Why do honeycomb ceramics appear in internal combustion engine reprocessing systems?https://www.chempackings.com/honeycomb-ceramic/
Honeycomb ceramics is a kind of ceramic material with high porosity. High specific surface area and good oxidation stability. Its unique physical and chemical properties. Which make honeycomb ceramics also used in internal combustion engine after-treatment system.
Combustion engines produce a lot of harmful gases, such as carbon monoxide, nitrogen oxides and volatile organic compounds. when burning fuel. These harmful gases are harmful to the environment and human health. In order to reduce the emissions of these harmful gases. Internal combustion engines need to install post-treatment systems to convert harmful gases into harmless gases or reduce their emissions.
Honeycomb ceramics are mainly used in catalytic converters of exhaust gas treatment systems of internal combustion engines. A catalytic converter is a device used to transform harmful gases, consisting of a catalyst and a carrier.
01 Honeycomb ceramics as a carrier in the catalytic converter advantages:
1 High specific surface area: Honeycomb ceramics have high porosity and high specific surface area, which can provide more reactive active sites and improve the catalytic conversion efficiency.
2 Good oxidation stability: honeycomb ceramics have good oxidation stability and high temperature stability, can work stably at high temperatures, will not lose catalytic activity because of the combustion reaction.
3 Good plasticity: honeycomb ceramics have good plasticity and machinability, can be designed and processed according to needs, to adapt to different working conditions and catalytic conversion requirements.
Honeycomb ceramic is used as a filter material in the particle trap advantages:
- Efficient capture: honeycomb ceramic filter material has a porous structure. which can filter out fine particulate matter in the emission, so as to achieve the purpose of efficient capture. Its capture efficiency can be as high as 95%.
- Strong durability: honeycomb ceramic filter material is made of high-strength materials, with high heat resistance and corrosion resistance. It can be long-term stable operation in high temperature, high pressure and other harsh environments, strong durability.
- Easy maintenance: Honeycomb ceramic filters can be cleaned or sintered regularly to remove the particulate matter that accumulates in the filter. Thereby maintaining its capture efficiency and durability. Honeycomb ceramic filters after cleaning or sintering can be reused to save costs.
- Small size, light weight: compared with other filter materials, honeycomb ceramic filter material thickness is thin, occupy small space, light weight, easy to install and replace.
