Properties of Activated Carbon Filters:
  • Activated carbon is the generic term used to describe a family of carbonaceous adsorbents with a highly crystalline form and extensively developed internal pore structure. A wide variety of activated carbon products is available exhibiting markedly different characteristics depending upon the raw material and activation technique used in their production. In selecting an activated carbon air filter, it is important to have a clear understanding of both the adsorptive and physical characteristics of the material in order to optimize the performance capabilities.

Adsorptive Characteristics:
  • Surface area (BET N2): Measurement, using nitrogen (N2), of the extent of the pore surface developed within the matrix of the activated carbon. Used as a primary indicator of the activity level, based on the principle that the greater the surface area, the higher the number of adsorptive sites available.

Pore size distribution:
  • Determination of the pore size distribution of an activated carbon is an extremely useful way of understanding the performance characteristics of the material.

The International Union of Pure and Applied Chemistry (IUPAC) defines the pore size distribution as:
  • Micropores r < 1 nm
  • Mesopores r 1-25 nm
  • Macropores r > 25 nm

Iodine number:
  • Measurement of the porosity of an activated carbon by adsorption of iodine from solution.

Carbon tetrachloride activity:
  • Measurement of the porosity of an activated carbon by the adsorption of saturated carbon tetrachloride vapour.

Physical Characteristics:
  • Hardness: An important factor in system design, filter life and product handling. There are large differences in the hardness of activated carbons, depending on the raw material and activity level.

Bulk Density:
  • Should be carefully considered when filling fixed volumes as it can have considerable commercial implications. The back washed and drained density will show a lower value due to the water film between the particles of activated carbon.

Particle Size Distribution:
  • The finer the particle size of an activated carbon, the better the access to the surface area and the faster the rate of adsorption kinetics. In vapor phase systems this needs to be considered against pressure drop, which will affect energy cost. Careful consideration of particle size distribution can provide significant operating benefits.  The activated carbon Multisorb 445 thank to his large surface is used in particular way to purify the air or gas at low concentration of organic solvents en it removes odours and smelts.
