Background

The three-way catalyst is installed outside the automobile exhaust system and can convert harmful gas, such as CO, HC, NOx, etc. exhausted from automobile exhaust into harmless carbon dioxide, water and nitrogen via oxidation and reduction. When high-temperature automobile exhaust passes through the purification device, the purifying agent in the three-way catalyst enhances the activity of three gases of CO, HC and NOx to promote the three gases to carry out certain oxidation-reduction chemical reaction, wherein CO is oxidized into colorless and nontoxic carbon dioxide gas at high temperature; HC compounds are oxidized at high temperature to water (H20) and carbon dioxide; NOx is reduced to nitrogen and oxygen. Three kinds of harmful gases are changed into harmless gases, so that the automobile exhaust can be purified. The catalyst can simultaneously convert three main harmful substances in the exhaust gas into harmless substances, so the catalyst is called as a ternary catalyst.

The three-way catalytic reactor resembles a muffler. The outer surface of the cylinder is made of double-layer stainless steel sheets into a cylinder shape. The double-layer thin plate interlayer is filled with heat insulating materials, namely asbestos fiber felt. The inside of the tank is provided with a purifying agent in the middle of the reticular clapboard. The purifying agent consists of carrier and catalyst.
