“How much palladium is in a catalytic converter?” Palladium, platinum, and rhodium are the three primary metals used in catalytic converters. They promote oxidation reactions that neutralize pollutants like carbon monoxide and uncombusted hydrocarbons. Together, they transform these nasty pollutants into harmless gases that don’t damage the environment.
Palladium in a catalytic converter
Palladium is a precious metal that is used for many different things, including jewelry, flutes, and automotive catalytic converters. It is a rare metal that is found in relatively small quantities, and is primarily produced in Russia. The price of palladium spiked in 2014 when the Russian government invaded Ukraine, but it has since dropped back to normal prices. However, it is still five times more expensive than it was a few years ago.
Cars have catalytic converters that contain palladium in varying amounts, depending on their make and model. The average car has between two and seven grams of palladium in its converters. Larger luxury cars have ten to twelve grams of palladium per converter. Smaller economy cars may contain only one or two grams.
The metal is used in the catalytic converter in order to convert harmful emissions into less harmful ones. It is also used in fuel cells. Fuel cells use palladium as a catalyst to mix hydrogen with oxygen to produce electricity.
Rhodium
If you’re in the market for a new or used catalytic converter, it’s time to start wondering about how much palladium is in the catalytic converter. Catalytic converters are important parts of your car’s exhaust system, and they can be worth hundreds or even thousands of dollars. Besides being expensive, catalytic converters also have some strange properties.
Platinum, as well as rhodium, reduce nitrogen oxide emissions that cause acid rain and smog. Palladium and platinum also promote oxidation reactions, and they neutralize carbon monoxide and uncombusted hydrocarbons. This helps convert these nasty gases into harmless byproducts.
Catalytic converters contain two to seven grams of palladium, depending on the type and model. Smaller models contain less palladium than large ones. Rhodium and platinum are used to balance out the amount of palladium.
Platinum
Platinum is one of the most precious metals on the planet and is used in catalytic converters for vehicles. It is a highly conductive metal with excellent catalytic properties and is used for many industrial applications. Around one-third of the world’s supply of platinum is used for this purpose. Its melting point is very high and it is a highly recyclable metal.
A catalytic converter is an important part of an automobile. It helps to keep the air free of harmful substances while maintaining the air quality. Because of its high value, platinum is one of the most sought-after precious metals. Fortunately, recovering platinum from the catalytic converter is easy, but it is best to consult with a professional.
The amount of platinum and palladium in a catalytic converter varies between vehicles, but a standard one contains around five grams. Other precious metals commonly used in catalytic converters include rhodium and palladium, but not gold.
Demand for palladium
The catalytic converter is a major demand driver for palladium. The metal is used in these catalysts to reduce the toxic emissions released from car engines. The catalysts are layered in ceramic beads. The high surface area of the beads enables maximum contact between the platinum-group metals and the exhaust gases.
Palladium is widely used for several industrial applications, including in fertilizer manufacturing. However, its main use in the automotive sector is as an active component of catalytic converters. In 2017, automotive catalytic converters accounted for 85 per cent of total demand for palladium, using up 8.6 million ounces of the metal. The catalysts are expensive and will degrade over time.
The demand for palladium in catalytic converters has increased due to the demand for cleaner burning cars. The global auto industry is feeling pressure to reduce the harmful emissions from vehicles, including ICEs. Governments are passing stricter pollution regulations, and consumers are demanding cleaner-burning cars.
