Microreactor development for Martian in situ propellant production

A process is presented for in situ resource utilization of indigenous resources on Mars to produce hydrocarbon propellants using microchannel reactors. The proposed system utilizes CO 2 from the atmosphere on Mars and hydrogen brought from Earth. The CO 2 is reacted in a Sabatier reactor (SR) to pro...

Zusammenfassung:	A process is presented for in situ resource utilization of indigenous resources on Mars to produce hydrocarbon propellants using microchannel reactors. The proposed system utilizes CO 2 from the atmosphere on Mars and hydrogen brought from Earth. The CO 2 is reacted in a Sabatier reactor (SR) to produce methane (propellant) and water. The water generated is electrolyzed to produce oxygen (oxidant). The hydrogen is recycled. The microchannel SR used in this study consisted of integrated cooling and reaction channels, was
