- Activated carbon, also
called activated charcoal or activated coal, is a general term which
covers carbon material mostly derived from charcoal. For all three
variations of the name, "activated" is sometimes substituted with
"active".
- It is a material with
an exceptionally high surface area. Just one gram of activated carbon
has the surface area of approximately 500 m2, typically determined by
nitrogen gas adsorption, and includes a large amount of microporosity.
- It can be produced in
two different processes from a variety of carbonaceous source materials,
e.g. nutshells, wood, coal. It can be produced using Physical
reactivation and chemical activation processes.
- Adsorption on granular
activated carbon finds growing use as an effective and economical
process for purifying liquids by separating low concentrations of
absorbable molecules from liquids. Examples of some large volume
applications of this process are the de- colorization of sugar
solutions, removal of taste and odor from potable water, and the removal
of dissolved organics from industrial and municipal waste
streams.
- Activated carbon does
not bind well to certain chemicals, including lithium, alcohols,
glycols, ammonia, strong acids and bases, metals and most inorganic
minerals, such as sodium, iron, lead, arsenic, fluorine, and boric acid.
Activated carbon does adsorb iodine very well and in fact the iodine
number, mg/g, (ASTM D28 Standard Method test) is used as an indication
of total surface area.
- Activated carbon can be
used as a substrate for the application of various chemicals to improve
the adsorptive capacity for some inorganic (and problematic organic)
compounds such as hydrogen sulphide (H2S), ammonia (NH3), formaldehyde
(HCOH), radio-isotopes (Iodine-131) and mercury (Hg). This property is
known as chemisorption.
Activated carbon
filters can be used to filter vodka of organic impurities. Since the
activated carbon does not bind well to alcohols, the percentage of
ethanol is not significantly affected, but the carbon will bind to and
remove many organic impurities which can affect color, taste, and
odor.
- End-use
applications such as solvent recovery and air purification are
benefiting from stricter environmental regulations (such as the Clean
Air Act Amendments of 1990) and increased indoor air quality issues in
both residential and commercial environments. Activated carbon use in
automotive emission canisters is also benefiting from environmental
legislation. Overall, total consumption of activated carbon in gas-phase
applications should grow at an average annual rate of 3.5 percent
