This feed is injected by injectors 4 into the empty reactor 10 (i.e., without catalyst.) The feed is treated with a jet of gas or superheated steam from superheater 2 to activate the feed. The activated products in the feed are allowed to stabilize at the selected temperature and at a selected pressure in the reactor and are then run through a series of extractors 13 to separate heavy and light hydrocarbons and to demetallize the feed. Useful products appearing in the form of water/hydrogen emulsions are generally demulsified in emulsion breaker 16 to form water laden with different impurities.Type: GrantFiled: May 2, 2003Date of Patent: January 24, 2006Assignee: World Energy Systems CorporationInventor: Pierre Jorgensen

Publication number: 20040108251Abstract: A method for processing carbonaceous material in a reactor. Carbonaceous material, such as sawdust, plant residues from forestry or agricultural processes, municipal solid waste and refuse derived fuel, is fed into the riser section (10) of a reactor (10-15) in which it is contacted with inorganic particulate material and reactor walls at an elevated temperature essentially in the absence of oxygen in order to convert the carbonaceous material at least mainly into gaseous processed products, whereby a gas phase is obtained, containing fluidization gas and processed products. According to the invention a dense suspension is formed into the riser space (10) of the reactor, containing based on the particle number 7×108 to 3×1011 particles/m3 (about 2×107-1×1010 particles/ft3), and the mass ratio between the particulate matter bringing heat into the reactor and the carbonaceous material is in the range of 1:1 to 10:1.Type: ApplicationFiled: October 10, 2003Publication date: June 10, 2004Inventors: Steven Gust, Jukka-Pekka Nieminen, Jyrki Hiltunen, Pekka Knuuttila, Marko Fabritius, Pekka Jokela, Jatta Partanen

Patent number: 6652736Abstract: The invention concerns a stripping method for extracting solid fluidized particles whereby the particles to be stripped are subjected to a first stripping in a first chamber (9), then at least a second stripping in a second chamber (10) wherein are provided solid/gas separating means allowing the gaseous fluids derived from the second stripping to directly pass through from the bottom to the top but preventing them from going up again into the first chamber (9). The invention also concerns a device for implementing said method.Type: GrantFiled: April 23, 2001Date of Patent: November 25, 2003Assignee: Total Raffinage Distribution S.A.Inventors: Mariano Del Pozo, Tanneguy Descazeaud, Daniel Barthod

Publication number: 20030167691Abstract: This invention discloses improvements on previous inventions for catalytic conversion of coal and steam to methane. The disclosed improvements permit conversion of petroleum residua or heavy crude petroleum to methane and carbon dioxide such that nearly all of the heating value of the converted hydrocarbons is recovered as heating value of the product methane. The liquid feed is distributed over a fluidized solid particulate catalyst containing alkali metal and carbon as petroleum coke at elevated temperature and pressure from the lower stage and transported to the upper stage of a two-stage reactor. Particulate solids containing carbon and alkali metal are circulated between the two stages. Superheated steam and recycled hydrogen and carbon monoxide are fed to the lower stage, fluidizing the particulate solids and gasifying some of the carbon. The gas phase from the lower stage passes through the upper stage, completing the reaction of the gas phase.Type: ApplicationFiled: March 5, 2002Publication date: September 11, 2003Inventor: Nicholas Charles Nahas

Patent number: 5681450Abstract: A cyclone and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added around a clean gas outlet tube in a cyclone body. Solids and some gas are withdrawn via a solids outlet and discharged into a catch chamber. Some of the gas discharged with the solids into the catch chamber is returned to the interior of the cyclone body via an opening in the cyclone. Chaotic reflux of gas back into the cyclone via the solids outlet is eliminated. The device may be used as an FCC regenerator third stage separator or to improve other gas/solid separations.Type: GrantFiled: June 7, 1995Date of Patent: October 28, 1997Inventors: Girish K. Chitnis, Stephen J. McGovern, Klaus W. Schatz

Patent number: 5219530Abstract: Apparatus for initiating pyrolysis of a feedstock by establishing a continuous, standing shock wave. Several embodiments of a shock wave reactor (10, 100, 150) are disclosed; each is connected to receive an ethane feedstock and a carrier fluid comprising superheated steam. The feedstock and the carrier fluid are pressurized so that they expand into parallel supersonic streams that mix due to turbulence within a mixing section (36) of a longitudinally extending channel (12) of the shock wave reactor. The carrier fluid heats the ethane feedstock as it mixes with it, producing a mixture that flows at supersonic velocity longitudinally down the channel. A gate valve (44) disposed downstream of the channel provides a controlled back pressure that affects the position of the shock wave and the residence time for the reaction. The shock wave rapidly heats the mixture above a pyrolysis temperature, producing a desired product by cracking the feedstock.Type: GrantFiled: February 15, 1991Date of Patent: June 15, 1993Assignee: Board of Regents of the University of WashingtonInventors: Abraham Hertzberg, Arthur T.
