Oil palm shell, a solid waste of palm oil industry in Malaysia was used as a raw material for the production of micro-and mesoporous activated carbons.The chemical activation process with different impregnating agents (60 % zinc chloride, 85 % phosphoric acid and 85 % potassium hydroxide) was conducted at various temperatures, under the purified nitrogen and carbon dioxide condition.The physical characteristics of activated carbon were estimated from nitrogen adsorption-desorption isotherm data at 77 K and on the relative pressure range of 0.005-0.99.The highest BET surface areas of the activated carbons were 1367 m2 g-1, 1917 m2 g-1 and 2205 m2 g-1 obtained from 60 % zinc chloride,85 % phosphoric acid and 85 % potassium hydroxide impregnation, respectively.
