The activated carbon was prepared from different palm biomass sources i.e.empty fruit bunch, palm fibre and palm kernel shell using pyrolysis followed by physical activation in a quartz tube furnace. The bio-chars that obtained from pyrolysis with higher carbon content were selected for the preparation of activated carbon. These bio-chars were physically activated by carbon dioxideflow at different heating rate, activation temperature and activation time in order to improve their properties. The activation of bio-char was prepared at 400-900°C for 0.5-2.0 hr with heating rate of 5-20°C/min in quartz tube furnace. The results revealed that the physical properties i. e. BET surface area, total pore volume and average pore diameter is 700-1000 m2/g, 0.30.5cm3/g and 2.0-2.5 nm, respectively, indicated that the activated carbon can be used as high grade adsorbent in water treatment, gas purification, dye removal and substitute carbon black as filler in tires manufacturing instead of using conventional activated carbon which is more expensive carbon precursor from coal and charcoal.
