How much Precious Metal is in a Catalytic Converter

If you do not know what a catalytic converter is, let us tell you about it. It is considered one of the important parts of your car’s emission system. It is located near the engine and plays a vital role in changing the environmentally damaging pollutants and dust particles to toxic gases. There are different types of materials available in a catalytic converter among which platinum is one.

You must be thinking about how much precious metal is in a catalytic converter. If you want to know the answer to this query, you need to go through this guide. It provides you with detailed information about a catalytic converter, its importance, and the precious metal that is present in this converter. You will come to know about its amount and the factors it depends upon.

Importance of a Catalytic Converter

There is a great importance of a catalytic converter in a vehicle as it breaks down the harmful molecules and split the particles when they leave the engine. These harmful pollutants are not mixed with the air. You may be thinking it is a difficult task but it is not that difficult for a catalytic converter of platinum.

Let us tell you that metal has been installed inside your car which also consists of an output and input pipe. A series of chemical reactions take place to alter the gases and convert them into those gases that are not harmful to the environment. For your information, air pollution is not eliminated by catalytic converters but they can reduce the level of air pollution to some extent.

Materials Included in Catalytic Converter

The materials included in a catalytic converter depend upon its model. Let us tell you that a standard catalytic converter consists of rhodium, palladium, and platinum. You must be thinking about how much precious metal is in a catalytic converter, let us tell you that the amount of each material is different in the catalytic converter.

Commonly, there are two to seven grams of palladium, one to two grams of rhodium, and three to seven grams of platinum in a standard catalytic converter. Let us tell you that these platinum group metals are responsible for converting nitrogen oxides, hydrocarbons, and carbon monoxide gas into less harmful gases.

Purpose of Catalysts

You must be wondering what are the catalysts present in a catalytic converter. Let us enhance your knowledge that the materials named rhodium, palladium, and platinum as considered as the catalysts present in a catalytic converter. The working of each catalyst is different but they aim to break down harmful molecules of gases into less harmful ones to protect the environment from air pollution.

The purpose of rhodium in the catalytic converter is to convert the carbon monoxide and nitrogen oxides into carbon dioxide and nitrogen. Platinum aims to oxidize the hydrocarbons and carbon monoxide by mixing with the water vapors. It is best under oxygen-excessive conditions.

On the other hand, the purpose of palladium is to remove carbon mono oxide, hydrocarbons, and other harmful gases present in the exhaust system. 90% of the harmful gases are converted into less harmful molecules by palladium present in the catalytic converters.

Benefits of a Catalytic Converter

We know about the major benefit of a platinum catalytic converter as it reduces the level of air pollution in the environment by reducing the toxic gases into less harmful ones. It is beneficial in decreasing the emissions of hydrocarbon by about 87%, nitrous oxide by 62%, and carbon monoxide by 85% which in turn results in increasing the life of your vehicle.

You can take care of your health by installing a catalytic converter in your car. It shows that you are not only concerned about your health but also the health of other people. The use of a catalytic converter also reduces the chances of getting allergies such as flu, cough, lungs problems, breathing problems, etc.

Need of Replacing a Catalytic Converter

You need to replace your catalytic converter when it becomes old because it is not able to perform the conversion process very well. It is recommended to replace the catalytic converter after at least ten years. Moreover, if it has been damaged or broken, it would be best to replace it with a new one immediately to avoid future problems.

If you notice the catalytic converter is clogged, contaminated by oil, or damaged physically, you must hire a technician to get it fixed or install a new one. The emission system may also be affected if the catalytic converter is damaged. So, it would be best to have a look at the emission system completely to check whether the entire system is working properly or not.
