Quite often, we encounter a situation in which we accept delivery of a monolith from new contractors and it is separated due to where it was cut from. We get then: separately monolith from gasoline vehicles, separately from diesel engine and from DPF filters. When we ask where the idea comes from, it turns out that the clients cooperating with other buyers earlier, received instructions to divide and deliver the material in separate parts. That is why they got used to this method and the belief that this is the only right solution.

It turns out, however, that this is not the best and most profitable idea. We are in a hurry to explain.

Packing the entire monolith together is a much simpler and more economical solution. It is not only saving time, work, but also money.

If you provide us with a monolith in one batch, we make it one-time, mark it, weigh it, thoroughly ground and analyze. When the monolith is separated, the same operations are performed in several approaches, which makes the time of obtaining the final information unnecessarily longer. It is therefore associated with higher work expenses, and thus – higher costs. Consequently – you receive less money compared to the same material, included in one whole.

So where did the idea for separating the monolith come from?

This method is used by purchase stores that do not have adequate equipment to allow efficient analysis of such a diversified material. In order to determine the content of precious metals in a mixed monolith, it is necessary to use high-class devices, such as weight and moisture analyzer (a device allowing simultaneous determination of moisture content and sample weight), and above all professional spectrometers. Relevant are also suitable ball mills and homing devices which will lead the monolith to homogenised form. Here the rule is simple – the more finely ground monolith, the greater the precision of the measurement and the more you gain from the transaction.

How much to bring to buying?

The delivery of a larger batch of monolith is definitely more profitable. The bigger, the more favorable you go out. Of course, as we have already mentioned, we start with a 100-pound monolith delivery at our headquarters. It is much more profitable, however, to “pick up” and deliver a batch weighing over 300 kg. With such a large amount we make so-called “Double check” or double check of the result. In addition to XRF analysis, we also carry out chemical analysis with the help of an advanced ICP MS device, which is considered more accurate. And at the same time we have confirmation of the result by obtaining it from two independent devices.

And what about precious metal courses?

Many of our customers decide to bring us the minimum possible amount of monolith, because precious metal rates are beneficial at the moment. They do not want to wait with more delivery, for fear of a possible fall in quotations. However, we are able to provide companies with whom we cooperate with a sense of security and “set up” exchange rates on the day of valuation for a period of 30 days. Thanks to this, they can easily wait and appear in our company with a larger party, which is certainly more profitable.

How do you choose the best monolith purchase?

As you can see, paradoxically, not only the content of precious metals in the supplied monolith determines how much you will earn from selling it. It is also very important to choose the appropriate collection point, which is the point that:

• it has new high-class equipment – it is worth paying attention to whether the purchase uses high-quality scales, moisture meters, ball mills, mixing devices, and spectrometers that have been authorized by the National Atomic Energy Agency;
• has qualified and experienced staff, and there is no employee rotation in the company. Then you can be sure that the equipment supports non-random people who know the whole process perfectly;
• explains in a clear and accessible way how the analysis and valuation process proceeds. Everything takes place in an open manner and the client has the right to be present at every stage;
• gives a price guarantee – regardless of fluctuations in the quotations, you have the opportunity to “fix” the course for a period of 30 days;
• performs the appraisal, preparing the monolith for analysis and the very analysis on the spot, without intermediaries – it also saves time and money;

DS AUTO guarantees all the above benefits and we can also offer our own transport. The one-time delivery is up to 24 tons.

Artykuł How to earn the most on a monolith? pochodzi z serwisu Katalizatory Chrzanów.

Automotive concerns were aware that it was necessary to reduce their number. Initially, technical means were used for this purpose, whose operation was regulated by legal norms. One of the solutions used was the afterburning process. Thermal reactors have been located behind the outlet valves in which oxidation of hydrocarbons and carbon oxides took place.

In later years, the ecological awareness of people gradually increased. It began to be noticed that the solutions used were not sufficient. Therefore, catalysts have been introduced.

Catalysts have a very important function in the exhaust system. Their task is to clean car exhausts from toxic substances such as carbon oxides, nitrogen oxides and hydrocarbons.

In order to be able to carry out this task, precious metals contained in them are necessary – platinum, palladium and rhodium. It is they who perform the correct catalytic function. Due to their presence, the chemical composition of the exhaust gases that escape from the combustion chamber differs from those that escape from the exhaust pipe.

How are they built?

Catalysts consist of the following layers:

A metal casing, which is the first, outer layer; mesh / lagging, whose task is to protect the monolith; and the ceramic monolith itself.

The cross-section of the catalyst can be illustrated on the example of the Fiat model.

Operation of catalysts

Harmful combustion products are reacted by the oxygen present in the exhaust. This creates pure nitrogen, water vapor and carbon dioxide, which is less dangerous than its oxide. Oxidation depends to a large extent on the appropriate temperature. The time, which is available for natural oxidation, without any external support is extremely short. Not all toxins will burn.

That is why it is necessary to mount catalysts. Their role is to guarantee conditions that will increase the intensity of reactions neutralizing toxic substances.

There are two types of reactions resulting in the purification of exhaust gases: oxidation and reduction reactions. As a result of oxidation, hydrocarbons and oxides of carbon react with oxygen, thanks to which we get CO2 and water vapor. On reduction, nitrogen and carbon oxides enter a reaction that produces nitrogen and carbon dioxide.

Types of catalysts

There are basically two main types of catalysts on the market – metal and ceramic catalysts. The latter are much more common.

