Patent number: 9956520Abstract: A carbon dioxide absorbent composition is described, including (i) a liquid, nonaqueous silicon-based material, functionalized with one or more groups that either reversibly react with CO2 or have a high-affinity for CO2, and (ii) a hydroxy-containing solvent that is capable of dissolving both the silicon-based material and a reaction product of the silicon-based material and CO2. The absorbent may be utilized in methods to reduce carbon dioxide in an exhaust gas, and finds particular utility in power plants.Type: GrantFiled: September 9, 2016Date of Patent: May 1, 2018Assignee: General Electric CompanyInventors: Robert James Perry, Grigorii Lev Soloveichik, Malgorzata Iwona Rubinsztajn, Michael Joseph O'Brien, Larry Neil Lewis, Tunchiao Hubert Lam, Sergei Kniajanski, Dan Hancu

Patent number: 8435673Abstract: A cathode composition and a rechargeable electrochemical cell comprising same are disclosed. The cathode composition is described as comprising particles of one or more transition metal, alkali halometallate having a melting point of less than about 300 degrees Celsius, and at least one phosphorus composition additive selected from P—O compositions, P-halogen compositions, P—O-halogen compositions, and their reaction products and combinations. Also described is a rechargeable electrochemical cell comprising the composition. The phosphorus composition additive in the cathode composition of a cell is effective to lower the capacity degradation rate of the cell during operation relative to absence of the additive, and effective to lower the internal resistance of the cell when under operating conditions relative to absence of the additive.Type: GrantFiled: April 30, 2009Date of Patent: May 7, 2013Assignee: General Electric CompanyInventors: John Patrick Lemmon, Jun Cui, Malgorzata Iwona Rubinsztajn, Richard Louis Hart, Jennifer Kathleen Redline

Patent number: 8030509Abstract: In accordance with one aspect, the present invention provides an amino-siloxane composition comprising at least one of structures I, II, III, IV or V said compositions being useful for the capture of carbon dioxide from gas streams such as power plant flue gases. In addition, the present invention provides methods of preparing the amino-siloxane compositions are provided. Also provided are methods for reducing the amount of carbon dioxide in a process stream employing the amino-siloxane compositions of the invention as species which react with carbon dioxide to form an adduct with carbon dioxide. The reaction of the amino-siloxane compositions provided by the present invention with carbon dioxide is reversible and thus, the method provides for multicycle use of said compositions.Type: GrantFiled: July 30, 2009Date of Patent: October 4, 2011Assignee: General Electric CompanyInventors: Robert James Perry, Larry Neil Lewis, Michael Joseph O'Brien, Grigorii Lev Soloveichik, Sergei Kniajanski, Tunchiao Hubert Lam, Julia Lam Lee, Malgorzata Iwona Rubinsztajn

Publication number: 20080261098Abstract: A method for making a proton-conducting membrane is described. The method includes the steps of combining a protonated, layered inorganic material with a proton-conducting organic polymer in a liquid medium; exfoliating the layered inorganic material, so that individual layers of the inorganic material are suspended in the liquid medium and spaced from each other; and the polymer is absorbed onto the surface of the individual layers. In this manner, a polymer-inorganic composite is formed. The liquid can then be removed, to recover the resulting membrane. Related electrolysis and fuel cell devices are also described, which incorporate the proton-conducting membrane.Type: ApplicationFiled: April 20, 2007Publication date: October 23, 2008Applicant: GENERAL ELECTRIC COMPANYInventors: John Patrick Lemmon, Malgorzata Iwona Rubinsztajn, Richard Louis Hart
