A porous @[email protected], a @[email protected] which has been subjected to reaction with gases, sometimes with the addition of chemicals, e.g. ZnCl2, before, during or after @[email protected] in order to increase its @[email protected] properties.
Activated carbons have a large @[email protected], preferably for small molecules, and are used for purification of liquids and gases. By controlling the process of @[email protected] and @[email protected], a variety of active carbons having different @[email protected] can be obtained. Activated carbons are used mainly in granular and powdered forms, but can also be produced in textile form by controlled @[email protected] and @[email protected] of textile fibres.
