MICROPOROUS CARBONS FOR FUEL GAS STORAGE

摘要

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 to 850 DEG 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 ANGSTROM . The structural and storage characteristics of the microporous carbon materials are also disclosed.
