Abstract:
Method for separating a condensable substance from gases or gas mixtures with the use of a porous material comprising the following steps:a. employing a porous material having a pore structure which for capillary condensation is adapted to (i) the environmental or climatic conditions present at the site of utilization (ii) the condensable substance, and (iii) the gases or gas mixtures containing the condensable substance; and b. cyclically performing said method until at least a portion of overall adsorption and desorption is realized by performing a plurality of times in succession separation by capillary condensation in the porous material and desorption of the condensed substance from the porous material; wherein the separation by capillary condensation in the porous material and desorption of the condensed substance from the porous material are performed only in a region of capillary condensation.
