[edit] oxygen concentrator
A Zeolite bed is the core of an oxygen concentrator. The pressure swing adsorption process uses zeolite as a molecular sieve. Room air is compressed into a zeolite bed, then the remaining air components are drawn off. The bed is then released to atmosphere, the zeolite releases the nitrogen, and the process is restarted. By removing the nitrogen from regular air, you get a mixture of mostly oxygen with traces of carbon dioxide and Argon.
A german company is using those stones to generate cold. Bildunterschrift from Zeotech.
[edit] Uses: Medical
Unless someone can put some citations into that mess of a paragraph about QuikClot to clear up whether it's calcium silicate (which the New Scientist article seems to refute, given that it mentions an alternative to QuikClot being made of calcium and silica) or a zeolite (which the New Scientist article doens't explicitly state), the whole thing should be deleted or remarked out of existence until it can properly cited. dil 18:59, 5 April 2007 (UTC)
[edit] CO2 entrapment
An advance has reportedly been made in "trapping" CO2 molecules in ZIFs, or zeolitic imidazolate frameworks. I'm unsure if it should be covered here as I'm not too well introduced in the subject, but I'm posting the link FYI and also did in the external links section: http://www.scienceblog.com/cms/material-selectively-swallows-co2-15480.html What I'm wondering is if it should have an extra mention in the "Uses" section, or if this is somehow too unrelated for that. — Northgrove 01:03, 15 February 2008 (UTC)
ZIFs are not zeolites. They are a subclass of metal-organic materials that have imidazolate as organic linker and a zeolite-like topology. —Preceding unsigned comment added by 128.40.197.43 (talk) 12:37, 26 February 2008 (UTC)
