The isotherms of the relative linear adsorption deformation of AUK microporous carbon adsorbent are measured during the n-pentane adsorption within the pressure range of 1 Pa to 50 kPa and at temperatures of 243, 273, 293, 313, 353, and 393 K. The curves of adsorption deformation have similar behavior within the whole range of investigated temperatures. Except for the initial pressure range p < 400 Pa, the adsorption deformation increases as pressure grows and reduces as temperature grows. The effects of adsorption deformation manifest extremely weakly at pressures of less than 400 Pa. Nevertheless, in this pressure range, at temperatures below 350 K, the initial compression of adsorbent (0.01%) is observed, which increases as temperature reduces. At higher temperatures, the sharp initial adsorbent expansion by 0.002% is observed, which transfers them to a narrow region of deformation constancy. Beyond this region, the adsorbent expands in all temperature ranges as the pressure increases.
