The tape produced on the PZPS is used in exhaust gas neutralizers

Diesel engine exhaust gases contain many harmful substances, including benzpyrene, a hydrocarbon formed during the incomplete combustion of organic compounds, is particularly dangerous. It is one of the most common and dangerous carcinogens.

To combat such pollutants, various exhaust gas purification technologies are being developed, among which catalysts play a key role. In this article, we will look at the role of Fechral alloy tape made of PZPS in modern exhaust gas converters.

Harmful substances in diesel engine exhaust gases

Exhaust gases from diesel cars contain many harmful substances, including hydrocarbons, nitrogen oxides (NO)_x), carbon monoxide (CO), and particulate matter. Benzpyrene, which is formed as a result of incomplete combustion of hydrocarbons, is a particular health hazard. The main reasons for its occurrence include:

• the wrong ratio of air and fuel in the combustion chamber;
• insufficient fuel combustion temperature;
• poor fuel quality.

The release of benzpyrene during fuel combustion is dangerous for the environment and human health. It accumulates in soil, water and air, and enters the human body through the respiratory tract and skin. In high concentrations, benzpyrene can cause serious illnesses.

Catalysts for purifying exhaust gases and reducing benzpyrene emissions

To reduce emissions of benzpyrene and other harmful substances, it is necessary to ensure complete combustion of fuel and control its quality. Exhaust gas converters play an important role in this process. Platinum-based catalysts contribute to the complete oxidation of harmful substances to carbon dioxide and water. The principle of their work is as follows:

1. Exhaust gases enter the catalyst.
2. Inside the catalyst, gases pass through a layer containing platinum.
3. Platinum accelerates chemical reactions, turning harmful substances into less hazardous compounds.
4. The purified exhaust gases leave the catalyst and enter the atmosphere.

It is especially important to use catalysts when conducting both open and closed mining operations, since in mining conditions, the accumulation of harmful substances is especially dangerous for human life and health.

In addition to catalysts, there are other technologies for cleaning exhaust gases, including particulate filters and exhaust gas recirculation (EGR) systems. However, platinum-based catalysts remain one of the most effective means of cleaning exhaust gases and are widely used in modern diesel engines.

Fehral as a material for catalysts

Fehral, high electric alloy resistance and increased heat resistance, is the optimal material for creating diesel engine filters. Fechral tapes produced at PZPS are widely used in exhaust gas catalysts. The main fechral brands used for this purpose are X15YU5, X23U5, X23YU5T.

The advantages of using fechral:

1. Heat resistance — the ability to withstand high temperatures, reaching several hundred degrees Celsius, makes fehral an ideal material for the operating conditions of diesel engines.
2. High electrical resistance — makes it possible to use fechral to heat exhaust gases, which contributes to the efficient operation of the catalytic converter.
3. Strength and durability — fecral is highly durable and resistant to corrosion, which ensures the durability of the filters.
4. Compatible with catalysts — fecral does not react with catalyst components, such as platinum or palladium, which allows them to effectively interact with them to purify exhaust gases.
5. Economic efficiency — the use of fechral is cost-effective due to its availability and excellent performance characteristics.

Using fechral for tape productionused in exhaust gas catalysts, is an important step towards reducing harmful emissions from diesel engines. Due to its unique properties, fechral ensures the effective and durable operation of catalytic converters, helping to protect the environment and human health. In modern conditions, where environmental safety is a priority, such technologies and materials play a key role in developing and improving exhaust gas treatment systems.
