Patent ID: 7067051

Claim:
A process for producing a carbonized product used for producing activated carbon for an electrode of an electric double-layer capacitor, comprising the steps of subjecting a condensed polycyclic aromatic pitch having an optical anisotropic rate Oa in a range of 1%≦Oa≦90% and a softening point Ts in a range of 140° C.≦Ts≦260° C. to an oxygen crosslinking treatment at a heating temperature Th set at Th≦260° C. to provide an organic material for a carbonized product having a light component content L equal to or larger than 14.5% by weight, and subjecting the organic material to a carbonizing treatment at a temperature-raising rate Rt set at R4≦500° C./h and at a heating temperature Th set in a range 600° C.≦Th≦1,000° C. for a heating time t set at t≦2 hr.
