PHYSICAL ADSORPTION OF GASES BY MICROPOROUS CARBONS

A summary of some of the fundamental work, on physical adsorption of gases by microporous carbons, carried out by the authors at Brunel University is presented. The development of the alpha(s), Dubinin-Radushkevich and n-nonane preadsorption methods for the characterisation of micropore structure, and the evidence for the primary and secondary processes of micropore filling are considered. Reference is also made to more recent work on microporous magnesium oxide which provides excellent confirmation of the ideas previously developed in relation to adsorption by carbon adsorbents.
