What is car catalyst and how to classify catalytic converter?

Market of recyclable materials has a great demand for car catalysts. There is a huge number of people who want to buy a used device. The main task of such individuals is the purchase of converters at a low price, for subsequent resale in large organizations involved in processing of products on a professional basis.

Car catalyst is an additional device that is introduced into the engine to reduce toxicity. Its primary purpose is to oxidize toxic compounds contained in exhaust gases. Catalytic converter is an integral part of the exhaust system of a vehicle. It is a rather valuable and important detail.

Its general construction is simple and contain following elements:

1. A catalyst substrate, which is usually a ceramic part of a honeycomb structure.

2. A washout, which is used to disperse exhausted materials.

3. Cerium, applied in catalysis.

4. Mix of palladium and rhodium metals to realize the reaction.

Classification of a car catalytic converter includes:

• location of the part;

• materials used for manufacture;

• mechanism of interaction with fuel;

• cost and efficiency.

Various catalyst types with corresponding cost

Converters differ by catalytic layer which is actually applied. It can be of two common types:

• ceramic block made in the form of honeycombs,

• block of metal tape.

Ceramic type is more common than metal, and at the same time is characterized by its lower cost. A great disadvantage of ceramic catalysts is instability. It is quite small and weak facing the impact during the ride. Among the most common causes for destruction of ceramic catalysts is ignition system. When attempting to start the engine and fuel does not reach it immediately, the unburned quantity gets accumulated in the exhaust path destroying honeycombs.

Used catalytic converters are valued as raw materials for processing, because they contain a large amount of precious metals like platinum, rhodium or palladium. Due to the presence of heavy and radioactive metals, there are special requirements for disposal of catalytic converters. The problem of processing old catalysts is especially relevant all over the world. Buying up old or broken catalytic converters, we conclude a mutually beneficial deal for everyone, including nature.

Catalytic converter price and professional approach

Although its design is simple, the content of palladium, platinum and rhodium salts significantly affects the catalytic converter price.

Factors affecting the cost of a catalytic converter when buying:

• Type of a catalyst. Usually there are three types of catalysts (ceramic, metal and universal), a ceramic product that works with a gasoline engine is in great demand.

• Car market.

• Vehicle class.

• Car mileage, which affects the content of precious metals.

• Composition and quantity of precious metals.

• Vehicle operating conditions.

• Country of manufacture. Various countries of origin have different catalyst price, because it is about valuable components that are the object of isolation during processing.

• Year of production and intensity of operation. Catalytic converter will cost more, if it is older. New products have many structural and qualitative changes that have reduced the volume of valuable metals inside. Consider this factor, that can affect the catalytic converter cost. But it has to be presented in an inappropriate condition, without mechanical damage and significant contamination.

Catalytic converter cost

Catalysts have to be removed because of its loss of efficiency. Engine can not get enough power, or even does not start. Normal device life of the vast majority of passenger cars is 150-250 thousand km.

The procedure of purchase itself consists of several stages, which are presented below:

1. Initial inspection of catalytic converter to determine serial number and verify its compliance with established standards.

2. Preliminary weighing of the item.

3. Opening the metal housing to remove catalytic layer.

4. Product processing with a help of a special mechanism.

5. Weighing obtained powder and analysis to identify the percentage of valuable metal salts.

Searching where to hand over catalytic converters our customers receive:

• Professional individual approach.

• Worthy reward.

• Accurate determination of the number of precious metals.

• Fair price guarantee
