Adsorbent Purification and Separations
Activated carbons are carbonaceous adsorbents with a highly crystalline form and high internal pore structure. A wide variety of activated carbon products are available depending upon the starting raw material and activation technique. Activated carbons are used to recover organic solvents, purify CO2 from fermentation processes, purification of drinking water, amine and glycol treating. decolorizing of water, and various other chemical and petrochemical processes. Activated carbon has an incredibly large surface area per unit volume at over 900 m2/g and a network of submicroscopic pores.
Micropore region - less than 100 Angstroms
Mesopore region - between 100 and 1,000 Angstroms
Macropore region - greater than 1,000 Angstroms
A broad range of pore sizes is available for both gases and liquids
