Patent number: 10214694Abstract: This invention relates to a new process to directly produce transportation gasoline from synthesis gas containing principally carbon monoxide, carbon dioxide, and hydrogen. The process entails three sequential catalytic stages with intermediate heat exchange to provide the requisite temperature in each stage, but with no interstage separation. The recycle loop enhances the conversion of the synthesis gas to the desired products and also serves as heat sink for the highly exothermic reactions involved in each stage.Type: GrantFiled: May 23, 2017Date of Patent: February 26, 2019Assignee: Primus Green Energy Inc.Inventors: Howard L. Fang, Meifang Qin, Cunping Huang, Zhong He, Robert M. Koros

Publication number: 20180221842Abstract: The present invention relates to a multi-stage, single reactor and system for making methanol for synthesis gas (syngas). In particular, the reactor contains a shell and tube reactor that is divided at its top and bottom heads into a plurality vertical, isolated compartments. The associated compartments and tubes form a stage of the reactor. The raw syngas is fed to the first stage, and unreacted syngas from the first stage is fed to the second stage subsequent stages. Between each stage, the product, methanol and water, is removed from the reaction mixture before sending the unreacted syngas to the subsequent stage. The reactor allows for high conversion of synthesis gas to methanol in a once-through process, without requiring recycling of unreacted synthesis gas.Type: ApplicationFiled: August 9, 2016Publication date: August 9, 2018Inventors: Eli GAL, Robert M. KOROS, Benjamin MOSKOWITZ, Arnold KELLER

Patent number: 9169166Abstract: Synthetic fuels are produced from synthesis gas in a four-stage reactor system with a single recycle loop providing the requisite thermal capacity to moderate the high heat release of the reactions and to provide the reactants and reaction environments for the efficient operation of the process. The first reactor converts a portion of the synthesis gas to methanol; the second reactor converts the methanol to dimethylether; the third reactor converts the methanol and dimethylether to fuel; and the fourth reactor converts the high melting point component, durene, and other low volatility aromatic components such as tri- and tetra-methylbenzenes to high octane branched paraffins. A large part of the gas stream of the fourth reactor is recycled to the inlet of the first stage and mixed with the fresh synthesis gas stream. Alternatively, the fresh synthetic gas stream is mixed with the product of the second stage.Type: GrantFiled: January 15, 2014Date of Patent: October 27, 2015Assignee: Primus Green Energy Inc.Inventors: Howard L.

Patent number: 5403561Abstract: The uniform distribution of mixed phase fluid stream on to the top of a contact bed in a reactor chamber is provided by a horizontal tray with a plurality of spaced-apart, vertically disposed chimneys extending through the tray. These chimneys have a first end to receive liquid and gas above the tray and a second end for distributing the liquid and gas downwardly below the tray. Importantly, the second end is provided with a spray generating device located below the tray for producing a conical downward spray of the mixed fluid phase onto the top surface of a bed of contact material positioned below the tray. The spray generating devices for producing the conical spray are located at positions so that the spray of the mixed fluid stream from one spray generating device as it impinges on the top surface of the fixed bed, will overlap the spray from an adjacent spray generating device.Type: GrantFiled: August 27, 1993Date of Patent: April 4, 1995Assignee: Exxon Research & Engineering Co.Inventors: Robert M. Koros, Yiu W. Wong, John T. Wyatt, David C. Dankworth

Patent number: 5354990Abstract: The distribution of fluid flowing through a packed bed reactor is determined by placing a plurality of fiber optic sensors at desired locations within the packed bed reactor. A light analyzable tracer component is injected into the fluid flowing through the reactor. Light is supplied to each of the sensors causing any tracer component in the vicinity of the sensor to emit electromagnetic radiation. The emitted electromagnetic radiation is detected at each fiber optic sensor, thereby permitting the amount of tracer in the vicinity of each sensor to be determined, and consequently providing a measure of the distribution of fluid flowing through the reactor.Type: GrantFiled: May 18, 1993Date of Patent: October 11, 1994Assignee: Exxon Research and Engineering Co.Inventors: David C. Dankworth, Robert M. Koros
