Characteristics and Applications of Honeycomb Activated Carbon


In addition to powder and granular forms, honeycomb activated carbon represents another important product format.


I. Structural Characteristics

Honeycomb activated carbon is produced by mixing activated carbon powder with a binder and extruding the mixture through a mold to form a structured honeycomb shape. It typically comes in 100×100×100 mm blocks featuring an internal array of square through-holes.


II. Key Advantages


Low resistance: Minimal pressure drop as airflow passes through—only one-fifth to one-tenth that of granular activated carbon.


High efficiency: Large contact area between the gas and the activated carbon, resulting in rapid adsorption and desorption rates.


Ease of installation: Modular design facilitates easy replacement.


III. Application Scenarios

Honeycomb activated carbon is particularly well-suited for treating high-volume, low-concentration organic waste gas. It is widely used in:


Waste gas treatment in paint spray workshops


Solvent recovery in printing plants


VOC treatment systems in electronics and furniture manufacturing plants


In practical applications, honeycomb activated carbon is often used in conjunction with Regenerative Catalytic Oxidation (RCO) or Regenerative Thermal Oxidation (RTO) equipment to implement an adsorption-desorption-combustion treatment cycle.

 Don't underestimate that 5% moisture content. Once activated carbon gets damp, its pores become filled with water, significantly reducing its adsorption capacity. Strict moisture control before leaving the factory ensures it arrives in your hands in optimal condition.
