There are three different types of Cat-Cons. The first type is the oxidation catalyst. It reduces harmful pollutants such as carbon monoxide (CO) and fuel hydrocarbons (HC) in the exhaust. Simultaneously, it often uses a secondary air injection. However, the oxidation catalyst only reduces a ...
The chemical processes that occur inside a catalyst can vary depending on the specific catalyst design and the pollutants that it is designed to reduce. However, in general, the following chemical processes occur in a catalyst: Oxidation: Carbon monoxide (CO) and hydrocarbons (HC) are oxidized b...

Oxidation of Alcohol If you strip off hydrogens from the right carbon of ethanol in the presence of oxygen, you get acetic acid, the main component in vinegar. The molecular structure of acetic acid looks like this: where C is carbon, H is hydrogen, O is oxygen, the hyphen is a single...
a mixture of sulfuric acid and nitric acid is used as raw materials. Among them, the role of sulfuric acid is: (1) as a catalyst that can generate nitro -ions; (2) to have a certain pose ability to cellulose and accelerate the chemical response rate; (4) Improve the stability of the...
In the catalytic converter, there are two different types of catalyst at work: a reduction catalyst and an oxidation catalyst. Both types consist of a ceramic structure coated with a metal catalyst, usually platinum, rhodium and/or palladium....
