How much rhodium is in the average catalytic converter

A catalytic converter is a device that helps to convert harmful emissions from an engine into harmless gases. Rhodium is one of the metals that are used in catalytic converters.

It is very effective in converting carbon monoxide and hydrocarbons into carbon dioxide and water vapor. But how much rhodium is in a catalytic converter?

The amount of rhodium in a catalytic converter is up to 2 grams, with most converters having less than a gram. This may seem like a very small amount, but keep in mind that Rhodium has a staggering price of around $450 per gram!

What Is Rhodium?

Rhodium is a chemical element with the symbol Rh and atomic number 45. It is a rare, silvery-white, hard, and chemically inert transition metal. Rhodium is a member of the platinum group.

It has only one naturally occurring isotope, 103Rh. Naturally occurring rhodium is found in nickel ores from Sudbury, Ontario, and in the copper-nickel sulfide mineral rhodochrosite.

Small but commercially important quantities of rhodium are found in the platinum ore ferroplatinum and palladium ores.

It is one of the rarest and most valuable precious metals. Rhodium is used in jewelry as a plating to give it a bright, reflective finish. It is also used in catalytic converters to control emissions.

Rhodium was discovered in 1803 by William Hyde Wollaston in one of the platinum ores found in South America. He used crude platinum ore from Peru and Guatemala and produced purer samples of the metal.

He named the element after the Greek word for rose, rhodon. Rhodium was first isolated as a metal in 1828 by two chemists, Jacob Berzelius and Jöns Jakob Berzelius, in Stockholm.

Catalytic Converters Types

There are two main types of rhodium-based catalytic converters:

Flow-Through

The flow-through converter is the more common type. It uses a combination of rhodium and platinum to catalyze the reaction between carbon monoxide and nitrogen oxides, converting them into harmless nitrogen gas and water vapor.

Honeycomb

The honeycomb converter is less common, but it is more efficient. It uses a rhodium-coated honeycomb to catalyze the reaction between carbon monoxide and nitrogen oxides.

The honeycomb converter is more expensive, but it lasts longer and does not need to be replaced as often.

Catalytic converters contain small amounts of rhodium to promote the reduction of harmful emissions from engines. Rhodium is a precious metal that is used in catalytic converters because of its ability to speed up chemical reactions while being resistant to poisoning.

Rhodium is a noble metal that is highly resistant to corrosion and has a low melting point, making it ideal for use in catalytic converters.

In addition, rhodium has a high affinity for oxygen, which makes it an effective catalyst for the reduction of harmful emissions such as carbon monoxide and nitrogen oxides.

Types of Metals Found in a Catalytic Converter

Catalytic converters are devices used to convert exhaust gas emissions from an internal combustion engine into less harmful substances. For a catalytic converter to work properly, it must contain one or more metals that can catalyze the reaction. The most common catalyst metals are:

Platinum

Platinum is the most active catalyst and is effective at reducing emissions from both gasoline and diesel engines. Platinum is also the most expensive catalyst metal. This makes it the metal of choice for luxury cars and other high-end vehicles.

Palladium

Palladium is less active than platinum but can still be used to reduce emissions from gasoline and diesel engines.

Palladium is less expensive than platinum making it a popular choice for use in mass-produced vehicles. However, palladium is still more expensive than other catalyst metals.

Rhodium

Rhodium is least active than palladium but can still be used to reduce emissions from gasoline and diesel engines. It has the highest resistance to poisoning making it useful for certain types of engine applications.

Rhodium is less expensive than palladium but is still more expensive than other catalyst metals.

The Value of Rhodium

The value of Rhodium has seen a significant increase in recent years due to the metal’s rarity and its use in catalytic converters.

The price of rhodium per gram is expected to be $495.12 in 2022, which is equivalent to approximately $16,000 per ounce. This makes it one of the most costly precious metals.

The premium cost is due to its scarcity and distinct characteristics. Rhodium has a high melting temperature and resists corrosion well.

Rhodium’s high cost is due to its scarcity. Only a few mines produce rhodium, and the majority of it comes from South Africa. As a result, the supply is extremely limited, and prices are likely to continue increasing in the future.

Types of Cars With Precious Metals Inside the Catalytic Converter

The amount of rhodium and other metals in a catalytic converter can vary depending on the type of vehicle it is used in. Cars with larger engines generally have more metal in their converters than smaller cars.

SUVs and trucks also tend to have more metal because of their size and weight. The metals inside a converter work to reduce emissions from a car’s engine. The vehicles containing these metals include:

• The Mercedes-Benz S600 has a catalytic converter that contains around $400 worth of palladium.
• The Audi A8 L W12 Quattro has a converter with $700 worth of platinum.
• The BMW 760iLi contains a converter with $1,300 worth of rhodium

Extract Rhodium Out of the Converter

There are a few ways to go about this:

1. Aqua Regia Process

This process involves the use of a mixture of hydrochloric acids and nitric acids. The mixture is then heated to a temperature of around 70 degrees Celsius.

This causes the rhodium to dissolve and be separated from the other metals in the converter. This process can be dangerous and is best left to the professionals.

2. Electrolysis Process

This process involves passing an electric current through the converter. The rhodium is then attracted to the electrodes and can be separated from the other metals. This process is slower compared to aqua regia but is much safer.

Recover Value From an Old Catalytic Converter

There are many reasons why people use scrap catalytic converters to recover value from the precious metals inside. Rhodium is one of those metals, and it’s worth quite a bit.

The process for recovering the rhodium is quite simple. The converter is placed in an acid bath, which dissolves the metal and separates it from the other metals in the converter. The rhodium is then purified and sold.

The value earned from selling rhodium can be significant, and it’s a great way to recycle an old converter. If you have an old converter sitting around, it’s worth considering selling it for the rhodium.
