Description Carbon molecular sieves were synthesized from indigenous bituminous coal and coconut shell. After preliminary treatment, these materials were subjected to steam or carbon dioxide activation in the range 500-900-degrees-C. In other experiments the raw materials were partly air-oxidized at approximately 200-degrees-C, mixed with binder and extruded to cylindrical pellets, which were subjected to coke deposition by cracking of methane in the range 750-780-degrees-C for 5-14 min. All the products were characterized by analysis of kinetic and equilibrium adsorption data. The molecular sieve performance was judged by the O2/N2 uptake ratio. The best carbon molecular sieves, obtained by methane cracking at 780-degrees-C at a flow of 100 ml min-1 had an uptake ratio of 2.667.
