Modification ofthe pore structure of microporous carbons by depositing carbon from pyrolysis of CJH6 between 973-I I23 K was investigated in regard to development of molecular sieving properties for separation of O2 and Ar. Excellent adsorption kinetics and selectivity for separation of O2 and Ar we
Abstr&-Carbon molecular sieves (CMS) and zeolites are widely used as microporous sieving solids for gas and liquid separations. However, due to hydrophobic&y, better thermal stability, and neutrality in both acidic and alkaline media, CM.% have definite advantages over zeolites. In the present work.
Exploratory runs have shown it to be possible to produce a sieve for the separation of O1 from Ar by depositing carbon from propylene in or over an activated carbon (AC) previously impregnated with Ni. It is thought that preferential cracking of propylene at the Ni sites within the pores of the AC p
