Ceramic catalytic converters

Ceramic catalytic converters
Whatever was not burnt out in the engine, on its way out will be oxidized by a ceramic catalytic converter. This reaction gives off some heat, which in turn heats up a converter up to almost 300 degrees.

Ceramic converters for afterburning solid and liquid fuels (or, as they are also called catalytic converters) are one of the most necessary elements in the exhaust systems of all modern cars.

The main task of each catalytic converter is to reduce the level of toxic waste generated during the combustion process. And these exactly converters make it possible to produce really "clean" vehicles meeting modern environmental requirements. After all, converters reduce harmful car emissions to the atmosphere by almost 90%, turning exhaust gases that contain hydrocarbons, carbon monoxide and nitrogen oxides into a practically safe mixture of water vapor, nitrogen and carbon dioxide.

Ceramic catalytic converter: design and principles of operation

What was not burnt out in the engine, on its way out is oxidized by a ceramic catalytic converter with oxygen. This reaction generates heat, which in turn heats up the ceramic converter up to almost 300 degrees. A hot catalytic converter constantly activates the oxidation process. Thus, the reaction proceeds in a circle, stopping only when the engine stops. Ceramic catalytic converters can be found in most of American and European cars. Structurally, they are carriers consisting of small ceramic honeycombs (blocks) with precious metallic sputtering target of gold, palladium, platinum or rhodium, which have brightly expressed catalytic properties. A honeycomb structure is needed in a catalytic converter in order to increase the contact area of the exhaust gas with its surface.

Catalytic converters operation

Ceramic catalytic converters a priori cost much less than metal ones. But they are very fragile - just one (and not the most powerful) bump is enough for such a converter to be broken or deformed. And there are several more reasons for the catalytic converter to get broken:

  • Low-quality gasoline (one with a lot of impurities);
  • Temperatures (most often seasonal), because of which the ceramic simply gets cracked;
  • Long operation at idle speed;
  • Bad roads (pits, potholes, poor quality of asphalt);
  • Antifreeze or oil trapped in the combustion chamber;
  • Malfunctions in the ignition system.

If the car has problems with ignition, the honeycombs of its ceramic catalytic converter will quickly be clogged and the contact area will be reduced. In this case the catalytic converter begins to oxidize exhaust gases much worse than it should.

Definitely the ceramic catalytic converter has failed in case you can observe:

  • Obvious reduction in engine power;
  • And a sharp smell of hydrogen sulfide from the exhaust pipe.

The ceramic catalytic converter resource is 100 000 km of car run. This should be taken into account, and in general it is good to monitor the condition of your catalytic converter, because the operation of the faulty one is unsafe.

Ceramic catalytic converters recycling and processing

Failed catalytic converter is a subject to immediate replacement. At the same time, the old converter, which during the operation has accumulated a huge amount of harmful combustion products, cannot just be thrown away. This brings irreparable accumulative harm to the environment. It is correct to utilize the converter - that is, to deliver the spent part to a specialized admission unit, necessarily certified for such an activity. Moreover, admission of waste converters is not free - the cost is calculated taking into account the content of precious metals deposited on each kilogram of a given carrier.

From the sorted converters first to first there will be removed the ceramic honeycombs, which then have to be ground to a homogeneous mass. Further, from the obtained homogeneous material, chemical samples will be taken for X-ray fluorescence tests. And by results of those tests experts will determine the platinoids concentration in the carrier.

Catalytic converters disposal by “Exprom” LLC

Spent or failed catalytic converters are actually the most important secondary raw material containing precious metals. That is why their processing (utilization) is beneficial:

  • For car owners who can get rid of a car part literally "stuffed" with toxic waste, without doing harm to the environment;
  • And for the utilizers who are able to legitimately extract gold, palladium, platinum and rhodium.

"Exprom"LLC is officially engaged in buying old and broken catalytic converters and is able to offer the most advantageous price for potential sellers.

The company has:

  • Large experience of successful work in the market;
  • An impeccable reputation of a reliable partner, confirmed by numerous client recommendations;
  • A broad approach to the admission of raw materials (from one single part to several tons);
  • All necessary documents for the implementation of professional operation;
  • Pickup service (experts themselves take the old catalysts from 5 kg).
