[11] [14] The codes on catalytic converters identify the make, model and place of origin of catalytic converters, which in turn identify their value, due to variation in state emission laws. [ 11 ] [ 18 ] As an example, GD3 EA6 denotes a Toyota Prius manufactured between 2004 and 2009; [ 11 ] [ 14 ] at the peak of the PRP metal prices, its high ...
A three-way catalytic converter on a gasoline-powered 1996 Dodge Ram Simulation of flow inside a catalytic converter. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction.
The primary use of this element is in automobiles as a catalytic converter, changing harmful unburned hydrocarbons, carbon monoxide, and nitrogen oxide exhaust emissions into less noxious gases. Of 30,000 kg of rhodium consumed worldwide in 2012, 81% (24,300 kg) went into this application, and 8,060 kg was recovered from old converters.
Monolithic catalyst supports are extruded structures that are the core of many catalytic converters, [1] most diesel particulate filters, and some catalytic reactors. Most catalytic converters are used for vehicle emissions control. Stationary catalytic converters can reduce air pollution from fossil fuel power stations.

Mooney (right) at the award ceremony for the National Medal of Technology and Innovation for the invention, application and commercialization of the three-way catalytic converter (2003) Mooney was elected a Fellow of Society of Automotive Engineers (SAE) in 1990 for his efforts in exhaust emission control.

Carl Donald Keith (May 29, 1920 – November 9, 2008) was a chemist who was inventor of the three-way catalytic converter, which has played a dramatic role in reducing pollution from motor vehicles since their introduction in the mid-1970s.
It is used in catalytic converters ("three-way catalytic converter") for the minimisation of CO emissions in the exhaust gases from motor vehicles. When there is a shortage of oxygen, cerium(IV) oxide is oxidizes carbon monoxide to the benign dioxide: [ 3 ] [ 4 ]
