A catalytic converter is an exhaust emission control device ... which have more precious metals than newer vehicles—sometimes worth more than the value of the car ...
Catalytic-converter-equipped vehicles have helped cut other air pollutants by more than 3 billion tons worldwide between 1975 and 2000; of this 1.5 billion short tons was in the United States. Automobiles meet emission standards that required reductions of up to 98+ percent for HC, 96 percent for CO, and 95 percent for NOx compared to the ...
[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 ...
An investigation uncovered that 13,000 catalytic converters have been stolen across central Ohio in 14 months, causing an estimated $19M in losses. Police: Theft ring stole some 13,000 catalytic ...
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.
Catalytic converters are targets for thieves because they contain palladium and other rare metals. In the run up to year 2000, the Russian supply of palladium to the global market was repeatedly delayed and disrupted; for political reasons, the export quota was not granted on time. [ 87 ]
Cutaway view of a metal-core catalytic converter. Of the 218 tonnes of platinum sold in 2014, 98 tonnes were used for vehicle emissions control devices (45%), 74.7 tonnes for jewelry (34%), 20.0 tonnes for chemical production and petroleum refining (9.2%), and 5.85 tonnes for electrical applications such as hard disk drives (2.7%).
Precious metals are rare, ... Platinum and palladium are key catalysts in hydrogenation reactions and emission-reducing catalytic converters, [7] ...
