ABSTRACT:
The instant invention is directed to a process for the continuous manufacturing of carbon molecular sieves having average effective pore diameters of from 2 to 15 Angstroms which comprises continuously feeding a charred naturally occurring substrate to a means for heating said substrate and heating said substrate under non-activation conditions, without the use of an externally added pore blocking substance, at a temperature range of about 900.degree. F. (482.degree. C.) to 2000.degree. F. (1093.degree. C.) for a time period of about 5 to 90 minutes.
The instant invention is also directed to a carbon molecular sieve, useful for separating gas or liquid mixtures containing components of at least two different molecular diameters, molecular weights or molecular shapes which has the following physical characteristics:
