Abstract
A method of making activated carbon of various pore size distributions involves an providing oxidized pitch, carbonizing the pitch when the softening point of the pitch is less than about 250.degree. C., and activating the pitch to produce activated carbon. A catalyst metal can be included with the pitch to produce mesoporosity in the activated carbon.
