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.
Used catalytic converters can sell for anywhere from $25 to $1,000, depending on the metals content, which varies by a vehicles make and model, according to Scott Vollero and Christopher Gaines ...
In catalytic converters used on automobiles, the combustion of leaded gasoline produces elemental lead, lead(II) oxide, lead(II) chloride, and lead(II) bromide. Lead alloys with the metals present in the catalyst, while lead oxides and halides coat the catalyst's surfaces, reducing the converter's ability to reduce NOx emissions.
The catalytic converter is a device placed in the exhaust pipe, which converts hydrocarbons, carbon monoxide, and NO x into less harmful gases by using a combination of platinum, palladium and rhodium as catalysts. [16] There are two types of catalytic converter, a two-way and a three-way converter.
Commercial selective catalytic reduction systems are typically found on large utility boilers, industrial boilers, and municipal solid waste boilers and have been shown to lower NO x emissions by 70-95%. [1] Applications include diesel engines, such as those found on large ships, diesel locomotives, gas turbines, and automobiles.
Catalytic converters in cars intend to break down the pollution of exhaust gases using a catalyst. Scrubbers in ships intend to remove the sulfur dioxide (SO 2) of marine exhaust gases. The regulations on marine sulfur dioxide emissions are tightening, however only a small number of special areas worldwide have been designated for low sulfur ...
The motion, which passed by a vote of 8-to-4 last Tuesday, stipulated that nearly 8,000 catalytic converter components had been stolen across Los Angeles in 2022, a 728 percent spike since 2018.
When the catalytic converter is cold, air injected at the upstream point burns with the deliberately rich exhaust so as to bring the catalyst up to operating temperature quickly. Once the catalyst is warm, air is injected to the downstream location — the catalytic converter itself — to assist with catalysis of unburned hydrocarbons.
