[SpaceProgram] Challenges of Building A House on Mars

[cole santos]

Biogas process uses Iron oxide to remove sufide gasses.
Gas is pumped through a container of hydrated iron(III) oxide, which
combines with hydrogen sulfide.
Fe2O3(s) + H2O(l) + 3 H2S(g) → Fe2S3(s) + 4 H2O(l)
In order to regenerate iron(III) oxide, the container must be taken
out of service, flooded with water and aerated.
2 Fe2S3(s) + 3 O2(g) + 2 H2O(l) → 2 Fe2O3(s) + 2H2O(l) + 6 S(s)
On completion of the regeneration reaction the container is drained of
water and can be returned to service.
The advantage of this system is that it is completely passive during
the extraction phase.[7]
