ABSTRACT:
Disclosed herein is a process for producing active carbon suitable for use in electrodes for an organic solvent type electric double layer capacitor, comprising calcining an easily graphitizable organic substance and then subjecting the resultant carbonized product to an alkali activation treatment, wherein the alkali activation treatment comprises a first alkali activation treatment at a temperature within a first range and a second alkali activation treatment at a temperature within a second range, said temperature within the second range being higher than that of the first activation treatment, and one of both alkali activation treatments is performed after the other alkali activation treatment.
