I-oal based activated carbon ithuthukiswa ngochungechunge lwezinqubo ezifana ne-carbonization, ukupholisa, ukwenza kusebenze, nokugeza. Ukubukeka kwayo ngokuvamile kuyi-carbon cylindrical activated carbon, i-amorphous coal particle activated carbon, eyaziwa nangokuthi ikhabhoni echotshoziwe. I-cylindrical activated carbon, eyaziwa nangokuthi i-columnar carbon, ngokuvamile yenziwa ngezinto ezingavuthiwe eziyimpuphu nezibophezelo, ezixutshwa, zikhishwe, bese zenziwe ngekhabhoni, zicushwe, nezinye izinqubo. Ingaphinda ikhishwe kusetshenziswa ikhabhoni ecushiwe eyimpuphu kanye ne-binder. Ithuthukise ukwakheka kwe-pore, ukusebenza kahle kwe-adsorption, amandla aphezulu emishini, ukuvuselela kalula, nezindleko eziphansi; Isetshenziselwa ukuhlanzwa kwamagesi anobuthi, ukwelashwa kwegesi engcolile, ukwelashwa kokuhlanza amanzi ezimbonini nasezindlini, ukubuyiswa kwe-solvent, nezinye izici.
