  • Patent number: 8808411
    Abstract: Disclosed is a process for making a high-purity gas. The process includes an interrelationship among at least four bath vessels, each of which has a molten metal bath. In one embodiment, the process generally includes adding a gas stream into a first bath vessel and then removing that gas stream to introduce it into a third bath vessel. The third bath gas stream is removed to ultimately obtain hydrogen. Steam is added to a fourth bath vessel to ultimately produce additional hydrogen. One or more gas streams produced in the third and/or fourth bath vessels are added to a second bath vessel to ultimately result in production of methane or carbon monoxide.

  • Patent number: 6096109
    Abstract: A method for converting a ligated-metal into chemical components of the ligated-metal includes forming an ionized zone that can convert the ligated-metal to a reduced ligated-metal intermediate. The ligated-metal is directed into the ionized zone, whereby the ligated-metal is converted to a reduced ligated-metal intermediate, thereby causing a thermodynamically stable metal-ligand bond of the ligated-metal to be electronically destabilized and inducing subsequent metal-ligand bond rupture. The reduced ligated-metal intermediate is converted by the metal-ligand bond rupture into chemical components of the ligated-metal. Ligated-metals that are suitable for processing by the method of the invention include, for example: uranium hexafluoride (UF.sub.6); sodium chloride (NaCl); and metal halides, such as iron trichloride (FeCl.sub.3). Chemical components that can be recovered from the ligated-metal include, for example, metals and gases derived from the ligand component of the ligated-metals.

  • Patent number: 5717149
    Abstract: A method and apparatus producing halogenated products from metal halide feeds. In one embodiment, uranium hexafluoride is treated by separating fluorine from the metal of the uranium hexafluoride. Uranium hexafluoride is introduced into a molten metal bath under conditions whereby the uranium hexafluoride in the presence of hydrogen and oxygen can react to form a uranium dioxide and anhydrous hydrogen fluoride. The anhydrous hydrogen fluoride is removed from the molten metal bath as a gas stream and the uranium dioxide is discharged as a ceramic phase.

  • Patent number: 5640707
    Abstract: A method includes organic homologation employing an organic-containing feed. The organic-containing feed is directed into a molten metal bath. The molten metal bath includes a metal which can cause an organic component of the organic-containing feed to homologate and form a homologated organic compound. Operating conditions are established and maintained in the reactor to cause the organic component to form a homologated organic compound that is discharged from the molten metal bath.

  • Patent number: 5629464
    Abstract: The invention relates to a method for producing an unsaturated organic compound from an organic-containing feed. The method includes providing a reactor containing a liquid bath which includes a Bronsted acid that can protonate an organic component of the organic-containing feed. The feed is directed into the liquid bath at a rate which causes the Bronsted acid to protonate the organic component. Conditions are established and maintained in the reactor which cause the protonated organic component to fragment and form a carbenium ion and an unsaturated organic compound, whereby the unsaturated organic compound is discharged from the liquid bath.

  • Patent number: 5543558
    Abstract: A method includes producing an unsaturated organic compound from an organic component of an organic-containing feed. A reactor is provided which contains a molten metal bath. The molten metal bath includes a metal, such as a suitable transition metal, which can interact with an organic component of the feed. The feed is directed into the molten metal bath at a rate which causes the metal to interact with the organic component. Operating conditions are established and maintained in the reactor to cause the metal to interact with the organic component. At least one carbon-carbon double bond is formed in the organic component to produce an unsaturated organic compound that is discharged from the molten metal bath.

  • Patent number: 5489734
    Abstract: A method is disclosed for producing a non-radioactive product from a radioactive waste composition that includes a radioactive component and a non-radioactive component. The method includes directing the radioactive waste into a molten metal bath. A separation agent is directed in the molten metal bath which reacts with a component of the radioactive waste composition to form a reaction product which separates from the remaining component, thereby forming a non-radioactive product. The separation reagent can be, for example, an oxidant, a metal-ligand exchange reagent, or a reducing agent. The non-radioactive product can be a gas, a liquid, or a precipitate.

  • Patent number: 5358549
    Abstract: An environmentally sound process is described for the remediation of waste materials that allows the separation, recovery and decontamination of metals. The method includes chemically reducing essentially all of a reducible toxic and potentially hazardous metal-containing component of a waste composition. The waste is directed into a molten metal bath, including a first reducing agent which, under the operating conditions of the molten metal bath, chemically reduces a metal of the metal-containing component to form a dissolved intermediate. A second reducing agent is directed into the molten metal bath. The second reducing agent, under the operations of the molten metal bath, chemically reduces the metal of the dissolved intermediate.

  • Patent number: 5324341
    Abstract: An environmentally sound process is described for the remediation of waste materials and oxides of metals that allows the separation, recovery and decontamination of metals. The method includes chemically reducing essentially all of a reducible toxic and potentially hazardous metal oxide of a metal-containing composition. A metal-containing composition is directed into a molten bath, including a first reducing agent which, under the operating conditions of the molten bath, chemically reduces a first metal oxide of a metal in the metal-containing composition to form a bath-soluble transient second metal oxide. A second reducing agent is directed into the molten bath. The second reducing agent, under the operations of the molten-bath, chemically reduces the second metal oxide, provided that the second reducing agent has a Gibbs free energy lower than that of the second metal oxide.

  • Patent number: 5202100
    Abstract: A method is disclosed for reducing the volume of a radioactive composition by separating a radioactive first component from a second component of the radioactive composition. The method includes directing the radioactive composition into a reaction zone. The reaction zone includes a molten bath, wherein oxidation of a component of the radioactive composition in the molten bath will cause separation of the radioactive first component from the second component. An oxidizing agent is directed into the molten bath, which oxidizes a component of the radioactive composition, whereby the radioactive first component is separated from the second component. The net volume of the radioactive composition is thereby reduced.
