Patent number: 7713490Abstract: A process is disclosed for providing a flow of particulate matter such as a catalyst to a reactor, comprising intermittently adding said particulate matter and a diluent to a mixing tank, and continuously withdrawing a slurry of particulate matter in diluent from the mixing tank for introduction into the reactor, wherein prior to each addition of particulate matter and diluent to the mixing tank, the concentration of particulate matter in the diluent already in the mixing tank is measured or calculated, and the amount of particulate matter and diluent subsequently added is measured so as to achieve the same concentration at the end of the addition as that measured or calculated prior to the addition. Preferably measurement of the amount of particulate mailer and diluent added to the mixing tank is carried out before any diluent is added to the particulate matter.Type: GrantFiled: December 5, 2003Date of Patent: May 11, 2010Assignee: Ineos Manufacturing Belgium NVInventor: Brent Walworth

Publication number: 20100111786Abstract: Use of a high shear mechanical device in a process for production of starch by hydration and disruption of corn kernel particles in the presence of sulfur dioxide or bisulfite ions makes possible a decrease in mass transfer limitations, thereby enhancing starch production. A system for production of starch is also provided in which a high shear mixing device is configured to receive an aqueous corn slurry from a pump that is disposed between the reactor and a gaseous sulfur dioxide inlet of the high shear mixing device. The high shear mixing device is also configured to generate a fine dispersion of sulfur dioxide bubbles and small corn particles in the slurry. A reactor is configured to receive the output from the high shear mixing device and to provide for starch production.Type: ApplicationFiled: July 31, 2009Publication date: May 6, 2010Applicant: H R D CORPORATIONInventors: Abbas Hassan, Ebrahim Bagherzadeh, Rayford G.

Patent number: 7708897Abstract: Device, system and method for injecting organic matter into a reaction enclosure (2) of a reactor for treatment using a supercritical water oxidation method. The device comprises a body having an inner volume defining a pressurizing capacity (24) in which a mobile assembly (29) is arranged, e.g. a bellows for dividing the inner volume into two variable volume compartments including a compressing capacity compartment (32) and a hydraulic pressurizing capacity compartment (34). The hydraulic pressurizing capacity compartment is preferably connected to the outlet (15) of an aqueous phase liquid/gas separator (14) which separates the liquid and gaseous phases of the effluent leaving the reaction enclosure (2).Type: GrantFiled: August 16, 2005Date of Patent: May 4, 2010Assignee: Commissariat A l'Energie AtomiqueInventors: Christophe Joussot-Dubien, Hubert-Alexandre Turc

Patent number: 7704466Abstract: A self-propagating combustion cyclone reactor includes a reaction chamber delimited by a circumferential wall in which at least one reductant inlet and a plurality of oxidizer inlets are formed in a tangential manner. Reductant and oxidizer are fed, together with inert gas, through the inlets into the chamber in a cyclonic manner to induce self-propagating combustion reaction to generate a product of high purity metal, such as titanium, zirconium, hafnium, or silicon, semiconductor substance. The reactor serves as a continuous reactor for generation of metal or semiconductor substances of high purity.Type: GrantFiled: November 14, 2007Date of Patent: April 27, 2010Assignee: Sun Materials Technology Co., Ltd.Inventor: Yi-Shuen Wu

Publication number: 20100056774Abstract: A method is provided for hydrolyzing polysaccharides in a lignocellulosic feedstock to produce monosaccharides or pretreating a lignocellulosic feedstock, in which an aqueous slurry of the lignocellulosic feedstock is fed into a pressurized dewatering zone wherein the feedstock is partially dewatered and then is compressed into a plug. The plug is introduced into a reaction zone that operates at a pressure (Pr) equal to greater than about 90 psia and under suitable temperature and pH conditions to hydrolyze the polysaccharides or pretreat the feedstock. The plug provides a pressure seal between the outlet of the dewatering zone and the reaction zone. The pressure (Pdwi) of the aqueous slurry of the lignocellulosic feedstock at the inlet of the dewatering device is related to Pr as follows: 0??P<the lesser of [(Pr?20 psia) and 220 psia], and where ?P is the absolute difference in pressure between Pr and Pdwi in psia.Type: ApplicationFiled: August 27, 2009Publication date: March 4, 2010Applicant: IOGEN ENERGY CORPORATIONInventors: Vijay Kumar Anand, Stephen Rowland, Patrick Foody, SR.

Publication number: 20090304558Abstract: An apparatus, system, and method are disclosed for generating a gas. One or more liquid permeable pouches each define a cavity that contains a solid anhydrous reactant, such as a chemical hydride. A reaction chamber made of a heat, chemical and/or pressure resistant material receives the one or more pouches from a pouch feeder that transfers the one or more pouches into the reaction chamber successively at a feed rate. One or more liquid sources inject a liquid reactant into the reaction chamber so that the liquid reactant contacts a portion of the one or more pouches. The one or more liquid sources inject the liquid reactant at an injection rate that corresponds to the feed rate. A gas outlet releases a gas, such as hydrogen, oxygen, ammonia, borazine, nitrogen, or a hydrocarbon, that is produced by a reaction between the solid reactant and the liquid reactant.Type: ApplicationFiled: June 8, 2009Publication date: December 10, 2009Inventors: John Madison Patton, Howard Anderson
