Oal based activated carbon imapangidwa kudzera munjira zingapo monga carbonization, kuzirala, kuyambitsa, ndi kuchapa. Maonekedwe ake nthawi zambiri amakhala wakuda cylindrical activated carbon, amorphous malasha tinthu activated carbon, amatchedwanso wosweka mpweya. Cylindrical activated carbon, yomwe imadziwikanso kuti columnar carbon, nthawi zambiri imapangidwa kuchokera ku zinthu zopangira ufa komanso zomangira, zomwe zimasakanizidwa, kutulutsa, kenako ndi carbonized, activated, ndi njira zina. Itha kutulutsidwanso pogwiritsa ntchito ufa wa carbon activated ndi binder. Yapanga mawonekedwe a pore, magwiridwe antchito abwino a adsorption, mphamvu zamakina apamwamba, zosavuta kukonzanso, komanso zotsika mtengo; Amagwiritsidwa ntchito poyeretsa mpweya wapoizoni, chithandizo cha gasi, mafakitale ndi zoweta zamadzi oyeretsa madzi, kuchira kosungunulira, ndi zina.
