Abstract
The present invention is a method for separating condensable substances from gases or gas mixtures with the use of porous materials including the steps of employing as adsorbents substances or materials suitable for capillary condensation and cyclically performing the method. The method can be used to separate water from air. The porous materials have a pore structure adapted to the environmental or climatic conditions present at the site of utilization of the method. The step of cyclically performing the method can be performing a plurality of times in succession separation by capillary condensation of the condensable substances in the porous materials and desorption of the condensed substances from the porous materials.
