The automobile industry has grown immensely over the last century- however- with the increase in use of internal combustion engine, the amount of pollutions produced by cars increased drastically. This is a very concerning subject as it is directly linked to global warming. The carbon di oxide which is given off as exhaust fumes traps the Sun’s heat in the Earth’s atmosphere giving a rise to global temperature- thus global warming. Also, these exhaust fumes contribute directly to acid rains. The carbon di oxide reacts with water in the atmosphere to form carbonic acid which then falls on to the Earth as acid. Acid rain has several devastating effects-like destroying plant and aqua life, causing skin diseases and even effecting buildings.
So what is the catalytic converter- it is basically a component of a car that converts the harmful exhaust fumes to harmless gases. Sounds pretty simple no? However, the procedure of how it does it is pretty tricky. It does it with a series of REDOX reaction – it catalyzes a REDOX reaction to be more precise.
The first widespread use of catalytic converter took place in the U.S. This was mainly done to obey the new law which forced them to limit pollutions. Every vehicles from 1975 were bound to have a catalytic converter.
The catalytic converter was invented by Eugene Houdry- who was a French engineer and a professional catalytic oil refinery guy. He is contributed to make the major breakthrough in the automobile industry which allowed cars and low pollution to exist in harmony.
So, what are the drawbacks of catalytic converter? The catalytic converter requires high temperature to operate for which it was at first placed close to the engine but was later removed due to several problems being associated with it. In conclusion a vehicle must be travelling long distances for the proper use of a catalytic converter.
