    摘要： A method and apparatus for top-charging a solid waste into a molten metal bath to form a dissociation product are disclosed. The method includes introducing the waste into the molten metal bath through a refractory tube disposed in a reactor, containing the molten metal bath, through which the refractory tube extends. A gas outlet is disposed above the molten metal bath. The refractory tube has a submergible end which is immersed in the molten metal bath and which defines a lower opening at the terminal end of the refractory tube and an elevated opening, whereby a portion of the molten metal bath enters the refractory tube through the lower opening to allow the molten metal bath to remain within the refractory tube while at least partially dissociating the waste to form the dissociation product in the molten metal bath. An oxidizing agent can be directed into the molten metal bath at a rate sufficient to form an gaseous oxygenated product which is discharged from the reactor.

    摘要： 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.

    摘要： 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. The rate at which the second reducing agent is directed into the molten metal bath, relative to the rate at which the component of the waste is directed into the molten metal bath, is sufficient to cause essentially all metal-containing intermediate formed to dissolve in the molten metal bath, thereby indirectly chemically reducing the component of the waste. This indirect reduction technology can remediate a variety of materials, including ash metal-contaminated municipal waste, vitreous slag-like materials and spent metal catalysts, while allowing the recovery of remediable metals.
