is known as a ‘substrate’, the main purpose of which is to provide a large surface area onto which the catalytic coating can be applied.
Whitebeam supplies catalytic converters based on a variety of substrates depending on the application and we are happy to advise customers which is the most suitable for their application based on our many years of experience in this field.
