Abstract
A method of making a microporous carbon material which includes providing a precursor selected from the group consisting of crystalline salts of aromatic sulfonates and nonporous polymeric salts. Heat treatment of such precursors in the temperature range of 350.degree. to 850.degree. C. in an inert oxygen free atmosphere for a sufficient time promotes thermally induced hydrogen abstraction and rearrangement of BSUs which result in the formation of a carbonaceous microporous material having a pore size distribution in the range of about 4-15 .ANG.. The structural and storage characteristics of the microporous carbon materials are also disclosed.
