Activated carbon, also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porouand thus to have a very large surface area available for adsorption or chemical reactions.
The word activated in the name is sometimes replaced with active. Due to its high degree of microporosity, just 1gram of activated carbon has a surface area in excess of 500 m2 (about one tenth the size of a football field), as determined typically by nitrogen gas adsorption. Sufficient activation for useful applications may come solely from the high surface area, though further chemical treatment often enhances the absorbing properties of the material. Activated carbon is usually derived from charcoal.
Nowadays, activated carbon is made from coconut shell, apricot shell, walnut shell, hawthorn shell, palm shell and wood charcoal in general. This production line consists of PLC automatic control system, hopper, elevator, cooling system, incinerator, boiler, blower and dust removing system.
