Oxidation Catalytic Converters Overview

Oxidation Catalytic ConvertersCatalysis is a branch of chemistry where certain chemicals known as 'catalysts' are used in order to encourage or promote reactions between other chemicals. A key point to appreciate is that the catalysts themselves are not consumed by the reactions, they merely help them along. Therefore a catalyst can theoretically last forever. The name 'catalytic converter' is applied to a practical device which has been designed to make use of catalytic technology i.e. it enables the benefits of catalysis to be obtained in real-life situations.

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.
