ABSTRACT:
A sulfur-containing active carbon, which has a high storage capacity for methane, is produced from inexpensive aromatic precursors, such as chrysene, coal tar and petroleum oils, tars and pitches, by reacting the aromatic precursor with elemental sulfur, followed by carbonization of the sulfur-containing reaction product in an inert atmosphere at an elevated temperature to produce a sulfur-containing carbon. The carbon is then further activated to develop a surface area of at least 600 m.sup.2 /g by heating in an oxidizing atmosphere at an elevated temperature.
