Oxygen loop closure is of high priority for an advanced space station air revitalization system. Closure will require the system's CO2 removal and reduction assemblies to be linked; however, the hardware for these two assemblies that is presently considered for use on the
A solid-state, adsorption-based compressor design is being developed at NASA Ames Research Center that meets the requirements of the interface device. The design appears to offer several advantages over mechanical solutions. This article describes the basis for a temperature-swing adsorption compressor and one possible implementation of the device for potential application on the ISS.
