In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio
Chemie Ingenieur Technik, EarlyView.The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from
