-
Honeycomb Ceramic Carrier are high-performance ceramic structures designed for catalytic, filtration, and thermal applications in extreme temperature, corrosive, or high-pressure environments. Made from advanced ceramic materials such as cordierite, alumina (Al₂O₃), or silicon carbide (SiC), they are widely used in industries including automotive, chemical processing, environmental protection, and energy. Their unique honeycomb structure provides a large surface area, excellent thermal stability, and efficient gas flow distribution, making them ideal for applications such as catalytic converters, particulate filters, and heat exchangers.
Application fields:
1. Environmental Protection and Waste Gas Treatment
• Automobile Exhaust Purification: As the core catalyst carrier for three-way catalytic converters (TWC), selective catalytic reduction (SCR) denitrification, and particulate filters (DPF/GPF).
• Industrial Waste Gas Treatment: Used as the catalyst carrier for VOCs catalytic combustion, and the efficient heat storage body in regenerative thermal oxidizers (RTO).
2. Industrial Filtration
• High-Temperature Flue Gas Treatment: Used in industries such as waste incineration and metallurgy as catalytic filters to achieve integrated dust removal and harmful gas degradation.
• Molten Metal Filtration: Used in the foundry industry to filter non-metallic impurities in aluminum, copper, iron, etc. molten liquids.
3. Chemicals and Energy
• Structured Catalytic Reactions: As the catalyst framework for key chemical reactions such as methane reforming and Fischer-Tropsch synthesis.
• Industrial Heat Storage and Energy Saving: Used as heat storage bodies in glass kilns and heating furnaces to significantly recover heat energy and improve thermal efficiency.
• Sensor Substrate: Used as the core supporting component of micro gas sensors.
