Gas Phase Sulfur Adsorption Beds
The presence of sulfur in a gas stream in the form of hydrogen sulfide is well known to poison hydrogen separation membranes as well as many fuel cell stacks. Precision Combustion Inc. has developed sulfur adsorber module prototypes that can reduce the quantity of H2S in a gas stream to less than 1 PPM. Depending upon the quantity of sulfur in the fuel stream, beds can be manufactured to last from hundreds of hours through many thousands of hours without requiring regeneration or replacement.
AIR CLEANERS
The unit shown is a sulfur adsorption bed for high pressure/high flow applications such as may be found in a fuel processing system for a fuel cell power generator.

Microlith® Adsorbers for Carbon Dioxide and Water
PCI is developing air cleaning technologies focused on control of carbon dioxide and other air pollutants.
Performance Benefits of Catalytic Air Cleaners
Microlith® catalytic air cleaners offer several performance benefits over alternative technologies.
- Ultra-compact size and low weight
- Direct electrical heating of the conductive substrate utilizing low power
- High energy and conversion efficiency
- Reduced maintenance and power requirements
- Improved durability for long term reliable operation
CO2 Adsorbers
PCI is developing specialized zeolite-based adsorbent technologies utilizing the regenerative capabilities of resistively-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.

Applications
AIR CLEANERS
PCI advanced Microlith® based catalytic oxidizers for trace air contaminant control (TCCS) aboard the International Space Station have been provided under contract to NASA for qualification testing, offering substantial weight savings in a compact space. Other benefits include the ability to target individual species for cleanup and ready integration with existing systems.
This technology has been successfully tested for oxidizing trace amounts of space station air contaminants e.g. isopropanol, butanol, acetone, toluene, methane, 2-ethoxyethanol, octaflouropropane and sulfur hexaflouride. Duration testing of the prototype unit has been performed resulting in over 16,000 hours of cumulative operation without degradation in methane oxidation efficiency (~98%).
