  • Patent number: 10808294
    Abstract: Scrap vehicles, mixtures of iron and aluminum, plastics are often pressed into bales or cubes to reduce the cost of transportation and storage to a smelter. Considering the dwindling number of large smelters in the United States due to the high pollution associated with coke fired cupolas, a new invention is developed to use natural gas, diesel fuels and clean fuels and hydrocarbons from scrap plastics in the bale. The process consists of three steps. In the first step the scrap bale is heated in a chamber up to temperatures of 1000° C. to promote the vaporization of zinc from galvanized steel, the pyrolysis of any plastics or scrap tires in the bale, and the separation of aluminum and magnesium by melting. The heat for this first stage is transferred through flue gases rising from the second and third stages after passing through a recuperator.

The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes.

  • Patent number: 7070634
    Abstract: A plasma reformer for the chemical reforming of gaseous mixtures of water and hydrocarbon fuels for producing hydrogen. The reformer contains a reaction chamber with outer lateral walls containing emitter electrodes and inner lateral walls containing collector electrodes. The emitter electrodes and collector electrodes form an electric circuit. There are a multiplicity of thin needle-like extrusions on the emitter electrode from which a profusion of high energy electrons are emitted. These high-energy electrons dissociate the hydrocarbon fuel through absorption and ionization emitting low energy electrons in the process. These low energy electrons cause dissociation of water. Thus, dissociation of hydrocarbon fuel acts to initiate dissociation of water. The molar ratio of water to hydrocarbon fuel in the input mixture for reactions, and therefor the production of hydrogen from water, increases with carbon number of the hydrocarbon fuel.

  • Patent number: 4472245
    Abstract: Materials which become carbonized at high temperatures, such as wood, cellulose, household refuse, used tires, plastics, tar sand, oil shale, and the like, are subjected to thermal treatment, i.e., pyrolysis or gasification, in an electric shaft furnace having top and bottom electrodes. The material is charged into the furnace at the top and continuously moved downward through the furnace so slowly that as a result of heat transfer from the hotter parts of the furnace, it is carbonized to an extent which renders it electrically conductive by the time it comes in contact with those parts of the electrodes by means of which electric current is conducted through the material. The material charged at the top of the furnace can be caused to move downward by withdrawing suitable amounts of solid material from the bottom of the furnace, for example, or by gasifying the material with steam.

  • Patent number: 4141694
    Abstract: An apparatus for gasification of carbonaceous matter by plasma arc pyrolysis is disclosed. In one embodiment, a refractory-lined furnace is provided with a depression along its base for holding a pool of molten metal which acts as the external electrode for a bank of long arc column plasma torches which provide a heat mass for the process. The plasma arc pressure imparts momentum to the surface of the melt and causes it to flow in cusping eddy currents during the process. Crushed coal is deposited through the roof of the furnace by a rotary feeder in continuous plural streams. The coal is devolatilized in a matter of milliseconds and the volatiles are cracked as the coal falls by gravity through the interior of the furnace. The remaining carbon-rich char collects at plural sites on the surface of the melt and the mounds of char are rotated by the eddy currents. Steam is continuously injected into the furnace to produce hydrocarbon gases through reaction with the carbon-rich char.
