A three-way catalytic converter makes use of two catalysts to convert harmful gases to harmless gases. They are: 1  Reduction Catalyst and. 2  Oxidation Catalyst.he gases that finally come out of the catalyst chamber are N 2, CO 2, and H 2 O. 3-way catalytic converters are so named because they are capable of eliminating three pollutants â NO x, CO and HC.
X, x=1,2,3) and carbon monoxide (CO) from the combustion residues before they are released into the environment. It is called a catalytic converter because it converts CO into ubiquitous CO 2 and NO X into N 2 and O 2 through chemical reactions on a solid catalyst.A catalyst is a chemical compound that helps the reaction to occur faster by reducing the activation energy barrier of the reaction.n the case of the catcon, the catalyst is a solid platinum (Pt) or palladium (Pd)surface unto which reactants from the gaseous phase adsorb and react. This process of a reaction being assisted by a catalyst that is in a phase different from the reactants phase is known as heterogeneous catalysis.
