Closed Sabatier Oxygen-Reclamation System.
Abstract
A Closed Sabatier System for oxygen recovery from carbon dioxide was designed. Design analysis was based on a three-man engineering prototype that consists of the following principal subsystems: a water-vapor electrolysis/Sabatier unit, an electrochemical hydrogen-stripper/Sabatier unit, a continuous catalytic methane decomposition unit, and a water-vapor transfer unit. The electrochemical cell designs utilize Pd-25Ag hydrogen-diffusion electrodes in tubular form containing Sabatier catalyst for integrated system operation. All components are designed for gravity-independent operation with a minimum of critical rotating parts. The electrochemical units operate at about 200C, and the methane decomposition unit at 850C. System weight is about 90 kg with a power requirement of less than 1 kw for designed operation with 99 percent recovery of the oxygen value in the carbon dioxide feed. (Author)
