Patent number: 8075644Abstract: A catalytic liquid fuel is described, including a liquid fuel added with at least one kind of catalytic ion or its salt to improve the oxidation activity thereof. The liquid fuel includes at least an organic liquid fuel or a reducing agent or their mixture. The oxidation activity of the fuel can be enhanced by adding an extremely low concentration of the catalytic ion or it salt. The catalytic liquid fuel also can overcome problems like low oxidation activity, surface poisoning and fading of catalysts.Type: GrantFiled: June 8, 2007Date of Patent: December 13, 2011Assignee: National Taiwan University of Science and TechnologyInventors: Bing-Joe Hwang, Jing-Shan Do, Shao-Kang Hu, Ching-Hsiang Chen, Kuo-Jung Wang, Sakkarapalayam Murugesan Senthil Kumar, Loka Subramanyam Sarma

Patent number: 6994774Abstract: The present invention provides a method and apparatus for maintaining the active life of a catalyst in organic feed processing by applying a series of electromagnetic radiation pulses to the catalyst in a reactor. The pulsing of the catalyst selectively heats and cools the catalyst and can regulate the relative internal pressure of the catalyst particles to stimulate the acceleration of oil macromolecules mass-exchange through the catalyst pores and surface. This allows for the removal of cracked oil molecules from the particles. The application of electromagnetic pulses also regulates the activity of the catalyst. The electromagnetic radiation reduces the formation of coke on the catalyst and increases the life of the catalyst in the reactor. Further, the present invention provides a method and apparatus for removing water and salt from an organic feed. Water and salt is removed by applying a series of electromagnetic radiation pulses to the organic feed.Type: GrantFiled: September 16, 2002Date of Patent: February 7, 2006Inventor: Serik M. Burkitbaev

Patent number: 6067914Abstract: A method of operating a combustion unit of a coal-fired power plant operating according to a slag tap furnace firing method, which includes supplying a titanium-containing material in addition to coal to a melting chamber for accelerating coal burn-up, burning the titanium-containing material together with the coal in the melting chamber at a temperature above 1500.degree. C., and generating fly ash and molten ash as a result of combustion in the melting chamber. Additionally, a combustion unit for a coal-fired power plant, including a melting chamber that has a combustion zone for receiving coal. The combustion zone produces fly ash.Type: GrantFiled: March 18, 1998Date of Patent: May 30, 2000Assignees: Siemens Aktiengesellschaft, STEAG AktiengesellschaftInventors: Erich Hums, Horst Spielmann, Ralf Gilgen

Patent number: 5186722Abstract: The invention relates to a process for providing fuels from biomass such as seed oils or plant fruits. Generally the process utilizes a metal catalyzed conversion to step to provide fuel mixtures with compositions that may be varied depending on conditions of temperature, pressure and time of reaction. Mixtures of hydrocarbons produced from limonene feedstocks include alicyclic, alkyl and aromatic species. Monocyclic aromatic compounds may be obtained in high yields depending on the reaction conditions employed.Type: GrantFiled: June 25, 1991Date of Patent: February 16, 1993Assignee: Cantrell Research, IncorporatedInventors: Charles L. Cantrell, Ngee S. Chong

Patent number: 4889538Abstract: An improved process is described for agglomeration beneficiation of ground coal in which undiluted heavy oil or bitumen is used as the agglomerating vehicle. The ground cell, water and heavy oil or bitumen are mixed at an elevated temperature sufficient to lower the viscosity of the heavy oil or bitumen to a level permitting easy mixing and at an elevated pressure sufficiently high to prevent boiling of the water. This mixing causes agglomeration of the carbonaceous solids with the heavy oil or bitumen and the agglomerates obtained are separated from the tailings containing aqueous medium and inorganic solids. The separated agglomerates are preferably used with additional heavy oil or bitumen to form a slurry feedstock for a coprocessing unit. This provides a very efficient total process since the coal agglomeration beneficiation uses a portion of the same heavy oil or bitumen feedstock which is used for coprocessing and no additional hydrocarbon diluent is required.Type: GrantFiled: July 14, 1988Date of Patent: December 26, 1989Assignee: Minister of Energy, Mines and Resources CanadaInventors: Josef A. Mikhlin, deceased, Michio Ikura, James F. Kelly, C. Edward Capes

Patent number: 4888029Abstract: A process for desulfurizing carbonaceous material containing inorganic bound sulfur, organic bound sulfur, or conbinations thereof. The process comprises reacting the carbonaceous material at desulfurization conditions with a hydrogen source material in the presence of a reaction accelerator to enhance production and reactivity of atomic hydrogen supplied by the hydrogen source. The reaction is prefereably carried out in the presence of a flowing reaction medium which carries away hydrogen sulfide products and other volatile desulfurization products separating them from the carbonaceous material.Type: GrantFiled: June 7, 1988Date of Patent: December 19, 1989Assignees: The Board of Trustees of Southern Illinois University, The Illinois State Geological SurveyInventors: Richard H. Shiley, Randall E. Hughes, John R. Webster, Conrad C. Hinckley, Gerald V. Smith, Tomasz Wiltowski

Patent number: 4828573Abstract: A method of manufacturing a pelletized fuel including the steps of hydrolizing cellulose containing material to form a binder, mixing the binder with combustible fines including preferably coal fines and wood chips or saw dust in which the binder is about two percent to eight percent by weight of the mixture, and forming the mixture into pellets. The pellets are dried by subjecting them to a temperature sufficient to drive off substantially the water content thereof to provide pellets which are crush resistant and weather resistant and which may thereby by handled for use as a fuel such as in a boiler for generating steam.Type: GrantFiled: April 13, 1987Date of Patent: May 9, 1989Assignee: Technology Research & Development, Inc.Inventor: James W. Jelks

Patent number: 4009384Abstract: A device for installing on an electric lamp to produce a pleasing scent. The device is in the form of a folded section of asbestos sheet, or other porous high temperature-resistant material, which encloses a sheet of porous fabric material which has been immersed in a solution of scented bath oil, perfume or cologne. A center hole in the device permits its installation on the frame of the shade of an electric lamp about the finial post of the lamp.Type: GrantFiled: March 10, 1975Date of Patent: February 22, 1977Assignee: The Raymond Lee Organization, Inc.Inventor: Ada R.
