How car catalytic converters work

Modern vehicles have adapted to run on clean, i.e. lead-free petrol. Even so, vehicles must use an exhaust cleaning system to avoid environmental pollution. For this reason, they must incorporate a catalytic oxidation catalytic converter in their exhausts that allows a catalytic oxidation of the gases that pass through the exhaust, so that they react to reduce the amount of toxic gases in the environment. In this article, we will look at how these car catalytic converters work.

Car catalytic converter

Car catalysts use monolithic catalyst technology. This type of heterogeneous catalyst has the particularity of having channels designed to allow a fluid to pass through them and facilitate chemical reactions on the surface, forcing the creation of the desired product at a faster rate than would normally be possible.

Car catalytic converters are made of ceramic materials and metals that promote reactions on the surface of the microchannels. In the following video, we will see how these car catalytic converters work:
