Resources Help Reduce Pollution in Catalytic Combustion
researcher at the University of Alberta is exploring
new dimensions of catalytic combustion. Dr Robert
Hayes, in collaboration with industrial stakeholders,
is developing new design methodologies for automotive
catalytic converters. Spearheading what is becoming
the most advanced research group in the world in
this area, Hayes is pushing the envelope in computer-based
catalytic converter design and modelling.
combustion is being used to burn components under
milder conditions that exist in standard homogenous
combustion. In primary combustion applications,
fuels are burned at lower temperatures and thus
fewer emissions of nitrogen oxides are produced.
In secondary applications, pollutants such as hydrocarbons
and carbon monoxide are burned to form carbon dioxide
and water thus reducing pollution levels.
catalytic converter will ultimately benefit society
as a whole. Environmentally, the reduction of harmful
emissions, especially from vehicle exhaust will be greatly
reduced. This new computer based design will also prove
to have more long-term effectiveness. Currently, automobile
catalytic converters tend to cease functioning after
a few years, but with this design, the converters
functionality will be long term.
