Quick Summary

A dual-bed catalytic converter is a component in automobiles designed to reduce harmful emissions from internal-combustion engines. It contains a honeycomb structure coated with catalysts through which exhaust gases pass. In a dual-bed system, exhaust gases are first treated to reduce nitrogen oxides. Then, with added air, they are oxidized to eliminate carbon monoxide and unburned hydrocarbons, converting them into water vapor and carbon dioxide. This process helps to control pollution by transforming noxious gases into less harmful substances.12
