Abstract:
Embodiments disclose re-generating a configuration command of a network device. A method includes receiving a request to re-generate a configuration command previously issued to a network device, wherein the configuration command has one or more parameters; retrieving a template and a pattern associated with the configuration command, wherein the template represents a syntax for the configuration command, wherein the pattern represents a storage location for the configuration command; based on the pattern, retrieving from an object database all objects containing values for all the particular parameters from the storage location specified by the pattern; and creating a re-generated configuration command by substituting the values of the retrieved objects into the template.
Abstract:
A method for separating a hydrogen-rich product stream from a feed stream comprising hydrogen and at least one carbon-containing gas, comprising feeding the feed stream, at an inlet pressure greater than atmospheric pressure and a temperature greater than 200° C., to a hydrogen separation membrane system comprising a membrane that is selectively permeable to hydrogen, and producing a hydrogen-rich permeate product stream on the permeate side of the membrane and a carbon dioxide-rich product raffinate stream on the raffinate side of the membrane. A method for separating a hydrogen-rich product stream from a feed stream comprising hydrogen and at least one carbon-containing gas, comprising feeding the feed stream, at an inlet pressure greater than atmospheric pressure and a temperature greater than 200° C., to an integrated water gas shift/hydrogen separation membrane system wherein the hydrogen separation membrane system comprises a membrane that is selectively permeable to hydrogen, and producing a hydrogen-rich permeate product stream on the permeate side of the membrane and a carbon dioxide-rich product raffinate stream on the raffinate side of the membrane. A method for pretreating a membrane, comprising: heating the membrane to a desired operating temperature and desired feed pressure in a flow of inert gas for a sufficient time to cause the membrane to mechanically deform; decreasing the feed pressure to approximately ambient pressure; and optionally, flowing an oxidizing agent across the membrane before, during, or after deformation of the membrane. A method of supporting a hydrogen separation membrane system comprising selecting a hydrogen separation membrane system comprising one or more catalyst outer layers deposited on a hydrogen transport membrane layer and sealing the hydrogen separation membrane system to a porous support.
Abstract:
A method for separating hydrogen from a high pressure gas containing hydrogen and carbon dioxide using a vanadium/nickel alloy membrane having a palladium coating, the membrane containing from zero up to about 10 atomic percent nickel, and having a thickness of from about 75 to about 500 microns. The membrane is employed at a temperature of from about 300 to about 440° C., under a pressure of from about 250 to about 500 psia, and a hydrogen partial pressure gradient across the membrane is maintained to provide a hydrogen partial pressure on the permeate side of the membrane of from about 0.02 to about 2 psia.
Abstract:
Composite hydrogen transport membranes used for extraction of hydrogen from gas mixtures are provided. Membranes are described comprising metals and metal alloys which exhibit high hydrogen permeability and which exhibit resistance to differential pressures across the membrane and wherein the metals and alloys are protected from embrittlement by hydrogen. Support materials of the membranes are selected in some cases to be lattice matched to the metals and alloys. In specific embodiments, membranes useful in the invention contain binary, ternary or quaternary alloys of vanadium which exhibit high hydrogen permeability and improved strength and/or longevity in application.

Abstract:
Aspects of the invention include methods for producing purified semiconductor or metallic materials. In one embodiment, the methods include admixing a particulate composition of a material, for instance, a metal, with a metal halide to produce a metal-metal halide admixture. The admixture is then heated to a temperature that is above the material's melting point in a container that is chemically and physically stable at that temperature. The molten admixture is allowed to segregate into a lower of the material and an layer of the metal halide and cooled. The metal halide is then separated from the material and a purified semiconductor or metallic material is thereby produced. Also provided are purified material crystals, shaped ingots and/or taper, sheet, or ribbons produced by such methods, as well as the silicon chips and solar panels in which such products are employed.
