<p>A process for continuously manufacturing carbon molecular sieves which comprises heating a charred substrate at a minimum temperature of 482 DEG C for at least 5 minutes in a continuous manner and continuously collecting the sieves thus produced, wherein the furnace is initially brought to the desired temperature. A carbon molecular sieve, useful for separating gas or liquid mixtures containing components of at least two different molecular kinetic diameters which has the following physical characteristics: (a) an apparent density of from 0.60 to 0.70 g/cc, (b) an oxygen diffusivity (X 10<-><8>) of from 500 to 900 cm/sec<2>, (c) an oxygen/nitrogen selectivity ratio of from 6.5 to 8.5, (d) an oxygen capacity of from 4.00 to 6.00 cc/cc, and (e) an average effective pore diameter of about 4 Angstroms.</p> |
