The characteristics of the prepared activated carbon with the yield of 19.66 % were bulk density of 0.5160 g/cm3, 6.03 % ash, iodine number of 620.16 mg/
g, methylene blue number of 176.75 mg/g and 559.48 m2/g of BET surface area. In addition, it had been found that when there was an addition of pyrolysis time with air before steam activation led to higher porosity development than one step pyrolysis and steam activation.
