    摘要: A scavenger for purifying inert gas mixtures to remove Lewis acid and oxidant impurities therefrom, comprising (i) an inert inorganic support, and (ii) an active scavenging species on the support, formed by deposition thereon of an organometallic precursor and pyrolysis thereof at a selected elevated temperature. The organometallic precursor is an alkyl metal compound comprising a metal of Group IA, IIA, and/or IIIA, wherein the pyrolysis temperature may range from about 150.degree. C. to about 250.degree. C., depending on the specific alkyl metal compound employed as the precursor. Also disclosed are: a corresponding method of making the scavenger; a process for purifying inert gases by contacting same with the scavenger; and a vessel containing a bed of the scavenger, useful as an apparatus for purifying inert gases.

    摘要: Process for the separation and purification of oxygen and nitrogen is disclosed which utilizes solutions of oxygen carriers to selectively absorb oxygen from a gaseous stream, leaving nitrogen as a byproduct. In the process, an oxygen carrier capable of reversibly binding molecular oxygen is dissolved in a solvent solution, which absorbs oxygen from an oxygen-containing gaseous feed stream such as atmospheric air and desorbs oxygen to a gaseous product stream. The feed stream is maintained at a sufficiently high oxygen pressure to keep the oxygen carrier in its oxygenated form during absorption, while the product stream is maintained at a sufficiently low oxygen pressure to keep the carrier in its deoxygenated form during desorption. In an alternate mode of operation, the carrier solution is maintained at a sufficiently low temperature and high oxygen pressure to keep the oxygen carrier in its oxygenated form during absorption, and at a sufficiently high temperature to keep the carrier in its deoxygenated form during desorption. Under such conditions, exceptionally high oxygen concentrations on the order of 95% to 99% are obtained, as well as a long carrier lifetime in excess of 3 months, making the process commercially feasible.
