Sabatier process - 2024 ACF Winter at UBC

Question

NASA’s SpaceCraft Oxygen Recovery project utilizes this reaction aboard the International Space Station. For 10 points each:

[10h] Name this reaction in which carbon dioxide and four hydrogen molecules form methane and two water molecules. This reaction is often run in tandem with the reverse water-gas shift reaction to improve efficiency.

ANSWER: Sabatier process [or Sabatier reaction]

[10m] This metal primarily catalyzes the Sabatier process. It’s not cobalt, but Murray Raney names a common hydrogenation catalyst composed of aluminum and a powdered alloy of this element.

ANSWER: nickel [or Ni; accept Raney nickel]

[10e] The selectivity of the Sabatier process has seen use for methanation of trace carbon dioxide produced from hydrogen feed streams in this other industrial process, which converts nitrogen and hydrogen into ammonia.

ANSWER: Haber–Bosch process
