Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Sabatier reaction or Sabatier process involves the reaction of hydrogen with carbon dioxide at elevated temperatures and pressures in the presence of a nickel catalyst to produce methane and water. Optionally ruthenium on alumina (aluminum oxide) makes a more efficient catalyst. It is described by the following reaction: CO2 + 4H2 CH4 + 2H2O It was discovered by the French chemist Paul Sabatier. Currently, oxygen generators onboard the International Space Station produce oxygen from water using electrolysis and dump the hydrogen produced overboard. As astronauts consume oxygen, carbon dioxide is produced which must then be removed from the air and discarded as well. This approach requires copious amounts of water to be regularly transported to the space station for oxygen generation in addition to that used for human consumption, hygiene, and other uses a luxury that will not be available to future long duration missions beyond low Earth orbit.
