Activated carbons (AC) are of special interest due to their exceptional physical and chemical properties, these materials are in the form of granules or powders, but recently a new form of AC has been commercialized which is also known as Activated Carbon Fiber (ACF), and is manufactured in two presentations, cloth and felt. Activated carbon cloths (ACC) are materials that have excellent properties making them superior compared to traditional forms and are produced from precursors, through various processes that include physical and chemical activation, among the most commonly used impregnating agents are KOH, H3PO4, ZnCl2, AlCl3, NH4Cl, Na2CO3 and K2CO3, whose main function is to serve as dehydrators while preventing tars production. The characteristics and properties of the ACC depend on the nature of the material that was used to produce it, these characteristics have been used in a large number of applications, such as medicine, catalyst support systems, in the industry for the absorption of pollutants, water purification and waste water treatment, among others. This review shows the generalities and applications in recent studies and summarizes TCA applications from the different investigations carried out, as well as the process for obtaining them.

Keywords : activated carbons; activated carbon cloths; precursors; impregnants; activation.
