Oil Gas Patents (Class 48/84)
  • Patent number: 8388708
    Abstract: A process and device for the material utilization of soot from the waste water of a gasification appliance (heavy oil POX) in which a hydrogen- and carbon monoxide-containing (crude synthesis gas) is generated from relatively high-boiling hydrocarbons by partial oxidation, is disclosed. The soot-loaded waste water from the heavy oil POX is mixed with naphtha and is subsequently introduced into a separator (decanter) from which a substantially soot-free water fraction and a substantially water-free naphtha/soot mixture are taken off separately, where the naphtha/soot mixture is fed as feed to a further gasification appliance (naphtha POX), in which appliance predominantly naphtha is converted into a crude synthesis gas by partial oxidation.

  • Patent number: 8038960
    Abstract: A reformer that produces reformed gas from a hydrocarbon material includes a reforming chamber having an inner cylinder and an outer cylinder; a reforming catalyst filled in the reforming chamber; a burner that heats the reforming catalyst and fuel of reformed gas; a combustion gas outer flow channel through which combustion gas of the burner flows along an outer side surface of the reforming chamber; a combustion gas inner flow channel through which the combustion gas of the burner flows along an inner side surface of the reforming chamber; and a plurality of return pipes as a reformed gas flow channel.

  • Patent number: 7867301
    Abstract: A pre-reformer comprises a non-electrically conducting gas tight duct and an electrically conducting wire arranged in the duct. The electrically conducting wire is electrically isolated from the duct. The duct has an inlet for receiving a hydrocarbon fuel at a first end and an outlet for supplying a pre-reformed hydrocarbon fuel at a second end. At least the inner surface of the duct is chemically inert with respect to the hydrocarbon fuel. An electrical power supply is electrically connected to the electrically conducting wire and a control means controls the supply of electrical current through the electrically conducting wire to provide thermal decomposition of higher hydrocarbons in the hydrocarbon fuel. The performer reduces coking in associated fuel cells and other parts of a fuel cell system.

  • Patent number: 7776113
    Abstract: The reaction of carbon monoxide with steam over an alkali-modified ruthenium-on-zirconia catalyst has been found to yield surprisingly high yields of hydrogen gas at relatively low temperatures. Catalyst structures, reactors, hydrogen production systems, and methods for producing hydrogen utilizing the alkali-modified ruthenium-on-zirconia catalyst are described. Methods of making catalysts are also described.

  • Patent number: 7318845
    Abstract: A distillate fuel steam reformer system in which a fuel feed stream is first separated into two process streams: an aliphatics-rich, sulfur-depleted gas stream, and an aromatics- and sulfur-rich liquid residue stream. The aliphatics-rich gas stream is desulfurized, mixed with steam, and converted in a reforming reactor to a hydrogen-rich product stream. The aromatics-rich residue stream is mixed with air and combusted to provide heat necessary for endothermic process operations. Reducing the amounts of sulfur and aromatic hydrocarbons directed to desulfurzation and reforming operations minimizes the size and weight of the overall apparatus. The process of the invention is well suited to the use of microchannel apparatuses for heat exchangers, reactors, and other system components, which may be assembled in slab configuration, further reducing system size and weight.

  • Patent number: 7037473
    Abstract: An appliance for the gasification of carbon- and ash-containing fuel, residual and waste materials using an oxygen-containing oxidizing agent at temperatures above the melting point of the inorganic fractions, in a reaction chamber which is designed as an entrained-bed reactor, at pressures between atmospheric pressure and 80 bar, preferably between atmospheric pressure and 30 bar, the contour of the reaction chamber being delimited by a cooled reactor wall. The cooled reactor wall having the following structure, from the outside inward: a pressure shell, a cooling wall, a water-cooled gap between the pressure shell and the cooling wall, a ceramic protection for the cooling wall, and a layer of slag. The pressure and temperature of the cooling gap between the pressure shell and the cooling wall is controlled in such a way that it can be operated above and below the boiling point of the cooling water. The pressure in the cooling gap is higher than the pressure in the gasification chamber.

  • Patent number: 6437769
    Abstract: A display apparatus having a structure in which planar multicolor light sources (201, 202, 203, and 204), such as ELs, are used as multicolor light sources, and a planar optical modulation panel (210) is combined therewith. In contrast with a construction in which a multicolor cold-cathode tube and a light valve are driven by time division, the outer shape of the display apparatus can be reduced, power consumption is reduced, and excellent color display can be performed.
