Abstract
The very sensitive molecular-dimension criterion of adsorption selectivity of molecular sieves changes rapidly to a molecular-mass criterion upon a slight enlargement of the adsorbent-pore dimension. This resulted in the inversion of the sequence of adsorbability of hydrogen and oxygen on carbons of increasingly wider pores. Considerable care must be taken in relating molecular-sieve effects on adsorption to molecular dimensions of adsorbates.Keywords
