  • Patent number: 8199790
    Abstract: Disclosed herein is a reactor vessel for plasma gasification reactors employing a DC graphite electrode, AC graphite electrodes, AC plasma torches or DC plasma torches to create a high-energy plasma arc for the pyrolytic decomposition of feed materials. The vessel is configured with an upper portion and a lower portion, where the lower portion is for the containment of a layer of molten metal (iron) and a second layer of slag and having a substantially uniform width, while the upper portion being for the containment of gas and having a varying width. The reactor vessel comprises a steel shell housing a multi-layered wall that defines a chamber where the multi-layered wall includes a first layer high-density refractory material, a second intermediate layer of a insulating material, and a third outer layer of high-density refractory materials.

  • Patent number: 7993546
    Abstract: An apparatus for forming nano-structures of carbon solids includes a reactor chamber into which extends a plasma torch configured to generate a plasma plume that extends into the interior of the reactor chamber. CO2 from is applied to the plasma plume where the CO2 is dissociated into carbon and oxygen. A plurality of nozzles also extends into the reactor chamber, which sprays liquid water on the plume, cooling at least a portion of the carbon causing it to form solid carbon nano-structures in a mixture of liquid water. The mixture is conveyed to a flocculation tank.

  • Patent number: 7752983
    Abstract: A method and apparatus for plasma gasification of waste materials consisting of organic and inorganic portions is provided which includes a refractory-lined reactor vessel, a feeder mechanism, and a DC electrode device. The refractory-lined reactor vessel has a processing chamber formed therein. The feeder mechanism feeds continuously waste materials into the processing chamber at a controlled feed rate. The DC electrode device is used for heating the processing chamber to a sufficient temperature so as to convert the organic portions of the waste materials to a synthetic gas consisting of hydrogen and carbon monoxide and to a carbon particulate, and to convert the inorganic portions of the waste materials to a molten material consisting of a lower metallic layer and a slag layer formed on top of the metallic layer.

  • Patent number: 7743717
    Abstract: An apparatus for conveying solid waste to a furnace includes an opening to an elongated channel into which waste material is received and an outlet open to the furnace. A reciprocating ram with a head plate located in the channel opposite the outlet forces the waste toward the outlet. The ram also has an upper shield dimensioned to be slightly greater in area than the opening such that the opening is blocked when the ram is extended. The channel also includes an actuator-impelled restrictor plate for compressing waste as it is forced through said channel into a narrower portion, and a isolation door operable to close off the channel.

  • Patent number: 7582265
    Abstract: A gas conduit for venting high temperature reactor comprising a conduit portion in direct communication with the reactor for receiving gas therefrom where the conduit includes a Venturi for creating a high pressure zone in the area prior to exit of the reactor. The conduit, accordingly, has a portion having first and second diameters, where the second diameter less than the first diameter and is dimensioned in order to provide an area of high pressure in the region of the first diameter.

  • Publication number: 20090118561
    Abstract: A method for gasification of carbonic materials using CO2 is disclosed where materials having at least some carbon content are subjected to a high-temperature environment, for example, inside a reactor vessel in which a plasma are a plasma torch or the like is energized. CO2 is injected into such an environment in a substantially stoichiometric amount with respect to the amount of carbon within the carbonic components.
