Summary A Saran carbon has been treated with carbon disulphide and sulphur in order to introduce sulphur surface complexes, a commercial activated carbon was also used. Samples obtained were characterized by their surface areas and porosities. The adsorption of n-hexane, benzene and cyclohexane has been measured out at high temperatures and under dynamic conditions using a gas chromatographic technique. Results were compared with those obtained when oxygen-surface complexes were introduced and it can be concluded that when CS2 is used with a highly microporous carbon, such as Saran, a molecular sieve for cyclohexane (mean size 0.58 nm) is produced at determined amounts of sulphur fixed.
