AbstractA novel short contact time Microlith Sabatier reactor system for CO2 reduction offers a significant advance in support of manned spaceflight. Compared to current and prospective alternatives (including microchannels), the reactor will be much smaller and lighter, more energy and resource efficient, and more durable. In the spacecraft cabin atmosphere revitalization system (ARS), the utilization of CO2 to produce life support consumables, such as O2 and H2O, via Sabatier process as part of the CO2 Reduction Assembly (CRA) is an important function for both low-earth orbit and long-term manned space explorations, and also has application for lunar/Martian ISRU concepts. The maturation of this technology will significantly reduce launch weight requirements and the need of re-supply from Earth. Precision Combustion, Inc. (PCI) proposes to build on Phase 1 proof of concept success to develop, demonstrate, and deliver an integrated Microlith<SUP>REG</SUP>-based ground test Sabatier reactor Development Unit (SDU) for CO2 reduction, with collaborative support from a systems integrator. The SDU will convert CO2 and H2 to methane and water, achieving close-to-equilibrium CO2 conversions at high throughputs and at low operating temperatures (?350<SUP>o</SUP>C). Major systems integrator participation will help guide the program. TRL is now 4 and will be advanced to 5.
