CATALYTIC CONVERTER,
Our catalytic converter have good quality and competitive price, which are
suitable for cars in all types .
Our company has successfully developed many types of Universal Catalytic
Converter, which are suitable for cars in all types and meet the emission
standard. Of course, all kind of three-way Catalytic Converter can be explored
and produced according to the customers specific requirement.
The Catalytic Converter can eliminate 90% amount of the three main pollutants
(hydrocarbon, carbon monoxide and nitrous oxide).
primary structure of the catalytic converter
The catalytic converter is a device installed in the exhaust tube near the
engine where the gases are still at high temperature.
On the outside, it is made of a stainless steel shell(S304 or S409 material)
frequently covered with a heat-shield, that protects the lower parts of the
vehicle from the high temperatures reached
Inside the catalytic converter, there is a metal or ceramic honeycombed
substrate, on the surface of the substrate, coated with the precious metals such
as platinum, palladium and rhodium
Working theory of the catalytic converter
When the exhaust is passing through the exhaust pipe, CO HC and NOx ---the three
types of gas are passing through the clarifier of the reactor in the three-way
Catalytic Converter , the activity of the gas would be enhanced Under such a
high temperature, the CO would be oxidized into a gas without
color and poison, CO2; meanwhile the HC compound is turned into H2O and CO2;
finally the NOx is deoxidized into nitrogen,the three gases are turned into the
non-toxic gas to purify exhaust.
The three nocuous gas would be turned into the harmless gas to purify the
exhaust.
Oxidation reaction: HC+O2=H2O+CO2
Deoxidization reaction: NOx+HC+CO=N2
