Title: Carbon fiber composite molecular sieve electrically regenerable air filter media

Abstract

An electrically regenerable gas filter system includes a carbon fiber composite molecular sieve (CFCMS) filter medium. After a separate medium-efficiency pre-filter removes particulate from the supply airstream, the CFCMS filter sorbs gaseous air pollutants before the air is recirculated to the space. When saturated, the CFCMS media is regenerated utilizing a low-voltage current that is caused to pass through the filter medium.

Bonded carbon or ceramic fiber composite filter vent for radioactive waste

Patent Brassell, Gilbert W [13237 W. 8th Ave., Golden, CO 80401]; Brugger, Ronald P [Lafayette, CO]

Carbon bonded carbon fiber composites as well as ceramic or carbon bonded ceramic fiber composites are very useful as filters which can separate particulate matter from gas streams entraining the same. These filters have particular application to the filtering of radioactive particles, e.g., they can act as vents for containers of radioactive waste material.

CTR Fuel recovery system using regeneration of a molecular sieve drying bed

Patent Folkers, Charles L [Livermore, CA]

A primary molecular sieve drying bed is regenerated by circulating a hot inert gas through the heated primary bed to desorb water held on the bed. The inert gas plus water vapor is then cooled and passed through an auxiliary molecular sieve bed which adsorbs the water originally desorbed from the primary bed. The main advantage of the regeneration technique is that the partial pressure of water can be reduced to the 10.sup.-9 atm. range. This is significant in certain CTR applications where tritiated water (T.sub.2 O, HTO) must be collected and kept at very low partial pressure.

Method and apparatus for separating gases based on electrically and magnetically enhanced monolithic carbon fiber composite sorbents

Patent Judkins, Roddie R [9917 Rainbow Dr., Knoxville, TN 37922]; Burchell, Timothy D [109 Greywood Pl., Oak Ridge, TN 37830]

A method for separating gases or other fluids involves placing a magnetic field on a monolithic carbon fiber composite sorption material to more preferentially attract certain gases or other fluids to the sorption material to which a magnetic field is applied. This technique may be combined with the known "pressure swing adsorption" technique utilizing the same sorption material.

Regenerable Carbon Fiber Composite Molecular Sieves for Scrubbing CO₂ from Air

Conference Contescu, Cristian I [ORNL]; Baker, Frederick S [ORNL]; Gallego, Nidia C [ORNL]; ...

More effective and convenient methods for scrubbing carbon dioxide from gas streams are required for a range of applications, from purification of air to removal of carbon dioxide from fuel and syngas streams for fuel cells. In this paper, recent results on the development of three-dimensional carbon fiber composite molecular sieve (CFCMS) material as a selective, regenerable adsorbent for removing CO2 (and other small molecules) from air and other gas streams will be presented. CFCMS is a contiguous monolithic carbon structure that can be activated to various levels for tunable adsorption properties, and can be regenerated through a combination ofmore » « less
