Major concern to reduce power consumption of this process. Air drying can be achieved by Temperature and Vacuum Swing Adsorption. On fast cycles, the use of structured adsorbents5 could be a way to significantly improve the efficiency and the compactness of adsorbers. In this paper, structured adsorbents with a very small characteristic length are densely packed in an adsorber. In the frame of a CNES contract to assess performances of this technology for trapping water, lab tests are dealt to evaluate the drying power of this tailor made desiccant. The obtained performances are compared with the ones produced with classical drying solution based on beads desiccant. A substantial gain in terms of yield and compactness is to be underlined, showing the interest to improve adsorption kinetics working on thinner adsorbents with a good mechanical resistance to attrition. In addition, future perspectives for life support systems will be presented especially with the capability to trap carbon dioxide as well as water.
