Martin Bulow, Loc Dao, Frank R Fitch: Removal of carbon dioxide from gas streams. The BOC Group, Coleman R Reap, Larry R Cassett, December 24, 1996: US05587003 (57 worldwide citation)

Carbon dioxide is removed from a gas stream by passing the gas stream through a bed of natural or synthetic clinoptilolite or their chemically-modified derivatives. The process is particularly advantageous when applied to the removal of ppm levels of carbon dioxide from gas streams at temperatures a ...
