Abstract

A comparison of both isosteric and differential heats of single gas adsorption on microporous active carbons has been undertaken. The experimental data obtained indicate strong differences between the analysed quantities for the studied adsorbents. It is deduced from thermodynamical considerations that a molecular sieve effect is responsible for these differences.
