Title:
Concept for Increasing Water Recovery by Use of Series Reverse Water-Gas Shift-Sabatier Technology 
Abstract:
A novel concept for increasing the water yield from existing Sabatier technology is proposed. Current Sabatier technology on board the ISS uses electrolysis hydrogen and metabolic carbon dioxide to recover water used for electrolysis. The stoichiometry of the Sabatier reaction requires a hydrogen-to-carbon-dioxide-mole-ratio of 4:1. The mass balance of the ISS however, prescribes a feed ratio of approximately 2:1. As a consequence, water is lost in the form of unreacted CO2. By connecting a reve...    »
