Technology Marketing Summary

Sandia National Laboratories has developed an economical and efficient activated carbon adsorbent for the trapping of noble gases including Argon, Krypton, Xenon and radioactive 85Kr. Unlike currently used adsorbents, this superior material is fire-resistant with spontaneous ignition temperatures (SIT) of up to 860°C and favorable sorption capacity.

Description

This technology is well suited for a variety of industries including the chemical and petrochemical industries, where such materials are used to control emissions of solvents and other volatile organic compounds from process streams, off-gases and tank venting. Similar applications exist in the environmental engineering, nuclear, military and extraction arenas.

Benefits
  • Significant reduction in risk of fire hazards 
  • Economical and Efficient
  • Reduces risk associated with nuclear fuel reprocessing
  • Broadly applicable to numerous industries
Applications and Industries
  • Mining
  • Nuclear power & fuel processing
  • Waste management
  • Water purification
  • Environmental cleanup 
  • Medical and Chemical Industries

Advanced fire-resistant forms of activated carbon and methods of adsorbing and separating gases using same
Advanced, fire-resistant activated carbon compositions useful in adsorbing gases; and having vastly improved fire resistance are provided, and methods for synthesizing the compositions are also provided. The advanced compositions have high gas adsorption capacities and rapid adsorption kinetics (comparable to commercially-available activated carbon), without having any intrinsic fire hazard. They also have superior performance to Mordenites in both adsorption capacities and kinetics. In addition, the advanced compositions do not pose the fibrous inhalation hazard that exists with use of Mordenites. The fire-resistant compositions combine activated carbon mixed with one or more hydrated and/or carbonate-containing minerals that release H.sub.2O and/or CO.sub.2 when heated. This effect raises the spontaneous ignition temperature to over 500.degree. C. in most examples, and over 800.degree. C. in some examples. Also provided are methods for removing and/or separating target gases, such as Krypton or Argon, from a gas stream by using such advanced activated carbons.
