The three-way catalytic converter, the most important off-board purification device installed in the exhaust system of a car, can transform harmful gases such as CO monoxide, HC hydrocarbons and NOx nitrogen oxides discharged from the exhaust of a car into harmless carbon dioxide, water and nitrogen through oxidization and reduction.
Since this catalytic converter can simultaneously convert the three main harmful substances in the exhaust gas into harmless substances, it is called ternary.
The three-way catalytic converter belongs to hazardous waste, which is more polluting to the environment. Only qualified recycling companies can recycle the catalytic converters, and it is illegal to sell them privately. So if you're a car owner, just keep an eye on your catalytic converter and leave the rest of the work to the end-of-life auto dismantling companies.
Common reasons for the acquisition:
1, the business recovery of three-way catalytic converter can be refurbished through the reprocessing, refurbishment can be sold after the second. Because the three-way catalytic converter is vital to the treatment of automotive emissions, and once damaged can only be replaced, so the refurbished three-way catalytic converter through the second-hand trade can also be sold at a good price.
2, three-way catalytic converter contains many rare metals (such as Pd palladium, Rhodium, Pt platinum), rare metal prices are more expensive, these rare metals through the refining can be sold, so as to gain profit.
Legal basis:
Article 42 of the Environmental Protection Law of the People's Republic of China*** and the State of China Article 42 Enterprises, institutions and other producers and operators that emit pollutants shall take measures to prevent and control the production of waste gases, wastewater, waste residues, medical wastes, dusts, malodorous gases, radioactive substances, and noise, vibration, optical radiation, electromagnetic radiation and other pollution and hazards to the environment. Enterprises and institutions discharging pollutants shall establish a responsibility system for environmental protection, and clarify the responsibilities of unit heads and relevant personnel. Key emission units shall install and use monitoring equipment in accordance with relevant state regulations and monitoring specifications, ensure the normal operation of monitoring equipment, and keep original monitoring records. It is strictly prohibited to discharge pollutants illegally through concealed pipes, seepage wells, seepage pits, irrigation or tampering, falsification of monitoring data, or improper operation of pollution prevention and control facilities to avoid supervision.