The metal catalyst is made of extremely thin, metal tape, made of heat-resistant, chromium-nickel steel. Aluminum admixtures are also used in their production. The tape is covered with a corrugated ribbon containing a layer of precious metals. In the production of 1 catalyst, about 1.5 g of the alloy is used.

Benefits:

+ faster temperature reaching appropriate for the cleaning process

+ high mechanical strength

+ resistance to large temperature changes

+ longer life of parts

+ lower flow resistance

Disadvantages :

– higher price

It is for this reason that these catalysts are assembled less often and usually in more expensive cars than catalysts with a ceramic insert.

Catalysts with a ceramic insert, in turn, are built of block ceramic core – so-called monolith. It has a structure resembling a honeycomb. This structure is formed by channels covered with noble elements.

It is worth emphasizing here that the purification requires not only gas combustion products, but also produced solid particles. A big problem with self-ignition engines is the soot particles that are dangerous to our health. In this case, you do not need chemical and mechanical filtration. Solid settle on porous fibers, thanks to which they can be “burned” in it.

Due to the way they work, they are susceptible to clogging, and thus require frequent regeneration or – if it is impossible – replacement.

Very often it is possible to find combined devices in which the particulate filter is mounted together with the catalyst. This allows simultaneous purification of gas fumes and solid contaminants.

At DS AUTO we buy not only complete catalysts. We also accept the insert itself (metal or ceramic), and a monolith in any form – whole, in pieces or in powder.

Regardless of the character, thanks to the fact that we have experienced staff, professional machine park and our own laboratory, we are able to make a precise analysis of the precious metal content in the delivered material, properly priced and processed.

It is also our responsibility to properly prepare the monolith for testing. Weigh and describe, grind in ball mills and bring to a uniform, homogenized form and take a sample for testing.

The test is carried out using spectrometers. In our everyday work, we use the ICP MS device and Olympus spectrometers.

As you can see, in the case of purchase of the metal cartridge itself, ceramic monolith in pieces, powder or DPF filters, recognition and valuation require appropriate equipment as well as specialist knowledge and experience.

The following figure shows the annual sum of collected catalysts.

As you can see, the Małopolskie voivodship was ranked first with the DS Auto capital group, which includes the largest catalyst converter in Poland – Unimetal Recycling Sp. z o.o.

The amount we have collected is impressive and amounts to 384,000 catalysts code 16 08 01 and 16 08 03. The second place was taken by companies from the Wielkopolskie voivodship with the number of 46 thousand, followed by the Mazowieckie voivodship, in which the purchases recorded the value of 33,000. pieces.

Noteworthy is the Lubuskie Voivodeship, in which the number is less than 29 thousand used devices.

Where did we get the good result we achieved?

In spite of the less favorable location than in the case of voivodships with a larger number of inhabitants, such as Mazowieckie, Śląskie or Wielkopolskie, we found ourselves in the first place in the ranking.

Our position and the number of catalysts that we buy and recycle primarily results from the fact that as the only company dealing with it, we have such an extensive network of partner collection points throughout the country. These points deal with retail quantities, while we accept wholesale deliveries from the largest dismantling stations in Poland.

All points with which we have the pleasure to work are trustworthy stores that enjoy a good reputation among the sellers. We are aware of how much we can do together and how much this cooperation is building up for everyone. When we hear flattering opinions that thanks to us someone’s company has developed and is successful using our solutions, we know that all this makes a huge sense, and our persistent work is not in vain.

In addition, we use the best valuation tool – CatCatalog‘s largest online catalyst database, with over 7,700 models. Thanks to this tool, collection points that want to develop and operate professionally, can implement this plan. Without such support, they would have to equip themselves with expensive equipment to analyze the precious metal content and analyze all the models they want to adopt. We did this work for them.

What distinguishes us on the market is also our own laboratory. Thanks to it, our offer is complete and contractors avoid participation of agents in the whole process. We can therefore offer you the best possible prices. The analysis takes place on site, and in addition it is public, so anyone who would like to cooperate with us can observe how we work. We have no secrets for you.

The strength of the laboratory lies not only in the technology used – certified spectrometers that indicate the real content of precious metals in the material. Its reputation is primarily determined by the people who create it. They are the best qualified specialists with vast knowledge and practical experience. Having expensive and good equipment will not be a success in itself. It will definitely help, but it is not enough. The most important are people who have the right skills and knowledge to use it. The laboratory is equipped with certified stationary spectrometers such as ICP MS, which is undoubtedly the best position on the market at the moment, and portable spectrometers of the recommendable Olympus brand.

What we can offer as one of the few companies is the transport of waste. At one time it can be up to 24 tons. If you are planning such a large delivery, we encourage you to contact us. We have all the required permits, both for the needs of transport and for the collection or processing of waste with the codes 16 08 01 and 16 08 03. We can therefore cooperate in the purchase of all types of catalysts on the market.

It is also worth mentioning the modern hall, equipped with a reliable machine park, which consists of machines for cutting catalysts and monolith recovery and precise ball mills that grind the monolith, to obtain a granular material with appropriate granulation, which is transferred to the laboratory. Good equipment and experienced professionals are the best possible combination.

The last – possibly the most important – reason for our place in the ranking is the satisfaction of people with whom we work and whom we have never let down. It is thanks to the trust you give us that we have achieved so much.

Thank you to everyone for cooperation in 2018. We do everything to make this year equally fruitful.

Contact us to cooperate with us!
