Application to Lunar Colonization
Proposed Uses
Carbon would be required for the production of lunar steel. In addition, use of carbon has been proposed for a number of lunar industrial procedures, both as a reactant and as an electrode material. Examples include aluminum and titanium production.
Lunar Occurrence and Production
Carbon is present in the lunar regolith. Estimates of its concentration range from 80 to over 200 parts per million, depending on location. This carbon could be extracted by heating the regolith, causing carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4) to form, which are then collected (see Volatiles). These substances would have to be reduced further to produce elemental carbon.
