The birth and history of the three-way catalytic converter

When we discuss the three-way catalytic converter, most people will love and hate itSome enthusiasts find the catalytic converter a nuisance, but it is a vital component of your car’s emissions controlReduce the entry of pollutants and exhaust gases into the air, causing damage to the respiratory tract of humans, animals and plants

Speaking of the birth of the three-way catalytic converter, it was not long ago, the first prototype of the three-way catalytic converterThe first prototype of a catalytic converter for these purposes was developed in France and was first patented by “Eugène Jules Houdry” (Domont, France, April 18, 1892 – Upper Darby, Pennsylvania, July 18, 1962).

This mechanical engineer founded Oxy-Catalyst Company in the United States, which first developed stack catalysts and later for forklifts, which used low-grade unleaded gasoline. Later, he developed the automobile catalytic converter.

It has to be said that this is really a great invention, and it has played a vital role in reducing exhaust pollution emissions.

When the high-temperature automobile exhaust gas passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, and promote them to undergo a certain oxidation-reduction chemical reaction, in which CO is oxidized at high temperature to become non-toxic. Color, non-toxic carbon dioxide gas; HC compounds are oxidized to water (H20) and carbon dioxide at high temperature; NOx is reduced to nitrogen and oxygen. Three kinds of harmful gases become harmless gases, so that the automobile exhaust can be purified.

For his design, he received U.S. Patent 2,742,437 in 1956. This device quickly spread throughout the automotive world, and now a staple of emissions control, and is incorporated into almost every modern exhaust system

After the improvements made by Engelhard Corporation, culminating in 1973, the first catalyst intended for mass production appeared. By 1975, nearly every car in the United States was installed to comply with EPA regulations

The three-way catalytic converters mainly produced by our company are mainly classified into 500 types such as Volkswagen, Audi, Buick, Chevrolet, Mercedes-Benz, BMW, Citroen, Renault, Honda, Toyota, Mitsubishi, Nissan, Subaru, Land Rover, Hyundai, American Jeep series,and so many kind of universal TWC

In modern times, almost all cars will be equipped with three-way catalytic converters, and different models of three-way catalytic converters are installed differently, usually with different models, sizes and materials 

The catalytic converter is one of the important parts that have an effective role in the performance of the car and the preservation of the environment. As all modern cars contain a catalytic converter in the exhaust-system that is placed before the muffler to clean the exhaust gases by treating and disposing of harmful gases by oxidizing them and converting them into gases that are not harmful to the environment

Simple explanation, catalytic converters oxidize (burn) the HC and CO emissions that are released into the exhaust system. The high temperature (about 800 degrees Celsius) ignites these emissions and converts them into harmless gases (carbon dioxide and water vapor)
