A method for producing an activated carbon which comprises burning waste tires containing metal cord at 700°-800° C. in the presence of oxygen and in the presence of CO 2 and water vapor and at a relative humidity of at least 60%, and recovering the activated carbon, wherein the activated carbon comprises carbon microcrystals irregularly arranged and difficulty graphitizable carbon, the difficulty graphitizable carbon comprising crosslinking lattices in the gaps among carbon microcrystals and the activated carbon having pencil hardness of from B to 6B, pore size of 100-400 Å, specific surface area of 150-500 m 2 /g, pore volume of 1.3-5.0 ml/g and CEC of 8-13. |
