Ethylene, C2H4, is the simplest alkene, a type of hydrocarbon. Ethylene is an important building block used to produce polystyrene, polyethylene, and detergents. Ethylene should be an important product of In-stiu resources utilization.

Ethylene production


Ethylene can be produced on Mars from Ethane by steam cracking or directly by the Fischer-Tropsch reaction. Ethane is produced from CO and Hydrogen in the Fischer-Tropsch reaction. CO is produced from atmospheric CO2 and Hydrogen using the reverse water gas shift reaction. Hydrogen can be obtained through electrolysis of water.


Ethyne is used to create polyethylene by polymerisation.
