which precious metals are contained in the catalyst and why are they important

Exhaust gas neutralizers contain a significant amount of precious metals, which is the reason for their high cost. Even after prolonged use, these components retain their value, so the old converter can be sold profitably through the service Autocatalyst, where experts will assess the content of precious metals.

Composition and Cost

Car owners are often surprised by the cost of a new gas converter. For example, you can estimate the value of a used catalytic converter from Cadillac on the page, where they offer a decent compensation for the precious metals contained in it.

The Role of Platinum in Purification

Platinum acts as the main component in the composition of the gas converter. This noble metal ensures the efficient oxidation of carbon monoxide and unburned hydrocarbons. The platinum content in modern neutralizers can reach several grams, which determines their high cost.

The Importance of Palladium

In gas purifiers, palladium works in tandem with platinum. The main features of operation include:

  • The process of neutralizing toxic compounds begins at lower temperatures due to palladium’s unique properties. The metal retains its catalytic properties even with significant temperature fluctuations. High resistance to thermal stresses ensures a long service life of the component. Palladium effectively interacts with other precious metals, enhancing their cleaning properties. If the car is operated properly, the metal is practically not consumed.
  • The cost of palladium on the world market is constantly growing, which increases the value of spent converters. The technology of metal extraction makes it possible to obtain the metal in its pure form for reuse. Modern recycling methods ensure a high percentage of palladium recovery from used purifiers. Demand for this metal in the automotive industry continues to increase.

Functions of Rhodium

Rhodium is among the most expensive metals of the platinum group. In a gas converter, it is responsible for reducing nitrogen oxides to safe compounds. Despite its small content, its role is indispensable for the efficient operation of the entire purification system.

Metal Interaction

The combination of three precious metals creates a unique catalytic effect. Each component performs its own function, and their combined action ensures maximum efficiency of exhaust gas purification.

Prospects of Use

The development of converter production technologies is aimed at optimizing the content of precious metals. Engineers are working on increasing the efficiency of their use while reducing their quantity. However, it is not yet possible to completely abandon the use of platinum, palladium, and rhodium.

Conclusion

Understanding the role of precious metals helps you realize the real value of an exhaust gas converter. If replacement is necessary, it is not worth throwing away the old component – it can be profitably sold through specialized services like Autocatalyst, receiving compensation for the precious metals contained.

The development of recycling technologies allows efficient extraction of valuable components, facilitating their reuse in the production of new cleaners.
