Conclusion
The dilatometric changes of carbon adsorbents as a result of water vapor adsorption-desorption cycles are irreversible and depend on the temperature of the initial dehydration. After an adsorption-desorption cycle, the granules remain expanded if the evacuation is carried out at 293 K and are irreversibly compressed if the dehydration is carried out at 623 K.
