How to Calculate the Value of a Catalytic Converter? After knowing the value of each metal present inside a catalytic converter, you also need to answer the following questions: What is the brand of the car? What is the reference of the catalytic converter? What is the weight of the catalytic converter without the shell?

These cars, their catalytic converters use high contents of platinum, making them expensive. Platinum is a silvery chemical element and member of the six transition compounds in group viii in the periodic table.
It belongs to a group of platinum metals: rhodium, osmium, platinum, ruthenium, rhodium, and iridium. The metal has the symbol Pt, atomic number seventy-eight with an atomic weight of It is heavy, precious, soft, malleable, and silver-white metal with a high melting point.
It is associated with gemstones such as olivine and chromite. The metal is found as grains and nuggets, and its pure nature is unknown since well-formed platinum crystals are rare to find. Platinum becomes so expensive because it is a precious metal, and precious metals are priced by weight. Since platinum is heavier or denser than gold, it becomes so expensive. The other reason is that platinum is more valuable than gold since it is a rare metal to find.
Moreover, the extraction process for platinum is more expensive than other metals. This is because platinum has a higher melting point, making its extraction expensive due to the high amount of energy required to extract it.
Additionally, there has been a higher demand for heavy-duty Chinese vehicles which has, in turn, increased the demand for platinum, increasing its value day by day.
The price of platinum today varies based on the metric units used. Platinum is a silvery-white precious metal used in catalytic converters to oxidize hydrocarbons and carbon monoxide. For many years, platinum has been the most valuable metal in a catalyst. There were times when it cost five times as much as palladium.
But since , the production of diesel vehicles has dropped significantly. This triggered a drop in platinum prices. In turn, precious metals used in gasoline cars have risen in price. Thus, the prices for rhodium in recent years have grown from 1. Seeing such impressive numbers, many would want to know how many of these metals are contained in one automotive catalyst? It all depends on the car, its engine, and especially the market for every model.
One car with the same engine could have different catalysts for different countries. If we calculate the "average", platinum in one catalyst is approximately one and a half grams per kilogram, palladium - 1. The knocked-out catalyst weighs about 1. The extraction of these metals from a catalyst is a rather complicated process that requires the availability of appropriate skills and various expensive substances. There are several technologies through which precious metals can be extracted.
The choice in favor of a particular technology is mainly determined by the capabilities of a person who obtains platinum from a catalyst. It is also important to understand that there are inevitable losses of recoverable materials during the refining process. In particular, such disadvantages are noted in the leaching technique, which requires multiple washing of chemical reaction components.
The surface of the catalysts is coated with precious metals. These materials can be retrieved with appropriate skills and reagents. Catalyst price depends on which sales market a particular car was originally assembled for. Higher quality catalysts are supplied to European markets than to third world countries. Average content per one ton of ceramics ppm : Pt - , Pd - , Rh - These catalysts lack palladium, but platinum is in order of ppm.
From the above, we can conclude that it is impossible to determine the cost of a catalyst without analysis! Experienced professionals know both manufacturers and even models, catalytic converters of which contain the greatest amount of precious metals.
For example, diesel cars use platinum, gasoline cars use palladium. Hybrid vehicles have higher palladium content than conventional vehicles. This is since hybrids do not have time to warm up catalyst to increase its efficiency, so more metal is required to absorb more harmful emissions. Most car owners simply sell catalysts for precious metals, rather than selling them as spare parts. The mass of palladium contained in a "honeycomb" of one catalyst can reach 1.
Considering that some premium cars use paired catalysts, the income from one car can reach a good sum of money. For example, one well-known German manufacturer contains platinum 0. The problem is that this palladium from the alloy still needs to be isolated somehow.
There are several ways and all of them are quite expensive and complicated, so there is absolutely no point in working with single instances. At the moment, the largest automakers are trying to stock up on catalyst palladium for future use, since the price for it, according to all forecasts, will only grow. But this growth cannot be endless. It will last exactly as long as it is more profitable and more efficient to use another metal - platinum.
Already, it is more than half the price of palladium. Nevertheless, the very transition of catalyst from one metal to another is not possible in a short time, the restructuring of production can take several years and many billions of euros.
That is why one of the most expensive items in the budget of many large automakers has become the search for replacements for palladium and platinum.
