How Much Platinum is in a Catalytic Converter?

Have you ever wondered how much Platinum is inside a catalytic converter?

Catalytic converters are an essential component of automotive exhaust systems. They are responsible for cleaning up the toxic pollutants from engine exhaust, making them more eco-friendly, and reducing overall air pollution. Among other precious metals, catalytic converters contain Platinum, which helps reduce harmful emissions.

Since Platinum plays such an important role in catalytic converters, it is vital to know how much of this precious metal is used in each unit. This article will explore how much Platinum can be found inside a typical catalytic converter, its tentative worth, and how you separate it from the converter.

What is Platinum, and how it helps with oxidation?

Platinum is a rare and valuable metal with many uses, including catalytic converters. It helps reduce the number of harmful emissions from engine exhaust by aiding in oxidation. Oxidation is a chemical reaction when oxygen combines with other elements, such as carbon monoxide or hydrocarbons, to form less-toxic compounds. Platinum helps to speed up this process, making it more efficient and effective.

How much Platinum is in a Catalytic Converter?

The amount of Platinum used in a catalytic converter can vary depending on the type and size of the vehicle, as well as the manufacturer. However, most converters contain between 3 grams to 7 grams of Platinum. It may not seem like a lot, but it is enough to make a significant difference in the amount of emissions that are released from a vehicle.

In addition to Platinum, catalytic converters contain other precious metals such as palladium, rhodium, and iridium. These metals help further reduce the harmful emissions from engine exhaust.

Knowing how much Platinum is inside a catalytic converter can benefit both car owners and mechanics. It can ensure that the converter is functioning properly and providing the necessary protection against harmful emissions. Additionally, understanding how much Platinum is used in a catalytic converter can help car owners make informed decisions when purchasing replacement parts.

How much is the platinum worth in a catalytic converter?

The amount of Platinum in a catalytic converter is typically worth between $100 and $300. This value can vary depending on the market price of Platinum, as well as the size and type of vehicle. Additionally, some catalytic converters may contain other precious metals, such as palladium, rhodium, or iridium, which can also increase the overall value of the converter.

The platinum price in January 2023 stands at $34,376.22. It means 3 grams of Platinum, if present in the catalytic converter, costs around $ 100. Coupled with other precious metals, it attracts the attention of thieves with a higher valuation.

How do you get Platinum out of a catalytic converter?

The process of extracting Platinum from a catalytic converter involves hydrometallurgical processes. This process involves using specialized equipment to break down the converter into its parts and separate and process it. The Platinum is then extracted from the other metals and materials in the converter, such as palladium, rhodium, and iridium.

The Platinum Group metals (PGM) are primarily located at the surface of the inner cell. Along with Hydrogen thermal pre-treatment, adding H2O2 as an oxidant agent helps reduce the pollutant gases. Upto 95% of PGM, are successfully recovered with different compositions of reagents.

Once the Platinum has been extracted, it can be sold to refineries or other buyers for a profit. Platinum recycling is an important part of the automotive industry, as it helps to reduce waste and conserve resources.

Why is Platinum used in Catalytic converters?

Platinum is particularly important in this process, as it collects oxygen atoms and allows them to bind to carbon monoxide molecules. This binding turns the carbon monoxide into carbon dioxide, a much less harmful gas.

Platinum in catalytic converters is also beneficial due to its high resistance to heat and oxidation. This makes it ideal for use in these devices exposed to extreme temperatures and harsh environmental conditions. Furthermore, Platinum is one of the most abundant elements on Earth and is relatively easy to obtain compared to other precious metals used in catalytic converters.

All these factors make Platinum an excellent choice for use in catalytic converters and ensure they remain effective at reducing vehicle emissions.

How much are old catalytic converters worth?

The value of old catalytic converters can vary depending on the type and size of the converter and the number of precious metals it contains. Generally speaking, a standard catalytic converter can be worth anywhere from $50 to $200, while a larger or more complex converter may be worth up to $500 or more. Additionally, the value of a catalytic converter can increase significantly if it contains a large number of precious metals.


Platinum recycling is also an important part of the automotive industry, as it helps to reduce waste and conserve resources. The value of the Platinum inside a catalytic converter can range from $100 to $290 depending on market prices and the type of vehicle. Knowing how much Platinum is in a catalytic converter can help car owners and mechanics ensure that their vehicles run efficiently and safely.

In conclusion, catalytic converters contain a small but significant amount of Platinum, which helps to reduce the amount of harmful emissions from engine exhaust.
