Publication number: 20080184883Abstract: A metal-organic framework-based mesh-adjustable molecular sieve (MAMS) exhibiting a temperature-dependent mesh size. The MAMS comprises a plurality of metal clusters bound with a plurality of amphiphilic ligands, each ligand comprising a hydrophobic moiety and a functionalized hydrophilic moiety, and wherein the metal clusters and amphiphilic ligand functionalized hydrophilic moieties form a metal cluster layer, the metal cluster layer forming at least one hydrophilic pore. On each side of the metal cluster layer, a plurality of associated amphiphilic ligand hydrophobic moieties cooperate with the metal cluster layer to form a tri-layer and a plurality of tri-layers are packed in a facing-spaced apart relationship to form at least one hydrophobic pore.Type: ApplicationFiled: April 23, 2007Publication date: August 7, 2008Applicant: Miami UniversityInventors: Hong-Cai Zhou, Shengqian Ma

Patent number: 7368000Abstract: A method is described for recovering a noble gas, such as xenon or krypton, from a first gas mixture comprising a plurality of components, one of which is the noble gas and the others are typically helium and/or nitrogen, argon, and relatively light fluorocarbons. The gas mixture is first conveyed to a gas chromatography column for separating the noble gas from the other components of the gas mixture. As the noble gas travels relatively slowly through the column, the other components are exhausted from the column before the relatively slow noble gas. Following the exhaust of these other components, a purge gas is supplied to the column to flush the noble gas therefrom. A second gas mixture comprising the noble gas and the purge gas is conveyed from the column to a membrane separator to separate the second gas mixture into a noble gas-rich gas stream and a purge gas-rich gas stream, which may be recirculated back to the column for re-use.Type: GrantFiled: December 22, 2004Date of Patent: May 6, 2008Assignee: The BOC Group plcInventors: Ravi Jain, Julian Richard Dean, Robert Bruce Grant, Naum Perelman, Paul Alan Stockman, Neil Condon, Andrew John Harpham, William R. Gerristead, Jr.

Patent number: 7300497Abstract: A gas separation method is provided in which, when separating a first component and a second component from a mixed gas containing a plurality of components by using a pressure swing adsorption method, these components can be efficiently recovered and cost reduction can be achieved. Between an adsorption step and a regeneration process step, which use a first adsorption column containing a first adsorbent on which the first component is less readily adsorbable and the second component is absorbable, and a second adsorption column containing a second adsorbent on which the first component is readily adsorbable and the second component is less readily adsorbable, an equalization depressurization step and an equalization pressurization process step, in which the pressure of the first and second adsorption columns is equalized, is carried out.Type: GrantFiled: April 11, 2003Date of Patent: November 27, 2007Assignee: Taiyo Nippon Sanso CorporationInventors: Tatsushi Urakami, Tooru Nagasaka, Masato Kawai, Akihiro Nakamura
