Data on variation of linear sizes of AP B adsorbent granules under physical adsorption of ben zene, n hexane, n nonane, tetrachloride carbon, and mixtures thereof within the temperature range of from 423 to 473 K were presented for equilibrium and nonequilibrium conditions. It was shown that waves of adsorption deformation of adsorbents-waves of sorbostriction-appeared at a certain selection of adsorp tion parameters.
