Honeycomb activated carbon is a new type of environmentally friendly adsorption material made from high-quality activated carbon powder as the core substrate, combined with environmentally friendly binders through mixing, extrusion molding, low-temperature drying, and high-temperature activation. It has a black, regular honeycomb structure (commonly square/rectangular) with pore sizes ranging from 1-10mm (3mm being a popular specification). Its unique honeycomb structure minimizes gas/liquid flow resistance. Combined with a specific surface area of ​​≥800m²/g and high adsorption capacity, it possesses core advantages such as high adsorption efficiency, low wind resistance, long service life, and customizability. It is particularly suitable for treating large air volumes and low concentrations of pollutants, making it a highly efficient core material for industrial waste gas purification and indoor air treatment.

Honeycomb Activated Carbon Product Details

I. Core Raw Materials and Production Process

Raw Material Composition: Selected high-iodine-value coal-based/coconut shell-based activated carbon powder (iodine adsorption value ≥800mg/g), combined with inorganic environmentally friendly binders (no secondary pollution). Some specialized products add modifiers (such as impregnation with potassium permanganate or ozone oxidation treatment) to enhance the adsorption selectivity for specific pollutants.

Refining Process: The process involves raw material mixing (activated carbon powder content ≥75%) → precise extrusion molding (mold control of pore size and dimensions) → low-temperature drying (60-80℃ to prevent cracking) → high-temperature activation (500-600℃ to activate the pore structure) → cutting and trimming (custom sizes) → inspection and packaging. The finished product has a dense structure, is not prone to powder loss, and has a pore size uniformity ≥95%.

II. Key Performance Indicators

Adsorption Performance: Iodine adsorption value 800-1200 mg/g, specific surface area 800-1200 m²/g, carbon tetrachloride adsorption rate 40-70%, benzene adsorption ≥25 mg/g, adsorption efficiency for VOCs, formaldehyde, hydrogen sulfide, etc. ≥85%. Structure and Physical Properties: Pore size 1-10mm (3mm standard size), pore density 30-100 pores/square inch, compressive strength ≥0.8MPa (longitudinal), water absorption ≤50%, ignition point ≥350℃, service life 2-4 years.

Environmental Standards: Odorless, non-corrosive, heavy metal content ≤0.001%, meets the industry standard “Honeycomb Activated Carbon for Industrial Waste Gas Purification,” and meets environmental impact assessment emission requirements.

III. Core Product Advantages

Extremely low air resistance, suitable for large air volumes: The honeycomb through-hole structure allows for smooth gas flow, with air resistance only 1/5-1/3 that of granular activated carbon. No additional fan power is required, resulting in outstanding energy efficiency. Suitable for air volumes of 1000-100000 m³/h.

High adsorption efficiency, no dead zones: After molding, the surface area utilization rate reaches over 90%, ensuring more thorough contact between pollutants and activated carbon. The adsorption rate is 20-30% faster than granular carbon, enabling rapid treatment of low-concentration (VOCs < 500 mg/m³) waste gas.

Stable structure, easy maintenance: High mechanical strength, resistant to airflow erosion and vibration, not easily broken or pulverized during use, and with a regular shape, it can be directly stacked or placed in an adsorption box, facilitating easy replacement and reducing maintenance costs.

High degree of customization: Pore diameter (1-10 mm), size (standard 100×100×100 mm, 200×100×100 mm), and adsorption characteristics (e.g., for desulfurization, for formaldehyde removal) can be customized to meet different operating conditions.

IV. Main Application Areas

Industrial Waste Gas Treatment: VOCs purification in furniture spray painting booths, automotive painting, printing, chemical, and electronics industries, as well as treatment of welding waste gas and odorous gases (hydrogen sulfide, ammonia). Suitable for pre-treatment with activated carbon adsorption boxes and zeolite rotor + CO catalytic combustion systems.

Indoor Air Treatment: Removal of formaldehyde, benzene, and TVOCs from newly renovated houses, office buildings, shopping malls, etc. Can be made into air purifier filters and fresh air system adsorption modules to quickly improve indoor air quality.

Oil Fume Purification: Adsorption of odors from cooking fumes in restaurant kitchens and food processing industries. Used in conjunction with oil fume purifiers to reduce the organic matter content in oil fumes, meeting environmental emission requirements.

Other Applications: Deep treatment of industrial wastewater (removal of organic matter and color from large-flow water bodies), deodorization of waste incineration plant exhaust gas, ammonia purification in cold storage, auxiliary materials for automotive exhaust purification, etc.

V. Specification Selection and Usage Recommendations

Specification Selection: For high-volume, low-concentration VOCs treatment, prioritize products with 3-5mm pore size and 50-80 pores/square inch; for indoor air treatment, recommend products with 1-3mm small pore size and high specific surface area; for highly corrosive gases, choose acid and alkali resistant modified products.

Usage Recommendations: Ensure gas flow rate ≤1.5m/s and contact time ≥0.8 seconds; periodically check adsorption saturation (generally, replacement/regeneration is required when the adsorption capacity reaches 20-30% of its own weight); control regeneration temperature at 300-400℃; can be reused 3-5 times.
