The activated carbon of the present invention is characterized in that the equilibrium adsorption amount of 1,1,1-trichloroethane is 20 mg / g or more, and the pore volume of pores having a pore diameter of more than 20 Å and less than 300 Å is 0.04 cm 3 / g or more. Further, in the production method of the present invention, the phenolic resin fibers are carbonized, and then the polyolefin resin is subjected to one or more revolutions to sequentially treat the phenolic resin derivatives, and any one time revival is referred to as steam revitalization, , At least one of a calcium compound and a potassium compound is impregnated in the phenolic resin derivative until the impregnated state is maintained and the above steam activation treatment is carried out once while the impregnated state is maintained. |
