What is the role of honeycomb ceramics in automobile exhaust purification?

July 31, 2024

Honeycomb Ceramics play a vital role in automobile exhaust purification and are the core carrier of three-way catalysts. Its unique structure and excellent performance enable harmful substances in automobile exhaust to be efficiently converted into harmless substances.

The role of honeycomb ceramics in automobile exhaust purification is mainly reflected in the following aspects:

1. Providing a huge surface area: The internal structure of honeycomb ceramics is similar to a honeycomb, with a large number of fine channels and pores, providing a huge surface area. This allows the catalyst to be evenly distributed on the surface of honeycomb ceramics, thereby increasing the contact area of the catalytic reaction and improving the catalytic efficiency.

2. Reduce flow resistance: The pore structure of honeycomb ceramics allows the gas to pass smoothly, reducing the flow resistance and ensuring the rapid flow and full mixing of automobile exhaust.

3. High temperature resistance and corrosion resistance: Honeycomb ceramics have excellent high temperature resistance and corrosion resistance, and can withstand the harsh working conditions of high temperature and high pressure, as well as the erosion of various corrosive substances in automobile exhaust.

4. High mechanical strength: Honeycomb ceramics have high mechanical strength and can withstand engine vibration and thermal shock, ensuring the long-term stable operation of the catalyst.

The specific working principle is as follows:

Harmful gases in automobile exhaust (such as carbon monoxide, nitrogen oxides, hydrocarbons, etc.) undergo redox reactions at high temperatures when passing through the precious metal catalyst coated on the surface of honeycomb ceramics, converting into harmless carbon dioxide, water and nitrogen. Honeycomb ceramics provide a stable carrier, ensure the activity of the catalyst, and promote the reaction.

Advantages of honeycomb ceramics in automobile exhaust purification:

1. High-efficiency purification: It can efficiently convert various harmful substances in automobile exhaust into harmless substances.

2. Long life: Excellent high temperature resistance and corrosion resistance, long service life.

3. Low pressure drop: Reduces the back pressure of the engine and improves the performance of the engine.

4. Environmental protection: Effectively reduces the pollution of automobile exhaust to the environment.

In summary, honeycomb ceramics play a vital role in automobile exhaust purification and are an indispensable part of the automobile exhaust purification system.
