What can be done after automobile three-way catalytic recovery?

The carrier part of the three-way catalytic converter for refining precious metals is porous ceramic material, which is installed in a special exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself, but is covered with a layer of precious metals such as platinum, rhodium and palladium. Scrapped three-way catalytic converters can be recycled to extract precious metals such as platinum, rhodium and palladium.

Refining process of three-way catalytic converter;

1, the metal shell needs to be removed, usually by large crocodile hydraulic scissors or other tools.

2. Go to the production line to select materials (many impurities need to be removed).

3. Crushing processing.

4. Adding various chemical raw materials to refine precious metals at high temperature. Because refining requires certain technical requirements, novices suggest starting with recycling and renovation.

Extended data:

With the improvement of domestic emission standards, it is not enough for cars to meet the annual inspection standards, except upgrading engine technology. The three-way catalyst also needs to spray precious metal slurry inside the honeycomb ceramic carrier, and its main components are platinum, rhodium and palladium.

These precious metals play the role of purifying agents, and can convert harmful gases in automobile exhaust such as carbon monoxide, carbon monoxide, hydrocarbons and nitrogen oxides into harmless carbon dioxide, water and nitrogen through oxidation and reduction. This catalyst is called ternary because it can convert three main harmful substances in waste gas into harmless substances at the same time.
