Patent number: 9950975Abstract: The present technology is directed to processes involving formation of hydrocarbons and oxygenated hydrocarbons through use of oxygen supplied by ion transport membranes. More particularly, the present technology relates in part to a process involving steam reforming and subsequent production of a synthetic product where carbon dioxide and/or hydrogen downstream of the process is reclaimed to generate the synthetic product. The present technology also relates in part to an ethylene formation process involving a viral-templated coupling catalyst in the presence of an ion transport membrane.Type: GrantFiled: July 31, 2017Date of Patent: April 24, 2018Assignee: VELOCYS TECHNOLOGIES, LTD.Inventors: Andre Steynberg, Roy Lipski

Publication number: 20070142481Abstract: A process (10) for synthesising hydrocarbons includes feeding a gaseous feedstock (18) comprising hydrogen and carbon monoxide, into a first Fischer-Tropsch reaction stage (12) which is a three-phase low temperature catalytic Fischer-Tropsch reaction stage, and allowing the hydrogen and carbon monoxide partially to react catalytically in the first reaction stage (12) to form hydrocarbons. At least a portion of a tail gas (32) which includes unreacted hydrogen and carbon monoxide obtained from the first reaction stage, is fed into a second Fischer-Tropsch reaction stage (42) which is a two-phase high temperature catalytic Fischer-Tropsch reaction stage. The hydrogen and carbon monoxide are allowed at least partially to react catalytically in the second reaction stage (42) to form gaseous hydrocarbons.Type: ApplicationFiled: August 20, 2004Publication date: June 21, 2007Applicant: Sasol Technology (Proprietary) LimitedInventors: André Steynberg, Jacob De Boer, Herman Nel, Werner Ernst, Johannes Liebenberg

Publication number: 20060272986Abstract: Slurry phase apparatus is provided which includes a slurry vessel for holding a slurry comprising a liquid and solid particles and gas distribution means for injecting a gas into the slurry. The gas distribution means includes a sparger device which includes an apertured sparger portion inside the slurry vessel, an inlet portion leading into the slurry vessel and an outlet portion leading from the slurry vessel. The gas distribution means also includes closure means, external of the slurry vessel, and being operable to allow or deny flow from the sparger portion out through the outlet portion of the sparger device. The invention extends to a method of introducing or reintroducing a gas into a slurry vessel.Type: ApplicationFiled: August 10, 2006Publication date: December 7, 2006Applicant: SASOL Technology (Proprietary) LimitedInventor: Andre Steynberg

Publication number: 20060266674Abstract: A method is provided for introducing or reintroducing a gas into a slurry vessel holding a slurry comprising a liquid and solid particles and having a gas distributor for injecting a gas into the slurry, where the gas distributor includes a sparger device comprising an apertured sparger portion inside the slurry vessel, an inlet portion leading into the slurry vessel and an outlet portion leading from the slurry vessel, and a valve, external of the slurry vessel, operable to allow or deny flow from the sparger portion out through the outlet portion of the sparger device. The method comprises operating the valve to allow flow through the outlet portion of the sparger device, flushing the sparger device through the outlet portion to remove settled material which may be present in the sparger device, operating the valve to deny flow through the outlet portion of the sparger device, and introducing or reintroducing the gas into the slurry vessel through the sparger device.Type: ApplicationFiled: August 10, 2006Publication date: November 30, 2006Applicant: SASOL Technology (Proprietary) LimitedInventor: Andre Steynberg

Publication number: 20050027020Abstract: A process for starting up a Fischer-Tropsch reactor includes establishing, in the reactor, an initial charge of molten wax. The initial reactor temperature is below the line-out reactor temperature but is sufficiently high for a Fischer-Tropsch reaction to take place. The reactor contains, in contact with the molten wax, at least a portion of its line-out catalyst inventory. Syngas is fed into the reactor at an initial flow rate below the line-out syngas flow rate. Initially a syngas H2:CO molar ratio is maintained at a higher value than its line-out value, whereafter the syngas H2:CO molar ratio is decreased to its line-out value. The syngas flow rate and the reactor temperature are then increased to their line-out values.Type: ApplicationFiled: August 10, 2004Publication date: February 3, 2005Inventor: Andre Steynberg

Patent number: 6784212Abstract: A process for producing liquid hydrocarbon products includes converting a natural gas feedstock to synthesis gas, which is reacted, in a hydrocarbon synthesis stage and by a Fischer-Tropsch reaction, to produce a range of hydrocarbon product. An overheads vapour phase is separated from a liquid phase, and fed to a product condensation stage, where condensation of some components thereof takes place. A vapour phase, an aqueous phase, and a condensed product phase are withdrawn. The vapour phase is fed to a vapour phase work-up stage where a gas component comprising increased concentrations of CO and H2, relative to the vapour phase feed to the vapour phase work-up stage, is recovered, with this gas component being recycled to the hydrocarbon synthesis stage.Type: GrantFiled: June 24, 2002Date of Patent: August 31, 2004Assignee: Sasol Technology (Proprietary) LimitedInventors: Andre Steynberg, Simon Charles Clarke
