Patent number: 8258195Abstract: A method is disclosed for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products. A synthesis gas including carbon monoxide and hydrogen gas is provided to a F-T reactor. Also, acetylene is supplied to the F-T reactor. The ratio of the volume of acetylene to the volume of synthesis gas is at least 0.01. The synthesis gas and acetylene are reacted under suitable reaction conditions and in the presence of a catalyst to produce F-T hydrocarbon products. The F-T hydrocarbon products are then recovered from the reactor. The synthesis gas and acetylene may be provided in a combined feed stream or introduced separately into the reactor. The acetylene enhanced syngas conversion in a F-T reactor results in the synthesis of F-T products which have a tighter distribution of intermediate length carbon products than do F-T products synthesized according to conventional methods.Type: GrantFiled: March 15, 2012Date of Patent: September 4, 2012Assignees: Chevron U.S.A.

Patent number: 6849774Abstract: Methods for separating di-olefins from mono-olefins, and olefins from non-olefins such as paraffins, oxygenates and aromatics; are provided. The methods use metal salts which complex both mono-olefins and di-olefins, but which selectively complex di-olefins in the presence of mono-olefins. The metal salts are dissolved or suspended in ionic liquids, which tend to have virtually no vapor pressure. Preferred salts are Group IB salts, more preferably silver and copper salts. A preferred silver salt is silver tetrafluoroborate. A preferred copper salt is silver CuOTf. Preferred ionic liquids are those which form stable solutions, suspensions or dispersions of the metal salts, which do not dissolve unwanted non-olefins, and which do not isomerize the mono- or di-olefins. The equivalents of the metal salt can be adjusted so that di-olefins are selectively adsorbed from mixtures of mono- and di-olefins. Alternatively, both mono- and di-olefins can be adsorbed, and the mono-olefins selectively desorbed.Type: GrantFiled: December 31, 2001Date of Patent: February 1, 2005Assignee: Chevron U.S.A.

Patent number: 6623659Abstract: Methods for separating olefins from non-olefins, such as paraffins, including cycloparaffins, oxygenates and aromatics, are provided. The methods use metal salts to complex olefins, allowing the non-olefins to be separated by a variety of methods, including decantation and distillation. The metal salts are dissolved in ionic liquids, which tend to have virtually no vapor pressure, and which poorly solubilize the non-olefins. Accordingly, the non-olefins phase separate well, and can be distilled without carrying over any of the ionic liquid into the distillate. Preferred salts are Group IB salts, more preferably silver salts. A preferred silver salt is silver tetrafluoroborate. Preferred ionic liquids are those which form stable solutions or dispersions of the metal salts, and which do not dissolve the non-olefins. Further, if the olefins are subject to isomerization, the ionic liquid is preferably relatively non-acidic.Type: GrantFiled: December 3, 2001Date of Patent: September 23, 2003Assignee: Chevron U.S.A. Inc.Inventors: Curtis L. Munson, Laura C. Boudreau, Michael S. Driver, William L. Schinski

Publication number: 20030150776Abstract: A process for increasing the yield of C10 plus hydrocarbon products from a Fischer-Tropsch plant which comprises the steps of (a) separating a Fischer-Tropsch product into a wax fraction and a condensate fraction; (b) dewaxing the wax fraction to produce a high boiling intermediate; (c) hydrofinishing the high boiling intermediate; (d) dehydrating the alcohols in the condensate fraction to convert them into olefins; (e) oligomerizing the olefins to form higher molecular weight hydrocarbons; (f) hydrofinishing the oligomerization mixture; and (g) and recovering a C10 plus hydrocarbon product from the hydrofinishing zone.Type: ApplicationFiled: February 8, 2002Publication date: August 14, 2003Inventors: David R.
