This proposal addresses the fabrication and testing of structured (monolithic), carbon-based multipollutant trace-contaminant (TC) sorbents for the space-suit Exploration Portable Life Support System (xPLSS) used in Extravehicular Activities (EVAs). The proposed innovations: (1) multipollutant trace-contaminant control; (2) thin-walled, structured carbon TC sorbents fabricated using three-dimensional (3D) printing; and (3) the patented low-temperature oxidation step used for the treatment of carbon sorbents. The overall objective: to develop a multipollutant trace-contaminant removal system that is rapidly vacuum-regenerable and that possesses substantial weight, size, and power-requirement advantages with respect to the current state of the art. nbsp;The Phase 1 project successfully demonstrated the effectiveness of monolithic carbon sorbents derived from 3D-printed PEEK polymer with respect to ammonia, formaldehyde, and methyl mercaptan removal at concentrations close to 7-day Spacecraft Maximum Allowable Concentration (SMAC) limits. The sorbent monoliths were also evaluated with respect to carbon-monoxide control, and a path to multipollutant TC control was defined for future Ramp;D. The Phase 2 objectives: (1) to optimize sorbent properties and performance; (2) to design, construct, test, and deliver to NASA two full-scale TC sorbent prototypes; (3) to integrate the full-scale TC Control System (TCCS) with the xPLSS design, and particularly with the Rapid-Cycle Amine (RCA) swing bed for CO2 control. This work will be accomplished in five tasks: (1) Sorbent Development and Optimization; (2) Subscale Sorbent Testing; (3) Full-Scale Prototype Development; (4) Full-Scale Prototype Integration with xPLSS/RCA and Testing; and (5) System Evaluation. The main focus will be full-scale TCCS development and its integration with xPLSS/RCA (Tasks 3 and 4).
