摘要： A method recovers an electropositive metal from a metal carbonate. In the method, hydrogen and halogen are combusted to form hydrogen halide. The solid metal carbonate is converted into metal chloride by a gaseous hydrogen halide. In an electrolysis, the metal chloride is decomposed into metal and halogen. The halogen produced in the electrolysis is led out of the electrolysis for combusting. Preferably, the hydrogen halide is produced by combusting the hydrogen and the halogen and the metal carbonate is converted into metal chloride in a fluidized bed reactor. Preferably, lithium is used as the metal.

摘要： Alkali metals and sulfur may be recovered from alkali monosulfide and polysulfides in an electrolytic process that utilizes an electrolytic cell having an alkali ion conductive membrane. An anolyte solution includes an alkali monosulfide, an alkali polysulfide, or a mixture thereof and a solvent that dissolves elemental sulfur. A catholyte includes molten alkali metal. Applying an electric current oxidizes sulfide and polysulfide in the anolyte compartment, causes alkali metal ions to pass through the alkali ion conductive membrane to the catholyte compartment, and reduces the alkali metal ions in the catholyte compartment. Liquid sulfur separates from the anolyte solution and may be recovered. The electrolytic cell is operated at a temperature where the formed alkali metal and sulfur are molten.

摘要： An apparatus, system, and method are disclosed for capturing electrical energy from a process designed for producing hydrogen. An electrode is placed within a stream of liquid alkali metal that flows through a titration module and interacts with water to produce, among other byproducts, hydrogen. Another electrode is placed within a reaction chamber that houses the water. The electrodes can then be coupled to a terminal, and during the hydrogen generation process (when the liquid alkali metal and water interact) the stream of liquid alkali metal acts as an anode and the electrode in the water as a cathode. Current flows, and energy is captured and made available as electrical energy at the terminal, which can be connected to electrical loads. The terminal may be connected with the terminal of a fuel cell that is consuming the hydrogen that is being produced, thus providing additional voltage and/or current.

摘要： Process for preparing an alkali metal from a salt of the alkali metal which is soluble in a solvent, including a first electrolysis, a concentration, and a second electrolysis. The first electrolysis produces a product mixture. This product mixture is then concentrated to give a largely solvent-free alkali metal (poly)sulfide melt. A second electrolysis at a temperature above the melting point of the alkali metal is then performed in a second electrolysis cell comprising an anode space and a cathode space, separated by a solid electrolyte which conducts alkali metal cations. The alkali metal (poly)sulfide melt from the concentration step is fed to the anode space. Sulfur is removed from the anode space and liquid alkali metal is removed from the cathode space.
