Patent number: 8865020Abstract: Provided is an adsorbent having superior adsorption properties for use as a dehumidifying agent for desiccant air conditioning which exhibits high adsorption properties at mid and high humidity ranges, and for use as a gas adsorbent of carbon dioxide, ammonia, formaldehyde and the like. A precursor suspension having a Si/Al ratio of 0.70 to 1.0 is prepared, and the precursor suspension is subsequently heated at 110° C. or higher for 2 days to synthesize a complex of a layered low-crystalline clay mineral and an amorphous aluminum silicate. The obtained complex of the layered low-crystalline clay mineral and the amorphous aluminum silicate yields excellent water vapor adsorption performance of 45 wt % or more at a relative humidity of 60%, and therefore can be used as an adsorbent for desiccant air conditioning.Type: GrantFiled: December 26, 2008Date of Patent: October 21, 2014Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Masaya Suzuki, Katsuhiro Tsukimura, Sumiko Kawabata, Chieko Ikeda, Ryousuke Nakanishi, Koji Tajiri, Keiichi Inukai, Masaki Maeda

Patent number: 8852322Abstract: A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.Type: GrantFiled: February 27, 2012Date of Patent: October 7, 2014Assignee: Exxonmobil Research and Engineering CompanyInventors: Ramesh Gupta, Harry W.

Publication number: 20140274659Abstract: Adsorbed natural gas (ANG) technology is an energy efficient approach for storing NG at room temperature and low pressure. ANG technology can be applied to several aspects of the NG industry. The usage of an adsorbent material in natural gas storage and transport may provide increased storage density of NG at a given pressure and decreased pressure of gaseous fuel at a given gas density. Such adsorbent materials have been shown to store substantial quantities of natural gas at relatively modest pressures. Because lower-pressure vessels can be far less expensive than comparable sized high-pressure vessels, ANG based storage can be used to lower the cost of storing natural gas in various applications.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: OSCOMP SYSTEMS INC.Inventors: Jimmy ROMANOS, Pedro T.

Patent number: 8834822Abstract: A method for the separation of carbon dioxide from ambient air and flue gases is provided wherein a phase separating moiety with a second moiety are simultaneously coupled and bonded onto an inert substrate to create a mixture which is subsequently contacted with flue gases or ambient air. The phase-separating moiety is an amine whereas the second moiety is an aminosilane, or a Group 4 propoxide such as titanium (IV) propoxide (tetrapropyl orthotitanate, C12H28O4Ti). The second moiety makes the phase-separating moiety insoluble in the pores of the inert substrate. The new sorbents have a high carbon dioxide loading capacity and considerable stability over hundreds of cycles. The synthesis method is readily scalable for commercial and industrial production.Type: GrantFiled: August 18, 2011Date of Patent: September 16, 2014Assignees: Georgia Tech Research Corporation, U.S. Department of EnergyInventors: McMahan Gay, Sunho Choi, Christopher W.
