  • Patent number: 9908096
    Abstract: An energy conversion system includes a water-containing vessel with a transparent sidewall. Energized carbon rods are fed into the vessel such that the carbon rods are immersed in the water. The carbon rods are juxtaposed sufficiently that electrical arcing occurs between them, causing decomposition of some water molecules into constituent hydrogen and oxygen gas. Photon emissions resulting from the arcing are collected by photovoltaic cells placed around the sidewall of the vessel. The hydrogen gas is cooled by passing it through a water reservoir which also provides a source for water in the vessel. The cooled hydrogen gas may be used to fuel an internal combustion engine. Byproduct heat from the arcing reaction may be utilized in a Stirling engine or radiated from the system. As the carbon rods become depleted during arcing, additional rods are fed through conductive sleeves into the vessel by linear actuators.

Hydrocarbon material that is to be converted to syngas can be in gas, liquid and/or solid form including a slurry of very small powder particles. The hydrocarbons are subjected to very high levels of heat from one or more plasma torches in order to break the hydrocarbon chemical bonds. The residue from heating the hydrocarbon material drops into a pyrolysis unit quench section where the residue and molten ash are removed. Syngas that is extracted from the pyrolysis unit passes through syngas preparation processes that remove contaminants from the syngas. The syngas then passes through a syngas-to-liquid hydrocarbons process. Carbon dioxide that is removed from the syngas preparation and syngas-to-hydrocarbons processes is recycled to the pyrolysis unit.

    Abstract: A new and low cost method for producing single wall nanotubes and other allotropic forms of carbon. The method uses a high electric current and 127 VAC or 220 VAC power supplies to sublimation of a solid precursor, which material can be made of graphite. The solid precursor is connected to metallic electrodes, so that an intense electric current cross the contacts to pulverize the graphite under high temperature. The carbon materials are deposited in the wall of the reactor as well as in the electrodes, in an atmospheric pressure. The obtained material is purified in acids and, then, the carbon nanotubes are separated. In general, the synthesis is characterized by the absence of a metal catalyst, the employ of a short circuit current with an agent to produce carbon materials, the low pressure into reaction, and the assembly of the apparatus involving a low voltage of operation.

  • Publication number: 20130039816
    Abstract: A plasma reaction apparatus and method applied to reformation of fuel by generating and using rotating arc plasma in a furnace, the chemical treatment of a persistent gas, and the apparatus for decreasing NOx by an occlusion catalyst. A raw material for a reaction is allowed to flow into the furnace through a hole, causing it to flow within the furnace in a continuous swirl. Furthermore, an expanded plasma reaction zone is provided by a wide area chamber which is formed on an upper part of the furnace and has a greater width than that of a lower part of the furnace, and thus a plasma being generated can be expanded by the expanded plasma zone and delayed from flowing out of the furnace by corners of the wide area chamber that is spaced from a plasma inducing electrode therein.

  • Patent number: 8361404
    Abstract: A reactor for reforming a hydrocarbon, and associated processes and systems, are described herein. In one example, a reactor is provided that is configured to use non-equilibrium gliding are discharge plasma. In another example, the reactor uses a vortex flow pattern. Two stages of reforming are described. In a first stage, the hydrocarbon absorbs heat from the wall of the reactor and combusts to form carbon dioxide, carbon monoxide, and water. In a second stage, a gliding are discharge is use to form syngas, which is a mixture of hydrogen gas and carbon monoxide. The heat generated by the combustion of the first stage transfers to the wall of the reactor and heated products of the second stage mix with incoming hydrocarbon to provide for partial recuperation of the reaction energy.
