✦ Synopsis


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 be classified among the Type 1 adsorbents of the Kiselev and Yashin classification. The surfaces of such adsorbents carry neither ions nor active functional groups.

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
