Current approaches planned for space suit atmosphere revitalization (AR) are neither compatible with each other nor regenerable in space, and have a high life cycle operating cost associated with them. The proposed PCI innovation in collaboration with University of Hartford involves synthesizing improved sorbents on high surface area supports tailored for CO2, water and trace contaminant removal. Phase I effort will demonstrate proof of concept?developing appropriate methods for coating high capacity sorbents on high surface area supports, scalability of the approach with high bed utilization, maximizing sorption capacity resulting in ultra-compact sorption adsorber, rapid regeneration to vacuum and an operating demonstration on a bench scale; representing significant advances over current state-of-the art AR methods.
