Patent number: 7541504Abstract: The invention relates to methods for improving the octane number of a synthetic naphtha stream and optionally for producing olefins and/or solvents. In one embodiment, the method comprises aromatizing at least a portion of a synthetic naphtha stream to produce an aromatized hydrocarbon stream; and isomerizing at least a portion of the aromatized hydrocarbon stream to produce an isomerized aromatized hydrocarbon stream having a higher octane rating than the synthetic naphtha stream. Alternatively, the method comprises providing at least three synthetic naphtha cuts comprising a C4-C5 stream; a C6-C8 stream and a C9-C11 stream; aromatizing some of the C6-C8 stream to form an aromatized hydrocarbon stream with a higher octane number; steam cracking some of the C6-C8 stream and optionally the C9-C11 stream to form olefins; and selling some portions of C9-C11 stream as solvents. In preferred embodiments, the synthetic naphtha is derived from Fischer-Tropsch synthesis.Type: GrantFiled: February 3, 2005Date of Patent: June 2, 2009Assignee: ConocoPhillips CompanyInventors: Priya Rangarajan, Steven R. McDonald, Joe D. Allison, Keith H. Lawson, Oluwaseyi A. Odueyungbo, Doug S. Jack, Rafael L. Espinoza

Patent number: 7183327Abstract: A method for selecting maximum and minimum catalyst particle sizes for use in a multiphase reactor that reflects optimum operating conditions of the reactor is based on a maximum Archimedes number for estimating the maximum particle size and a property of a separation system linked to the reactor to determine the minimum particle size. The maximum Archimedes number could be selected based on a maximum catalyst non-uniformity in the reactor. Additionally, a method for producing hydrocarbons from syngas in a slurry bubble column reactor comprises the use of a plurality of fresh catalyst particles with an optimum size distribution based on a range of Archimedes numbers between about 0.02 and 250 or alternatively based on an average Reynolds number less than about 0.1.Type: GrantFiled: March 18, 2004Date of Patent: February 27, 2007Assignee: ConocoPhillips CompanyInventors: Rafael L. Espinoza, Oluwaseyi A. Odueyungbo, Jianping Zhang, Sergio R. Mohedas

Patent number: 7078439Abstract: This invention relates to methods and apparatus for separating liquid products and catalyst particles from a slurry used in a Fischer-Tropsch reactor system. The preferred embodiments of the present invention are characterized by a separation system that uses a sedimentation chamber, which contains at least one inclined channel that enhances the settling of particles within the slurry. The enhanced settling separates the slurry into a catalyst-rich bottom stream and a catalyst-lean overhead stream. The catalyst-rich bottom product stream is preferably recycled to the reactor, while the catalyst-lean overhead stream can be further processed by a secondary separation system to produce valuable synthetic fuels. The inclined channel may be provided by a structure selected from the group consisting of tube, pipe, conduit, sheets, trays, walls, plates, and combinations thereof.Type: GrantFiled: January 7, 2004Date of Patent: July 18, 2006Assignee: ConocoPhillips CompanyInventors: Oluwaseyi A. Odueyungbo, Rafael L. Espinoza, Sergio R. Mohedas, James Dale Ortego, Jr., Beatrice C. Ortego, Ralph T. Goodwin, Todd H. Harkins

Publication number: 20060054865Abstract: The invention includes a denatured liquid and a method for making the same. In one embodiment, the method comprises feeding a syngas to a hydrocarbon synthesis reactor, wherein the syngas is reacted to produce a hydrocarbon synthesis product. A naphtha is produced from the hydrocarbon synthesis product and combined with a liquid to denature the liquid. In other embodiments, the denatured liquid comprises ethanol.Type: ApplicationFiled: September 14, 2004Publication date: March 16, 2006Applicant: ConocoPhillips CompanyInventors: Douglas Smith, Keith Lawson, Priya Rangarajan, Oluwaseyi Odueyungbo

Patent number: 6929754Abstract: Methods and apparatus for removing wax products from a slurry used in a Fischer-Tropsch reactor. The preferred embodiments of the present invention are characterized by a solid/liquid separation system that removes liquid products from a slurry by drawing the fluid across a filter medium composed of a filter cake disposed on a substrate. In the preferred embodiments, the filter cake is desirable and performs the majority of the filtration. In certain embodiments, the filter medium is disposed in a filter housing where slurry flows parallel to the longitudinal axis of the filter medium from and inlet to an outlet. The characteristics or properties of the cake, which will effect the performance of the solid/liquid separation system, can be controlled by regulating the velocity of the slurry flowing across the cake, where the velocity may be regulated by adjusting the slurry flow through the filter housing or may be self-regulated by changing slurry velocities influenced by the design of the filter housing.Type: GrantFiled: April 16, 2003Date of Patent: August 16, 2005Assignee: ConocoPhillips CompanyInventors: Rafael L. Espinoza, Sergio R. Mohedas, Doug S. Jack, Oluwaseyi A. Odueyungbo, James Dale Ortego, Jr.
