Adsorption isotherms of benzene and adsorption induced deformation of the AR V microporous carbon adsorbent in the pressure range from 1 Pa to 14 kPa and at temperatures from 255 to 353 K have been determined. Contraction of the AR V adsorbent is observed at temperatures of 333 and 353 K in the low pressure area, which changes into expansion with an increase in pressure. In a low temperature area (255-313 K), only expansion of the AR V adsorbent is observed in the whole range of the studied pressures. The value of the maximal relative compression of the adsorbent changes from 0.18 to 0.08%, while the corre sponding temperature varies from 353 to 333 K. The maximal relative expansion changes from 0.9 to 0.05% along with an increase in the corresponding temperature from 293 to 353 K.

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.
