| Abstract Scope |
CO2 and water vapor removal are critical for air revitalization on the ISS and other confined spaces. A combination of zeolite molecular sieves and silica is used to adsorb CO2, water, and other trace contaminants. These adsorbed contaminants are then expelled by heating the bed to regenerate it. These beds are currently fabricated of loose beads with cartridge heaters and fins for heating. In conjunction with NASA, Mainstream Engineering is developing a process of fabricating sorbent beds with an AM process. We have developed highly-loaded zeolite 13X and silica gel-based pastes that closely mimic the adsorbent capacity of the legacy sorbent beads. We can deposit these pastes into 2.5D and 3D layers optimized for pressure drop, breakthrough capacity, and overall sorbent bed SWaP. Additionally, our patent-pending continuous-wire embedding mechanism allows us to embed thin, high-resistivity wires directly into these printed roads; enabling highly uniform and SWaP-optimized heating of sorbent structures. |
