测定了AR-V微孔碳吸附剂在1 Pa ~ 14 kPa压力范围和255 ~ 353 K温度范围内对苯的吸附等温线和吸附引起的变形。在低压区，在333和353 K温度下，AR-V吸附剂发生收缩，随着压力的增加，收缩变为膨胀。在低温区（255-313 K），在整个研究压力范围内，只观察到AR-V吸附剂的膨胀。吸附剂的最大相对压缩值在0.18% ~ 0.08%之间变化，对应温度在353 ~ 333 K之间变化。随着相应温度从293 ~ 353 K的升高，最大相对膨胀率从0.9 ~ 0.05%变化。
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 lowpressure 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 corresponding 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.
