A method for preparing active carbon, which comprises: (a) a pulverization step of pulverizing a non-caking coal or a coal composition comprising a non-caking coal and a caking coal whose content in the coal composition is not higher than 40 % by weight to pulverized particles having an average particle size of not larger than 10 mu m; (b) a granulation step of granulating the resulting pulverized particles to granules; (c) a carbonization step of carbonizing the resulting granules; and (d) an activation step of activating the resulting carbonized granules. |
