A catalytic converter is an exhaust emission control device that
reduces toxic gases and pollutants in exhaust gas from an internal
combustion engine into less-toxic pollutants by catalyzing a redox
reaction (an oxidation and a reduction reaction). Catalytic
converters are usually used with internal combustion engines fueled
by either gasoline or diesel—including lean-burn engines as well as
kerosene heaters and stoves.
Application of catalytic converter:
Although catalytic converters are most commonly applied to exhaust
systems in automobiles, they are also used on electrical
generators, forklifts, mining equipment, trucks, buses,
locomotives, and motorcycles. They are also used on some wood
stoves to control emissions. This is usually in response to
government regulation, either through direct environmental
regulation or through health and safety regulations.
Catalytic converters require a temperature of 800 degrees
Fahrenheit (426 °C) to efficiently convert harmful exhaust gases
into inert gases, such as carbon dioxide and water vapor.
Therefore, they are placed as close to the engine as possible.
A 2-way (or "oxidation", sometimes called an "oxi-cat") catalytic
converter has two simultaneous tasks:
Oxidation of carbon monoxide to carbon dioxide: 2 CO + O2 → 2 CO2
Oxidation of hydrocarbons (unburnt and partially burned fuel) to
carbon dioxide and water: CxH2x+2 + [(3x+1)/2] O2 → x CO2 + (x+1)
H2O (a combustion reaction)
This type of catalytic converter is widely used on diesel engines
to reduce hydrocarbon and carbon monoxide emissions. Because of
their inability to control oxides of nitrogen, they were superseded
by three-way converters.
Three-way catalytic converters (TWC) have the additional advantage
of controlling the emission of nitric oxide (NO) and nitrogen
dioxide (NO2) (both together abbreviated with NOx and not to be
confused with nitrous oxide (N2O)), which are precursors to acid
rain and smog.
Since 1981, "three-way" (oxidation-reduction) catalytic converters
have been used in vehicle emission control systems in the United
States and Canada; many other countries have also adopted stringent
vehicle emission regulations that in effect require three-way
converters on gasoline-powered vehicles. The reduction and
oxidation catalysts are typically contained in a common housing;
however, in some instances, they may be housed separately. A
three-way catalytic converter has three simultaneous tasks.
