Integrated system for oxygen recovery for deep space mission

An environmental control system, comprising:

• a carbon dioxide source;
• a compressor downstream of the carbon dioxide source;
• a Sabatier reactor downstream of the compressor, wherein the Sabatier reactor reacts carbon dioxide with hydrogen;
• a water separator downstream of the Sabatier reactor, wherein the water separator separates hydrocarbons from water, wherein the hydrocarbons include methane and ethane;
• a pyrolysis assembly downstream of the water separator and upstream of the compressor, wherein the pyrolysis assembly includes a pre-form that adheres carbon, wherein the pyrolysis assembly pyrolyzes methane;
• an oxygen generating assembly (OGA) directly downstream of the water separator, wherein the OGA electrolyzes water;
• wherein hydrogen produced from the OGA mixes with carbon dioxide exiting the compressor and before the exiting carbon dioxide enters the Sabatier reactor.
