“…One of the coated technologies currently under evaluation is the sorbent version Microlith TM developed by Precision Combustion Incorporated (PCI) [2,3] The sorbent version is an extension of successful work on Microlith TM based oxidation catalysts [4]. The sorbent version of the technology consists of sorbent material coated onto an expanded metal screen.…”

In NASA's Vision for Space Exploration, humans will once again travel beyond the confines of earth's gravity, this time to remain there for extended periods. These forays will place unprecedented demands on launch systems. They must not only blast out of earth's gravity well as during the Apollo moon missions, but also launch the supplies needed to sustain a larger crew over much longer periods. Thus all spacecraft systems, including those for the separation of metabolic carbon dioxide and water from a crewed vehicle, must be minimized with respect to mass, power, and volume. Emphasis is also placed on system robustness both to minimize replacement parts and ensure crew safety when a quick return to earth is not possible. This paper describes efforts to improve on typical packed beds of sorbent pellets by making use of structured sorbents and alternate bed configurations to improve system efficiency and reliability.The development efforts described offer a complimentary approach combining testing of subscale systems and multiphysics computer simulations to characterize the regenerative heating substrates and evaluation of engineered structured sorbent geometries. Mass transfer, heat transfer, and fluid dynamics are included in the transient simulations.

“…Beginning in 1992, NASA-sponsored projects began to apply the Microlith ® catalytic oxidation technology developed by Precision Combustion, Inc. (PCI) for automotive and gas turbine engine emissions control to crewed spacecraft trace contaminant control challenges. [1][2][3][4] The Microlith ® substrate is patented and trademarked by PCI. 5 Following the successful catalytic oxidation technology development, attention turned to the challenge of developing more energy efficient, durable adsorbent media for combined vacuum-temperature swing regenerable processes suited for broad spectrum crewed spacecraft cabin atmosphere quality control (AQC) applications.…”

Engineered structured (ES) sorbents are being developed to meet the technical challenges of future crewed space exploration missions. ES sorbents offer the inherent performance and safety attributes of zeolite and other physical adsorbents but with greater structural integrity and process control to improve durability and efficiency over packed beds. ES sorbent techniques that are explored include thermally linked and pressure-swing adsorption beds for water-save dehumidification and sorbent-coated metal meshes for residual drying, trace contaminant control, and carbon dioxide control. Results from sub-scale performance evaluations of a thermally linked pressure-swing adsorbent bed and an integrated sub-scale ES sorbent system are discussed. Nomenclature
