A membrane Sabatier system for water recovery and rocket propellant production.

ABSTRACT: One significant obstacle to the colonization of Mars is the high cost of excess launch mass required for long-term space travel and the establishment of a settlement. The Sabatier reaction provides a means for recycling water and rocket propellant that dramatically reduces the supplement. Herein, we introduce a membrane Sabatier system by integrating a catalytic reactor with an H₂O vapor permselective membrane tube. We achieve a substantial increase in CO₂ conversion, a high CH₄ yield and excellent long-term stability via highly efficient in-situ water removal. Furthermore, the system's robustness under intermittent power supplies, and its adaptability across a wide range of reaction conditions, makes it highly compatible with the electrolytic hydrogen prod
