In the modern cars there are a lot of interesting things. It turns out that there are even noble metals in it and the car owner himself can make good money with its help.
Not everyone knows that the so-called exhaust system catalyst or rather, an exhaust gas catalyst contains precious metals of the platinum group. First of all, it is actually platinum, as well as noble metals palladium and rhodium.
A porous ceramic or metal filling is hidden in catalyst housing, where another noble metal is spraye.
Therefore
after the automotive converters unlimited fails and this usually happens after 150-200 thous and kilometers, you can take it to special processing companies, which are able to extract precious metal for recycling.
The main nuance of this procedure is that platinum metals are in a form of a very thin layer spraye onto porous ceramic cells.
In fact, the device is conceive as such, so that the contact surface of exhaust gases with metal converters unlimited is as wide as possible. Therefore, collecting spraye platinum from 20 thousand square meters of the inner surface of the honeycomb is not so simple. To do this, it is necessary to “rinse” catalyst ceramics with acids, heat, galvanize, crush… But this, in fact, is a problem not of a motorist, but of other people.
How to determine the profit which aconverters unlimited can bring to a driver owing to this? To determine the number of platinoids, an RF spectrometer is used, it is also an X-ray fluorescence analyzer.
But first of all, you need to see the catalyst case, pull out the ceramic filler and grind it. Then, correlating the data of spectrometer and mass of ground filling, the receiver determines the price.
The average price of a converters unlimited that has worked out is from 20 to 150 USD, and you can get them just passing an unnecessary catalyst at the pick-up point.
It is interesting that evaluators take into account the current quotations on world exchanges when evaluating. And this figure relative to platinum can experience significant fluctuations,
for example:
depending on the situation, one ounce in different periods can cost several hundred dollars and one and a half thousand dollars.
The content of precious metals in a converters unlimited is determine using a spectrometer. Incidentally, it is able to distinguish platinum substitute.
To understand: the content of pure platinum or other platinoids is tenths and hundredths of a percent of the total mass of converters unlimited filling.
Taking into account how much a new converters unlimited costs, which will have to be bought to replace a faile one, handing over the old for recycling will be the most rational step. And even if you don’t want to buy a new converters unlimited and intend to replace it with a substitute, you should still think about recycling. The price is worth the time spent on the delivery of precious recycle materials.
The platinum content in Japanese and Chinese cars is 15% less than in Europe, in catalysts of Russian cars 40% less than rhodium in Europe. In American catalysts, precious metals are half as much as in European ones.
To solve the problems of processing converters unlimited , hydrometallurgical and pyrometallurgical methods are used. The source for processing contains a large amount of ceramic carrier and an insignificant concentration of precious metals. When processing waste electronics, the source is scrap parts that contain, as a rule, plastic particles in their composition.
