  • 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 is used to treat poisonings and overdoses following oral ingestion. It prevents absorption of the poison by the gastrointestinal tract. Activated carbon has become the treatment of choice for many poisonings, and other decontamination methods such as ipecac induced emesis or stomach pumps are now used rarely.
  • 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.
  • Potable water currently is the largest end-use market for activated carbon, accounting for 101 million pounds or 37 percent of total consumption of liquid-phase applications in 2002. Demand for activated carbon in public service water is expected to grow at approximately 4.5 percent annually.
  • In 2002, gas-phase applications of activated carbon accounted for 75 million pounds or 21 percent of total activated carbon consumed in the United States. 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 through 2006.
  • Activated carbon is expected to grow in the U.S. at approximately 3 percent annually over the forecasted period to 2006, mostly driven by environmental considerations. Large underutilized capacity overseas will provide a ready supply of potential imports which will tend to limit price increases for most grades.
  • US activated carbon demand will rise 4.3 percent annually through 2008 based on growing requirements for motor vehicle emission canisters and greater use in industrial mercury removal.
