Regenerable Air Filter Media for Adsorption of Toxic Industrial Chemicals

Precision Combustion, Inc. (PCI) proposes to develop a new compact, high efficiency and regenerable adsorption media and system technology for capturing toxic industrial chemicals (TIC) to provide continuous collective protection for DoD infrastructure. This technology will be based upon our novel proprietary high mass and heat transfer adsorption material support elements, originally developed for cabin atmosphere revitalization systems for spacecraft and space station applications, which was demonstrated to be superior (i.e., lower power consumption, lighter, and smaller size) to existing technologies such as pellets and monoliths. Additionally, this technology offers the benefits of rapid in-situ regeneration, high adsorbent utilization, longer adsorbent life, design modularity, and adsorbent flexibility as well as tunability and control of desorption rate and adsorbent bed temperature. In Phase 1, a proof-of-concept of an adsorbent air filter will be developed to demonstrate thermal stability and ability to maintain>90% adsorption activity following exposures to 100 ppmv TIC agent at temperatures of>20 degrees C and relative humidity of 65% for at least 5 adsorption-desorption cycles. Additionally, the prototype ability to capture and release the TIC challenge gas with tunable adsorption and regeneration kinetics will be demonstrated.
