The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst. It was discovered by the French chemists Paul Sabatier and Jean-Baptiste Senderens in 1897.

Sabatier Subsystem Overview •Basic system consist of the Sabatier reactor, condenser, and thermal control system •Reactor is used to convert carbon dioxide and hydrogen into methane and water • CO 2 + 4H 2 CH 4 + 2H 2 O • Exothermic, ΔH = -165.4 kJ/mole •Condenser is used to separate the methane and water • Single or multiple ...

As NASA looks towards human missions to Mars, an effort has started to advance the technology of a Mars in situ resource utilization (ISRU) Propellant Production Plant to a flight demonstration. This paper will present a design study of the Sabatier subsystem.

Sep 29, 2021 · The Sabatier process can supplement a power-to-gas method to help create a renewable energy system, alongside wind energy, solar panels that create solar energy, and water energy. The methane created by the Sabatier reaction can be injected directly into a country’s existing gas network.

Precision Combustion, Inc. (PCI) has developed a compact, lightweight Microlith®-based Sabatier (CO2 methanation) reactor which demonstrates the capability of achieving high CO2 conversion and near 100% CH4 selectivity at space velocities of 30,000-60,000 hr-1.

Oct 11, 2023 · Schematic of Methane production system for a Single SpaceX Starship over a period of two years, at about 150 tonnes of methane per year. The Sabatier reaction and water electrolysis are used to convert atmospheric carbon dioxide and water extracted from regolith, or the atmosphere, into propellant.

Oct 3, 2023 · The Sabatier reaction, named after the French chemist Paul Sabatier, is a catalytic hydrogenation reaction that converts CO2 and hydrogen (H2) into methane (CH4) and water (H2O): CO2 + 4H2 → CH4 + 2H2O. This reaction is exothermic, releasing heat as a byproduct.

Jan 4, 2004 · The Sabatier CRA is the next step in closing the oxygen life support loop on future space missions. The Sabatier reaction combines the waste carbon dioxide (recovered from crew metabolism) with waste hydrogen (a byproduct of electrolysis to produce oxygen) to produce water and methane (CH4).

Mar 11, 2019 · In 2011, a Sabatier reaction system was integrated into the International Space Station water recovery system, and a prototype of a Mars in situ propellant production system was demonstrated...

Current technology for the reduction of carbon dioxide to produce water aboard the International Space Station (ISS) is embodied in the Sabatier Reactor. For each mole of carbon dioxide reduced, this system produces two moles of water and one mole of methane.
