Regenerable Carbon Filter

A Regenerable Carbon Filter (RCF) is proposed for the removal of carbonaceous particulate matter produced in Environmental Control and Life Support (ECLS) processes. Successful development of this technology will result in a device that effectively collects ultrafine carbon particles in a high density, high storage capacity volume which is subsequently regenerated in-situ using self-cleaning techniques. Various reactors considered for use in air revitalization in NASA's exploration life support closed habitat mission concepts result in the generation of solid carbon compounds as byproducts. These include the Carbon Formation Reactor (CFR) within a Bosch-type carbon dioxide reduction system and, what the proposed RCF technology specifically addresses, the methane Plasma Pyrolysis Assembly (PPA) within a Sabatier-type carbon dioxide reduction system. Capture and oxidation of this carbon material in a manner that eliminates crew handling while maximizing equipment operating capacity and lifetime is of paramount importance within manned space habitats that rely upon these processes.
