The apparent and the real micropore size distributions (PSDs) of molecular sieve carbons can be assessed by combining the adsorption of CO 2 at 273 K with immersion calorimetry into liquids of increasing molecular dimensions. On the basis of model isotherms resulting from computer simulations, the a

The preparation of unsupported and supported carbon molecular sieve membrances has been studied. It proved impossible to prepare a continuous membrane, but measurements of the mass iransfer of gases showed that diffusion across the membranes occurred both in the gas phase within large interstices an
By using model adsorbates with a convenient critical molecular diameter, no molecular sieve effect was observed with any of the microporous activated charcoal adsorbents. From the heats of adsorption measured for .the individual adsorbates, it' follows that all of the activated charcoals studied can
