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.
The purpose of any catalytic converter is to reduce harmful emissions from the exhaust of a properly tuned combustion engine. It accomplishes this through a combination of heat and aprecious metal catalyst that causes the harmful emissions to either oxidize or reduce to safe elements in the exhaust flow.irst, the carbon deposits prevent the catalytic converter from reducing harmful emission in the exhaust flow. And second, the carbon deposits clog the pores in the ceramic catalyst and block exhaust flow, increasing backpressure and causing heat and exhaust to back up into the engine compartment.
