ADSORPTIVE CAPACITY FOR VAPOR CONTAMINANTS
In general, vapor contaminants can be indexed in terms of how well they are adsorbed by activated carbon. This, typically, is a function of the carbon's affinity for a specific type oforganic or inorganic contaminant, such as ketones, apilhatics, and sulfur compounds.
Additionally, the adsorptive capacity and removal efficiency may be affected by:

  • The concentration of the contaminant (s).

  • Humidity o the air or gas stream.

  • Temperature of the vapor laden air stream.

  • Contact time between the activated carbon and vapor laden air.

  • Particle size of activated carbon.

  • Grade of activated carbon.

  • Sufficient for Most applications.

Category

Rating

Adsorptive Capacity and Weight Capacity, %

Average

1 High 20 to 50% 35
2 Good 10 to 20% 16
3 Moderate Less than 15% 8
4 Low Usually too low to be effective**  

**Impregnated carbon may be required if applicable. Some of the contaminants listed in the table are specific chemical compounds.
Some represents classes of compounds and others are mixtures and of variable
compositions. Activated charcoal capacity for odors varies somewhat with the
concentration in air with humidity and temperature. The number given represents
typical or average conditions and might vary in specific instances.
