Honeycomb Activated Carbon

Honeycomb Active Carbon is an advanced type of active carbon that has been engineered into a single unit with an orderly arrangement of parallel, open passages – a design that draws inspiration from the geometry of a natural cell. Made by pressing a mixed mix of active carbon dust and adhesive via a honeycomb mold, the resultant slab is then solidified and activated to create a solid, self-supporting structure with dense, even parallel passages throughout the whole length of the slab. The cell density is usually between 100-400 cells/sqm (cpsi), and the resulting blocks can be used in various cross section sizes and channel geometries to meet the particular system needs.

The essential difference between the cellular active carbon and the particle or column form is that the interaction between the gas and the air and the carbon surface is radically different. Instead of having liquid travel along winding, irregular paths among the dense carbon grains, the honeycomb construction provides a straight, unimpeded passage across the passages – greatly lowering the drag and also exposing the passage of the air current to the active carbon walls that surround each passage. The combination of UHP and CPAP is unique for high speed, high volume gas processing applications that would result in an unacceptable power penalty or flow limitation for conventional packaged bed systems.
