摘要： The present invention provides a raw coke having such a structure that the graphitized product resulting from graphitization of the raw coke at a temperature of 2800° C. under an inactive gas atmosphere will have ratios of the crystallite size to the lattice constant of 360 or less in the (002) plane and 1500 or less in the (110) plane, as a raw coke providing active carbon produced by alkali-activating the raw coke, which is reduced in remaining alkali content and can simplify washing operation because washing liquid can easily pass through the activated carbon, or as a raw coke for the production of needle coke.

摘要： The present invention provides a raw material carbon composition that is converted to a carbon material for an electrode in an electric double layer capacitor that can develop a high level of electrostatic capacity with good reproducibility without producing any synthetic pitch. The raw material carbon composition is converted to a carbon material for an electrode in an electric double layer capacitor upon activation treatment and is characterized in that, when the raw material carbon composition is carbonized in an inert gas atmosphere at a temperature of 1000 to 1500° C., the true relative density (RD) and the total hydrogen content (TH %) in the carbonized material obtained after the burning satisfy the following formula (1): RD=−0.75TH %+intercept  (1) wherein the intercept is 2.160 or greater.
