Conclusions
-
1.
Adsorption isotherms of cyclopentane on commercial activated charcoal of the AG type obtained by vapor-gas activation of coal raw material were measured in the temperature interval from 298 to 343 K and equilibrium pressures from 10−1 to 1000 Pa.
-
2.
The appearance of low-pressure hysteresis was detected under the given conditions. The position of the joining point of the hysteresis branches depends on temperature and shifts with a temperature increase into the region of lower pressures.
-
3.
The phenomenon of low-pressure hysteresis in the given system is basically connected with reduced (slowed) penetration of the adsorbate into the pores of charcoal, which are close in size to the size of the adsorbate molecules.
