Abstract

Activated carbons have been prepared by physical activation with H₂O-CO₂ in two-step pre-treatment including ZnCl₂-HCl from acorn shell at 850°C. The active carbons were characterized by N₂ adsorption at 77K. Adsorption capacity was demonstrated by the iodine numbers. The surface chemical characteristics of activated carbons were determined by FTIR spectroscopic method. The microstructure of the activated carbons prepared was examined by scanning electron microscopy. The maximum BET surface area of the obtained activated carbon was found to be around 1779m²/g.
