As space organizations across the world look towards human missions to Mars, an effort is needed to advance the technology of a Mars in situ resource utilization (ISRU) Propellant Production Plant to a flight demonstration. Specifically, research is still needed towards the development of a compact and lightweight Microlith-based Sabatier reactor prototype capable of achieving high CO2 conversion and near complete CH4 selectivity at high space velocities. In the Sabatier or CO2 methanation process, CO2 reacts with hydrogen in the presence of catalysts to produce methane and water. The key issue in this application is the reactor design for optimal CO2 conversion, and methane and water production. Previous studies from the literature provides important details about the selection of catalyst, their composition, mechanisms and performance mostly in packed bed reactors. The objective of this study is to numerically investigate the effect of various catalysts for the Sabatier reaction in a micro channel reactor through a set of computational fluid dynamics (CFD) calculations of reaction-coupled thermo-fluid transport phenomena. Three different catalysts are considered: (a)Ni/Al2O3 (b)Ni/Mg/Al2O4 and (c)Ru/Al2O3. Plots of velocity, temperature, as well as CH4 mole fraction at certain temperatures are presented to evaluate the reactor performance for the different catalysts.
