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.
A method for top-charging a solid waste into a molten metal bath contained in a reactor, wherein the solid waste is dissociated into dissociation products that are subsequently oxidized to form a gaseous oxygenated product, comprising introducing said waste into the reactor through a refractory tube that extends within the reactor and into the molten metal bath, said refractory tube having a submergible end that is immersed in the molten metal bath and that has a lower opening at a terminal portion of the submergible end and at least one elevated opening, whereby a portion of the molten metal bath enters the refractory tube through the lower opening for dissociating the waste and for forming the gaseous oxygenated product, the gaseous oxygenated product passing out of the refractory tube through said elevated opening and being discharged from the reactor through a reactor outlet disposed above the molten metal bath.
