||PCT/US2013/050684||EMPIRE TECHNOLOGY DEVELOPMENT LLC||MILLAR, Benjamin William|
Systems and methods for reducing corrosion of components of a reactor system, such as a supercritical water gasification system are described. A current carrying element may be arranged about the outside surface of a system component, such as a valve, conduit, heater, pre-heater, reactor vessel, and/or heat exchanger. The current carrying element may be in the form of a continuous solenoid, rings, tubes, or rods, including a conductive material, such as copper. A current may be applied to the current carrying element to generate an electromagnetic field within the system component. The current may generate an electromagnetic field within the system component. The electromagnetic field may force corrosive ions moving within a fluid flowing through the system component to move in pathways away from an inner surface of the system component.

||PCT/US2014/047096||CMS TECHNOLOGIES HOLDINGS, INC.||FEIRING, Andrew Edward|
A metal exchanged fluorinated ionomer is a copolymer minimally including repeating units of (i) a polymerized derivative of a perfluorinated cyclic or cyclizable monomer and (ii) a strong acid highly fluorinated vinylether compound in which the acid moiety is exchanged with a cation of a Group 11 metal. Metal exchanged fluorinated ionomers are readily soluble and can be formed into thin, selectively gas permeable membranes by solution deposition methods. These membranes are suitable for separating olefins from gas olefin/paraffin mixtures. Good selectivity and transmembrane flux can be obtained without humidifying the membrane feed gas mixture.
