Patent number: 7399408Abstract: A method and device for oxidization of materials in supercritical water. The method involves a) introducing a fluid containing water and an oxidizing agent in a ring-shaped area and through a first end of a substantially tube-shaped reactor comprising an external wall and an internal tube, b) heating the fluid in the ring-shaped area, c) introducing the heated fluid into the internal tube and simultaneously introducing material to be treated into said internal tube at a second end of the reactor, d) mixing the fluid and the material to be treated in a first portion of the internal tube, followed by cooling the obtained mixture in a second portion of the internal tube, and e) isobarically discharging the fluid/oxidized material from the internal tube of the reactor.Type: GrantFiled: November 19, 2004Date of Patent: July 15, 2008Assignee: Commissariat A l'Energie AtomiqueInventors: Christophe Joussot-Dubien, Gérard Didier, Hubert-Alexandre Turc

Publication number: 20080166265Abstract: The system is based on a recirculating Carbon Flow Loop, within which toxins in municipal waste or other feedstock are neutralized in a plasma reactor, by using an electric arc in ionized gas to generate ultra high temperatures. This breaks down substances into their basic molecules, and transforms the feedstock into syngas (which is comprised predominantly of hydrogen and carbon monoxide). This can be processed by a water shift reactor, an engine driven electric generator or another exothermic device where carbon monoxide is transformed into carbon dioxide. This continues flowing in the carbon loop to an Algae Bioreactor. Here photosynthesis of the algae transforms the carbon dioxide to become part of an oil rich carbohydrate. This can either continue to the next stage as feedstock and recirculate again around the Carbon Loop and/or exit, and be used to manufacture biofuel or other substances.Type: ApplicationFiled: January 10, 2007Publication date: July 10, 2008Inventor: Andrew Eric Day

Patent number: 7332095Abstract: An oxidation process is described which involves subjecting a feedstock which contains oxidizable material to temperature, pressure and contact with an oxidant. Excess water and volatile oxidation products, such as carbon dioxide, formic acid and acetic acid, are removed in the vapor phase. A catalyst may be employed to increase the rate of reaction. Preferred catalysts include the transition metal ions. Advantageously, the process may be operated in a continuous manner wherein the feedstock is continuously introduced into a reactor and a vapor phase containing volatile oxidation products continuously removed. The process is particularly applicable to the treatment of consumer and industrial waste.Type: GrantFiled: June 24, 2003Date of Patent: February 19, 2008Assignee: Victoria Link LimitedInventors: James Howard Johnston, Peter Thomas Northcote, Michael James Richardson

Patent number: 7211194Abstract: A gravity pressure vessel (GPV) for processing a fluid stream containing organic materials provides several improvements to the art. In one embodiment, a GPV of the present invention sustains the heat energy requirements of a hydrolysis GPV by including therein, a first reaction chamber for conducting an exothermic reaction, and subsequently providing a second reaction chamber for hydrolysis of certain organic materials refractory to the exothermic reaction. Another embodiment provides for the perpetual cleaning of the heat transfer surfaces of the GPV. Still another embodiment provides for selective alteration of a hydrolysis reaction within a GPV independent of the flow of the fluid stream through the GPV.Type: GrantFiled: October 27, 2004Date of Patent: May 1, 2007Assignee: Eau-Viron, Inc.Inventor: James A.

Patent number: 7196240Abstract: Methods and equipment are provided for making polybichlorophenyl non-toxic. Methods include a first oxidation step, in which polybichlorophenyl is burned, and a second oxidation step, in which exhaust gas from the first oxidation step is oxidized by contact with metallic phthalocyanines or metallic phthalocyanine derivatives and with an oxygen supply compound. Equipment includes a first furnace for burning a polybichlorophenyl-containing oil with an auxiliary fuel and a second oxidation reaction unit. The second oxidation reaction unit connects to the first furnace under seal, and includes metallic phthalocyanine or metallic phthalocyanine derivative solution supply source and an oxygen supply compound supply source.Type: GrantFiled: November 13, 2003Date of Patent: March 27, 2007Assignees: Ueda Textile Science FoundationInventors: Hirofusa Shirai, Mutsumi Kimura, Kenji Hanabusa, Kunihiro Hamada, Toshihiro Hirai

Patent number: 7169197Abstract: Solid waste resource recovery in space is effected by pyrolysis processing, to produce light gases as the main products (CH4, H2, CO2, CO, H2O, NH3) and a reactive carbon-rich char as the main byproduct. Significant amounts of liquid products are formed under less severe pyrolysis conditions, and are cracked almost completely to gases as the temperature is raised. A primary pyrolysis model for the composite mixture is based on an existing model for whole biomass materials, and an artificial neural network models the changes in gas composition with the severity of pyrolysis conditions.Type: GrantFiled: July 10, 2001Date of Patent: January 30, 2007Assignee: Advanced Fuel Research, Inc.Inventors: Michael A.

Patent number: 7141085Abstract: The refractory protected, replaceable insert for a gasifier includes a replaceable floor edge insert that is formed with a predetermined mating profile that is complementary to a finished mating profile of the gasifier floor. The geometry of the mating profiles of the replaceable floor edge insert and the gasifier floor permit removable engagement between the floor edge insert and the mating profile of the gasifier floor. The replaceable floor edge insert is protected by a ring-like arrangement of hanging refractory bricks that each include an appendage. Each brick appendage covers a portion of the inner radial edge of the replaceable floor edge insert and also covers an upper surface portion of an underlying quench ring, thus prolonging the life of the floor and the quench ring. A refractory ceramic fiber paper can be provided between the hanging brick and the floor edge and quench ring.Type: GrantFiled: January 16, 2003Date of Patent: November 28, 2006Assignees: Texaco Inc., Texaco Development CorporationInventors: John Corwyn Groen, John D.
