Detailed Product Description

Three -way catalysts will only give full conversion of each of these three pollutants in a gas stream containing a stoichiometric ratio of CO and NOx, as shown in the figure below.

There are many reaction pathways in a Three -way catalyst system, including those shown for the . The most important reactions for removing NOx can be summarised as:

2CO + 2NO -> 2CO₂ + N₂
[HC] + NO -> N₂ + CO₂ + H₂O
