A B S T R A C T The instant invention is directed to a molecu- lar sieve comprising a carbonaceous substrate selected from the group consisting of molecular sieve carbon, calcined coconut char, oxidized and devolatilized agglomerated coal, calcined agglomerated coal and cal- cined agglomerated coconut char, impregnated with an organic polymer having a molecular weight of at least 400, as determined by vapor phase osmometry, or with an inorganic polymer at a dosage of at least 0.001 weight percent (based on the substrate weight) up to a maximum dosage which still allows the resulting sieve to sepa- rate gas or liquid mixtures containing components of at least two different molecular diameters, molecular weights or molecular shapes. The instant invention is also directed to a process for preparing the molecular sieve and to a process for using it to separate gas or liquid mixtures.
