Honeycomb activated carbon dedicated to waste gas treatment is an activated carbon product with a honeycomb structure. It is made from high-quality coal-based activated carbon powder, coconut shell activated carbon powder, etc. as the main raw materials, with an appropriate amount of additives such as binders added, and undergoes processes like mixing, molding, and high-temperature activation. It appears as a black block with a flat surface and no obvious cracks. Its internal pore structure is well developed, making it an efficient waste gas purification material.
Aerodynamic Structure For High Airflow Efficiency Our honeycomb activated carbon is engineered specifically for gas-phase filtration systems where air resistance is a critical factor. Unlike traditional granular beds that impede airflow, requiring powerful fans, the straight-channel structure of our honeycomb blocks allows waste gas to pass through with minimal pressure drop. This geometric design is ideal for treating large volumes of low-concentration exhaust. The uniform holes (typically available in varying cell densities like 50, 100, or 150 cpsi) ensure that the gas stream maintains consistent contact with the carbon walls. As a professional activated carbon manufacturer, we utilize advanced extrusion and carbonization technologies to create these blocks, ensuring they maintain their shape and aerodynamic properties even under high face velocities, making them a preferred choice for modern ventilation systems.
Effective Adsorption Of VOCs and Odors The primary function of this product is to capture Volatile Organic Compounds (VOCs) and noxious odors from industrial emissions. The material matrix possesses a rich network of micropores that act as traps for organic molecules such as benzene, formaldehyde, and acetone. By providing a high geometric surface area in a compact form, the honeycomb carbon maximizes the mass transfer zone, ensuring efficient pollutant removal. This makes it an essential component for environmental compliance in manufacturing sectors. Reliability is key for activated carbon suppliers, and our product is tested to ensure it meets specific adsorption capacity benchmarks (typically measured by CTC value or Iodine number), providing facility operators with the assurance that their emissions will meet local air quality standards.
Water-Resistant Formulation For Durability Industrial exhaust streams often contain moisture or high humidity, which can be detrimental to standard activated carbon blocks. We offer a specialized water-resistant grade of activated carbon for air purification. Through the addition of durable binders and high-temperature firing, these blocks resist softening or collapsing when exposed to damp environments or steam. This structural integrity is crucial for preventing channel blockage and avoiding the disintegration of the media into the air stream. Whether installed in a rooftop scrubber or a humid painting workshop, our honeycomb blocks maintain their physical strength, ensuring a longer service life and reducing the frequency of maintenance shutdowns compared to non-waterproof alternatives.
Specific Parameters
Iodine Value: Generally ranging from 400mg/g to 800mg/g. The higher the iodine value, the stronger the adsorption capacity. For example, in some waste gas treatments with high adsorption requirements, products with an iodine value ranging from 600mg/g to 800mg/g are often selected.
Compressive Strength: The normal compressive strength is greater than 0.8MPa, ensuring that it is not easily broken during use and can withstand certain pressures and air flow impacts.
Specification Sizes: Commonly available in sizes such as 50×50×100mm, 100×100×100mm, etc. It can also be customized according to users' needs, such as 100×100×50mm.
Pore Density: Usually 100 pores per square inch, 150 pores per square inch, etc. Pore density affects the contact area between gas and activated carbon as well as the adsorption efficiency.
Operating Temperature: Generally, the operating temperature is less than 400 degrees Celsius. If it exceeds this temperature, the adsorption performance may be affected.
Empty Tower Wind Speed: The empty tower wind speed is generally around 0.8 meters per second. At this wind speed, good adsorption effect and low air resistance can be ensured.
Specific Surface Area: The specific surface area is greater than 700 square meters per gram. A larger specific surface area provides more adsorption sites and enhances the adsorption capacity.
Applications
Industrial Waste Gas Treatment: Widely used in waste gas treatment in industries such as chemical engineering, pharmaceuticals, electronics, spray painting, and smelting. It can effectively remove various organic waste gases and acidic and alkaline gases such as benzene, toluene, xylene, acetone, ethanol, ethyl acetate, hydrogen sulfide, phosgene, and malodorous gases, reducing the pollution caused by waste gas emissions to the environment.
Air Purification: Used for indoor air purification to remove harmful gases such as formaldehyde, benzene, and TVOC in the air, improving air quality. It is suitable for newly decorated houses, offices, and public places.
Solvent Recovery: In industries such as pharmaceuticals, printing, and chemical engineering, it can recover volatile organic solvents such as toluene, xylene, and ethanol during the production process, realizing resource recovery and utilization, reducing enterprise costs and environmental pollution.
Use Scenarios Semiconductor And Electronics Fabrication Plants In the semiconductor industry, maintaining air purity in cleanrooms is critical for wafer yield rates. Facility managers face the threat of Airborne Molecular Contaminants (AMCs), specifically VOCs like Isopropyl Alcohol (IPA) and Acetone used in cleaning processes. Our activated carbon for air purification is installed in the Fan Filter Units (FFUs) or Makeup Air Units (MAUs) within the "Fab." The straight-channel honeycomb design allows for laminar airflow, which is essential for maintaining cleanroom turbulence standards. Unlike granular beds that might shed dust (particulates) harmful to microchips, our high-strength honeycomb blocks provide a clean, stable adsorption solution. This application highlights our role as specialized activated carbon suppliers capable of meeting the stringent purity and pressure specifications required by high-tech electronics manufacturers. Industrial Printing And Flexible Packaging Operations Rotogravure and flexographic printing facilities emit significant amounts of organic solvents such as ethyl acetate and toluene during the drying process. A plant compliance officer utilizes our honeycomb activated carbon to manage these emissions strictly under national environmental limits. Given the massive airflow required to dry the ink quickly, a high-resistance filter would bottleneck production speed. Our honeycomb carbon offering allows for high superficial gas velocities (often 0.8–1.2 m/s) without creating backpressure that affects the drying ovens. The water-resistant grade is frequently selected here to withstand the humidity variations in the workshop. This ensures continuous compliance and protects the factory from regulatory fines, demonstrating the operational value of selecting robust honeycomb carbon for heavy industrial manufacturing.
Advantages
High Adsorption Efficiency: The honeycomb structure enables a large contact area and long contact time between gas and activated carbon, allowing it to fully adsorb pollutants in waste gas. The adsorption efficiency can reach around 67.16% - 80%. Compared with traditional granular activated carbon, it has obvious advantages in treating low-concentration and large-air-volume organic waste gases.
Low Air Resistance: At a wind speed of 2 meters per second, the air resistance is less than 80 Pa. The resistance when gas passes through is small, which can reduce the energy consumption of equipment and cut down operating costs.
