What is activated carbon ?

This is the special activated carbon. It can be produced from any plant organic matter rich in carbon: wood, bark, wood pulp, coconut hulls, peanut shells, olive pits, or coal, peat, lignite, petroleum residues.

The manufacture of activated carbon is in two stages:

  • A first calcination step or carbonization (or pyrolysis), high temperature, of constituent materials.
  • A second activation step is to increase the adsorbing power, including removing tars that clog pores and in two distinct processes:
  1. Physical activation activated carbon
    Reburn Thermal Shock (900 1 000 ° C), carried out in a current of air and steam, injected under pressure (controlled oxidation process), will create millions of microscopic recesses on the surface Coal, increasing dramatically the surface and its adsorption capacity. This method gives a charcoal narrow pores.

  2. Chemical activation of activated carbon
    By phosphoric acid at 400 ° C and 500 ° C. This method gives a pore coal more larges.Le pore diameter also depends on the existing pores in the raw material used. Coconut shell and dense woods give micropores (<2 nm), white middle wood gives mesopores (2 to 50 nm) and macropores (> 50 nm) .The charcoal is produced in virtually every country in the world where there are wood resources (wood, walnut shells, bark, twigs and leaves ...).

Properties of activated carbon
The area developed by the activated carbon is enormous: a gram of activated carbon has a surface area of ​​between 400 and 2500 m². It is hydrophobe.L'adsorption gas requires pore 1 to 2 nm, while pore February to October nm sufficient for the adsorption of activated carbon powder liquides.Cette (like any charcoal) is very messy .


Sanitary applications charcoal

Decontamination of drinking water and air
Activated carbon retains a large number of organic compounds, such as pesticides. This usage is 20% of the global market:

  • Gas masks
  • Cigarette filters
  • Filters used in ventilation systems in closed circuit (eg kitchen)
  • Also used to filter the organic pollutants (particularly drug treatments) in aquariums

Chemical applications actived carbon

Activated carbon is used in many chemical applications:

  • Dechlorination of water: drinking water and other liquid food (beer, soft drinks, etc.)
  • Chlorine chlorinated oxidants (chlorine Cl2, hypochlorous acid: HClO; hypochlorite: ClO-) is reduced to chloride (Cl-) by a catalytic action

Wastewater treatment

  • Discoloration of sugar
  • Decaffeination of coffee to water
  • Hydrogen storage (activated carbon nanofibers or derivatives of coal)
  • Support for ultra divided catalytic metals, for example, activated carbon platinum, nickel on activated carbon
  • Removal of hydrocarbons in water

Use of activated carbon in the industry

  • Gold mining ores (fixation on activated carbon)
  • Hydrogen storage (activated carbon nanofibers or derivatives of coal)
  • Brushes (rubbing) in generators and motors (use of increasingly rare)
  • Supercapacitors

Use of activated carbon in medicine

  • Poisoning by absorption of toxic substances.
  • Viral or bacterial food poisoning (such as those caused by salmonella, staphylococcus, listeria ...).
  • Antidote for poisoning by drugs, narcotics, alkaloids, agricultural chemicals (organophosphorus ...), heavy metals, detergents, organic solvents. Particularly recommended in the poisoning by tricyclic antidepressants, chloroquine, paraquat, barbiturates, colchicine, phenothiazines, benzodiazepines, digitalis, salicylates, beta-blockers, meprobamate, theophylline, carbamazepine, paracetamol, etc. (these substances are then adsorbed by coal enabled which is then evacuated by natural means, carrying with him the toxin).
  • Treatment with digestive especially lowering of total cholesterol and LDL2 rates> Diarrhoea, activated charcoal is a constipating or antidiarrheal> Heartburn, aérophagies, flatulence and, with relative success, in cases of gastro enteritis, gastric pain, in the states of infection of the intestine accompanied by constipation, rumbling and intestinal fermentation, some will even use it as a poultice (mixed with water) to try to counter, just after the bite, the effects of snake venom, bee stings, bites or sometimes daraignées sea anemones.
  • We can get this activated carbon (compendial or commercial) or Charcoal Belloc in pharmacies and in organic food stores. In case of poisoning, quick medical opinion remains indispensable.Le activated charcoal has no taste, no smell, no unpleasant effect. In the absence of active peptic ulcer or intestinal obstruction, activated carbon has virtually no cons-indications, except those related to any product antidiarrheal. It is very well tolerated even at high doses. As its adsorption is rapid, it is effective from its ingestion. It should be noted, however, that taking activated charcoal is not compatible with medication, activated carbon adsorbent active molecules of these drugs. Therefore shift of 2 or 3 hours, the activated carbon outlet with other medications. However, non-activated charcoal does not interact with any concomitant medication except the pill in women. RecyclageAprès use, powdered coal is incinerated or placed in landfills. Grain, it is regenerated, with 5 to 15% of losses by treatment with steam at 900 ° C or by acid or alkaline washings

Summary of Benefits on using ACTIVATED CARBON SPECIAL Carbolite

Active micro filtration decontamination, high absorption of organic and inorganic components, significant drop chloramines (chlorine smell), purifies the water of most residual pollution, and crystal clear water, reduction of ammonium and many heavy metals, compatibility with most disinfectants, convenient packaging, recognized in its general functions very effective purification and disinfection.
