Adsorbers for carbon dioxide and other contaminants
PCI is developing air cleaning technologies focused on control of carbon dioxide and other air pollutants.  Microlith® adsorbers offer several advantageous performance features and benefits over other alternative technologies:
  • Direct electrical heating of the substrate utilizing low power
  • Reduced weight and smaller size
  • High energy and conversion efficiency
  • Reduced maintenance and power requirements
  • Improved durability for long term reliable operation
  • Improved adsorbent utilization

Adsorber

PCI is developing specialized zeolite-based adsorbent technologies utilizing the regenerative capabilities of electrically-heated Microlith®.  Under a NASA funded program, an integrated sorber-based Trace Contaminant Control System (TCCS) and Carbon Dioxide Removal Assembly (CDRA) prototype was designed, fabricated and tested.  The technology is focused on adsorbing carbon dioxide, ammonia, ethanol, acetone,toluene and other contaminants from spacecraft cabin air and is targeted to replace currently used activated charcoal and CO2 adsorbent beds.  Potential applications include spacecraft and submarine air cleansing and collective protection shelter air clean-up.
