Honeycomb Activated Carbon

Honeycomb activated carbon is a porous, block-shaped adsorbent material prepared by mixing powdered activated carbon, binders, additives, and water, followed by extrusion molding, drying, carbonization, and activation processes.  It features regular, densely packed parallel channels (similar to a honeycomb).

Key Features

Low Pressure Drop: Parallel through-channels result in low gas resistance, with a pressure drop approximately 1/10–1/20 that of granular activated carbon, significantly saving fan energy consumption.

Allows High Gas Velocity Operation: The low pressure drop supports higher superficial gas velocities (1.0–1.5 m/s), resulting in more compact equipment and a smaller footprint.

Suitable for High-Volume, Low-Concentration Waste Gas: Ideal for treating high-volume, low-concentration VOCs, making it the preferred material for the mainstream "adsorption concentration + catalytic combustion" process.

Large Specific Surface Area and Fast Adsorption: Made from high specific surface area activated carbon, with well-developed micropores and short diffusion paths, resulting in fast adsorption and desorption rates, suitable for rapid cycle processes.

Regular Structure, Less Channeling and Dusting: The integral, regular packing ensures uniform airflow distribution, reducing channeling; virtually dust-free, preventing blockage and contamination.

Key Performance Parameters

Pore Density: A core parameter, referring to the number of pores per unit area (commonly expressed in CPI). Lower pore density means wider pores and lower pressure drop, suitable for high airflow or dust-laden exhaust gases; higher pore density means larger specific surface area and stronger adsorption capacity, suitable for clean, low-concentration exhaust gases.

Iodine Value/Carbon Tetrachloride Adsorption Rate: Reflects the degree of micropore development and adsorption capacity. Higher values indicate stronger adsorption capacity for small molecules.

Compressive Strength: Measures mechanical strength, ensuring that it is not easily broken during installation and use.

Core Application Scenarios

VOCs Treatment "Adsorption Concentration" Stage: Using the "honeycomb activated carbon adsorption + catalytic combustion/regenerative thermal oxidation" process. High-volume, low-concentration exhaust gas is adsorbed, then desorbed with a small volume of hot air to obtain a high-concentration gas, which is then sent to a subsequent oxidation device for destruction, balancing efficiency and economy.

Other Exhaust Gas Purification: Including odor treatment in sewage treatment plants and food factories; synergistic purification of pollutants such as dioxins and mercury in flue gas; air purification modules for large ventilation systems; and can also be used as a catalyst carrier to produce integrated adsorption-catalytic materials.

Summary

Honeycomb activated carbon is a core material in the "adsorption concentration + catalytic combustion" process, suitable for high-volume, low-concentration VOCs exhaust gas treatment. It achieves efficient and energy-saving treatment through adsorption concentration. For more information, please contact us via email at annayu@169chem.net or WhatsApp at +8618909016373.
