Publication number: 20240075447Abstract: A device may include a plasma chamber in fluid communication with an ancillary reaction chamber and an integrated reformer. The integrated reformer may be in fluid communication with the ancillary reaction chamber. The ancillary reaction chamber may be configured to utilize heat from a heated first synthesis gas stream received from the plasma chamber to initiate an exothermic reaction with a second gas stream to output a heated second synthesis gas stream to the integrated reformer.Type: ApplicationFiled: September 7, 2023Publication date: March 7, 2024Applicant: RECARBON, INC.Inventors: Hatem Harraz, Jae Mo Koo, Hee Seon Kim

Publication number: 20230226515Abstract: An integrated reformer includes an outer chamber, a first inlet, a second inlet, and a cooling unit associated with the outer chamber. The first inlet is configured to obtain a first gas stream into a first space in the outer chamber. The second inlet is configured to obtain a second gas stream into the first space in the outer chamber. The cooling unit is configured to absorb thermal energy from the first gas stream.Type: ApplicationFiled: January 13, 2023Publication date: July 20, 2023Inventors: Hatem Harraz, Jae Mo Koo

Patent number: 9701597Abstract: The present disclosure provides oxidative coupling of methane (OCM) systems for small scale and world scale production of olefins. An OCM system may comprise an OCM subsystem that generates a product stream comprising C2+ compounds and non-C2+ impurities from methane and an oxidizing agent. At least one separations subsystem downstream of, and fluidically coupled to, the OCM subsystem can be used to separate the non-C2+ impurities from the C2+ compounds. A methanation subsystem downstream and fluidically coupled to the OCM subsystem can be used to react H2 with CO and/or CO2 in the non-C2+ impurities to generate methane, which can be recycled to the OCM subsystem. The OCM system can be integrated in a non-OCM system, such as a natural gas liquids system or an existing ethylene cracker.Type: GrantFiled: January 8, 2015Date of Patent: July 11, 2017Assignee: Siluria Technologies, Inc.Inventors: Humera A. Rafique, Srinivas Vuddagiri, Hatem Harraz, Guido Radaelli, Erik C. Scher, Jarod McCormick, Rahul Iyer, Suchia Duggal, Joel Cizeron, Jin Ki Hong

Publication number: 20050272926Abstract: A non crystalline or low crystallinity cellulose. A method of making a non crystalline or low crystallinity cellulose comprising providing cellulosic material, adding an effective acid in an amount effective to at least wet the cellulosic material, mixing the cellulosic material and acid under conditions effective to form an essentially uniformly wet condition, letting the mixture sit at ambient conditions for a period of time sufficient to form a viscous fluid, adding water or other diluent in an amount sufficient to lower the acid concentration and to form a slurry, dewatering the slurry, and removing any residual acid from the dewatered slurry.Type: ApplicationFiled: June 2, 2005Publication date: December 8, 2005Inventors: Yoon Lee, Hatem Harraz
