In today’s era of pursuing environmental protection and efficient resource utilization, activated carbon honeycomb is favored by various industries due to its unique adsorption properties.
Typically used as an optimal choice for filters, honeycomb carbon can effectively eliminate odors, particulate matter, and pollutants.
This article will delve into the concept of honeycomb activated carbon, its unique advantages, extensive application areas, and the classification of different types based on shapes.
Honeycomb activated carbon, as a special form of activated carbon, is known for its regular pore structure. It appears as a black honeycomb shape.
Honeycomb activated carbon is made from high-quality coal-based activated carbon (or coconut shell activated carbon powder) as raw material, molded through honeycomb pressing, and activated at high temperatures.
Honeycomb activated carbon can be classified into the following main types based on the final product’s shape:
Square-hole Honeycomb Activated Carbon: The honeycomb structure has regular square holes arranged neatly, suitable for applications that require uniform adsorption.
Round-hole Honeycomb Activated Carbon: The honeycomb structure consists of circular holes, making the overall structure more compact, and suitable for fields that demand relatively high pore structure.
Hexagonal Honeycomb Activated Carbon: Possesses a hexagonal honeycomb structure, providing stability while offering sufficient surface area, suitable for various adsorption and filtration applications.
Porous Honeycomb Activated Carbon: This type may contain holes of different shapes and sizes, providing diversified adsorption performance, suitable for handling complex pollutant combinations.
Different shapes of honeycomb carbon apply to different scenarios, and the choice of type depends on specific adsorption requirements and process demands.
The shaped product, using honeycomb steel molds, becomes wet honeycomb activated carbon.
After 3 days of drying, it enters the calcination furnace for 8-9 hours at a temperature of 800-900 degrees, producing water-resistant honeycomb carbon.
Honeycomb carbon has widespread applications in various fields, including chemical engineering, light industry, pharmaceuticals, environmental protection, food, and military.
It can be used as a catalyst or catalyst carrier, as well as for gas separation and purification, organic solvent recovery, gas or flue gas desulfurization, wastewater treatment, drinking water purification, decolorization, deodorization, and purification and refining.
It is suitable for treating organic waste gases (such as triphenyl and toxic gases) in factories with high airflow and low concentrations. Additionally, it is applicable for indoor air purification and restaurant oil fume treatment, as well as odor removal in appliances like air conditioners, and refrigerators.
Honeycomb activated carbon has a well-developed internal pore structure, matching the size of harmful gas molecules. It can effectively adsorb and lock formaldehyde, benzene, and other VOCs.
Efficiently adsorbs and eliminates formaldehyde, odors, smoke, dust, and bacteria.
