What is Honeycomb Activated Carbon?

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.

Types of Activated Carbon Honeycomb

Types of Activated Carbon Honeycomb

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.

Manufacturing Process

70% carbon powder is uniformly mixed with 30% binder in a mixer.
The resulting pliable activated carbon mud undergoes shaping treatment with a vacuum kneading machine.
After uniform mixing, impurities are removed using a 60-100 mesh screen in the shaping machine.
The shaped product, using honeycomb steel molds, becomes wet honeycomb activated carbon.
The wet honeycomb coal is cut into precise specifications.
The cut honeycomb coal undergoes drying treatment, becoming water-resistant 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.

Applications of Honeycomb Activated 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.

Applications of Honeycomb Activated Carbon

Advantages of Activated Carbon Honeycomb

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.
