Oal based activated carbon e etsoa ka letoto la lits'ebetso tse kang carbonization, cooling, activation, le ho hlatsoa. Ponahalo ea eona ka kakaretso ke khabone e ntšo ea cylindrical activated, amorphous coal particle activated carbon, eo hape e tsejoang e le k'habone e sithabetseng. Cylindrical activated carbon, eo hape e tsejoang e le columnar carbon, hangata e entsoe ka thepa e tala e entsoeng ka phofo le li-binders, tse kopantsoeng, tse ntšitsoeng, ebe li etsoa ka carbon, activated, le mekhoa e meng. E ka boela ea fetisoa ka ho sebelisa carbon activated powder le binder. E ntlafalitse sebopeho sa pore, ts'ebetso e ntle ea adsorption, matla a phahameng a mochini, ho nchafatsoa habonolo, le litšenyehelo tse tlase; E sebelisoa bakeng sa tlhoekiso ea likhase tse chefo, kalafo ea khase e litšila, kalafo ea tlhoekiso ea metsi ea liindasteri le malapeng, ho hlaphoheloa ha solvent, le lintlha tse ling.
