Abstract of the Disclosure High surface area activated carbon fibers, wherein the carbon has a surface area of at least about 300 m2/gm (square meters per gram) are produced by heating infusible cured modified pitch fibers in air from room temperature to about 250-450°C at a rate of temperature increase of 50-200 centigrade degrees per hour, and further heating the fibers in a non-oxidizing atmosphere to about 700-900°C at a rate of temperature increase of about 50-200 centigrade degrees per hour. The surface area of the carbon in such fibers may be increased by heating the fibers in steam at about 800-900°C to produce activated carbon fibers wherein the carbon has a surface area of at least about 1000 m2/gm.
