Patent number: 8038766Abstract: A direct reduction process for a metalliferous material includes supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidizing gas into a fluidized bed in a vessel and maintaining the fluidized bed in the vessel, at least partially reducing metalliferous material in the vessel, and discharging a product stream that includes the partially reduced metalliferous material from the vessel. The process comprises (a) reducing the metalliferous material in a solid state in a metal-rich zone in the vessel; (b) injecting the oxygen-containing gas into a carbon-rich zone in the vessel with a downward flow in a range of ±40° to the vertical and generating heat by reactions between oxygen and the metalliferous material (including metallized material), the solid carbonaceous material and other oxidizable solids and gases in the fluidized bed, and (c) transferring heat from the carbon-rich zone to the metal-rich zone by movement of solids within the vessel.Type: GrantFiled: May 20, 2005Date of Patent: October 18, 2011Assignee: Outotec OyjInventors: Andreas Orth, Heinz Eichberger, Donald Keith Philp, Jeantine Van Gemund, legal representative, Rod Dry

Publication number: 20110013662Abstract: A process for at least one of a chemical and a physical treatment of fluidizable substances in a reactor. The process includes introducing a hot gas into an interior of the reactor through a gas supply tube and cooling at least one of the hot gas and the gas supply tube with a coolant. The cooling is performed by contacting the hot gas with the coolant so as to provide a temperature of a wall of the gas supply tube at least 50° C. lower than a temperature of the gas at an inlet of the gas supply tube facing away from the interior of the reactor.Type: ApplicationFiled: August 28, 2008Publication date: January 20, 2011Applicant: OUTOTEC OYJInventors: Michael Missalla, Edgar Gasafi, Jean Claude Hein, Andreas Orth, Jean-Paul Nepper

Publication number: 20100313475Abstract: A process for refining raw materials containing oil and/or bitumen includes supplying the raw materials to a reactor. The reactor is operated under a pressure of from 0.001 to 1 bar and at a reactor temperature of from 300 to 1000° C. so as to volatize fuel gases and obtain solids and non-evaporated fractions of heavy hydrocarbons. The solids and non-evaporated fractions of heavy hydrocarbons are introduced into a furnace. The non-evaporated fractions of heavy hydrocarbons are burned in the furnace at a furnace temperature of from 600 to 1500° C. so as to obtain hot solids in the furnace. The hot solids are recirculated from the furnace into the reactor. An oxidizing atmosphere of the furnace is separated from an atmosphere of the reactor by a sealing device.Type: ApplicationFiled: February 4, 2009Publication date: December 16, 2010Applicant: OUTOTEC OYJInventors: Nikola Anastasijevic, Michael Missalla, Guenter Schneider, Andreas Orth
