(359b) On the Use of Structured Adsorbents in Ptsa Cycles for CO2 Removal from Spacecraft Cabins
Two different structured adsorbents are being considered. One consists of a steel foil support coated with a layer of 13X crystals that is being developed by Catacel and the other consists of a metal microfibrous media with entrapped ground and sieved 13X adsorbent particles. These tow structured adsorbents are being contrasted against traditional beaded 13X. This study is evaluating the performance in terms of CO2/N2 inside the bed and outside the bed breakthrough curves, and CO2 removal during PTSA cyclic operation. The latest results of this project will be presented.
