Patent number: 9169169Abstract: A process for the oligomerization of olefins includes treating, e.g., water washing, an olefin-containing hydrocarbon stream to lower the concentration of an organic nitrogen-containing Lewis base contained therein until the treated hydrocarbon stream is substantially free of the Lewis base; and subsequently contacting the treated hydrocarbon stream with a molecular sieve catalyst to produce a product including at least one oligomer.Type: GrantFiled: June 24, 2011Date of Patent: October 27, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: John Stephen Godsmark, George Marie Karel Mathys, Hubertus Joseph Beckers, Charles Morris Yarbrough, Stephen Harold Brown, Yeo-Meng Lim

Publication number: 20110282092Abstract: Nitrogen-containing Lewis bases act as poisons for molecular sieve catalysts used in oligomerisation reactions. Lowering their presence in the feed prior to the contacting thereof with the molecular sieve brings a significant extension of catalyst life. Thus, processes that are directed to the lowering of these poisons are provided.Type: ApplicationFiled: June 24, 2011Publication date: November 17, 2011Inventors: John Stephen Godsmark, George Marie Karel Mathys, Hubertus Joseph Beckers, Charles Morris Yarbrough, Stephen Harold Brown, Yeo-Meng Lim

Patent number: 7989668Abstract: Nitrogen-containing Lewis bases act as poisons for molecular sieve catalysts used in oligomerisation reactions. A lowering of their presence in the feed prior to the contacting thereof with the molecular sieve brings a significant extension of catalyst life. Excessive elimination of these poisons may be disadvantageous. Lowering the levels of these catalyst poisons to more manageable concentrations is therefore preferred.Type: GrantFiled: February 1, 2007Date of Patent: August 2, 2011Assignee: Exxonmobil Chemical Patents Inc.Inventors: John Stephen Godsmark, Georges Marie Karel Mathys, Hubertus Joseph Beckers, Charles Morris Yarbrough, Stephen Harold Brown, Yeo-Meng Lim

Patent number: 7910782Abstract: In a hydroformylation reaction, the circulation and recovery of cobalt carbonyl in a cobalt catalyst cycle using carbonylate as an intermediate and acidification thereof, is improved by supplying an aqueous sulfuric acid solution containing less than 16% wt of sulfuric acid to the carbonylate to control sulfuric acid concentration in the carbonylate/acid mixture, before accounting for any acid consuming reaction, to a value of from 2% to 10% by weight. Single step and multistage liquid/liquid extraction techniques as well as vapor/liquid extraction techniques followed by the absorption of cobalt from the vapor in an organic liquid both benefit from this improvement.Type: GrantFiled: March 28, 2008Date of Patent: March 22, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: Eddy T. A. Van Driessche, Arie Van Vliet, Raphael Frans Caers, Hubertus Joseph Beckers, Ronald Dean Garton, Bertrand Raymond Da Cruz, Michel J. P. Lepagnol, Edwin Kooke

Patent number: 7582802Abstract: Propylene streams obtained by the conversion of oxygenates to olefins are used as feeds for hydroformylation. The streams may contain measurable amounts of dimethyl ether without adversely impacting the hydroformylation.Type: GrantFiled: January 28, 2005Date of Patent: September 1, 2009Assignee: ExxonMobil Chemical Patents Inc.Inventors: Raphael Frans Caers, Hubertus Joseph Beckers, Eddy Theophyle Andrea Van Driessche, Luc Roger Marc Martens, John Stephen Godsmark, John Richard Shutt

Patent number: 7405329Abstract: The gas cycle in a high pressure hydroformylation reaction using a series of at least two reactors is controlled to optimise yield, conversion and selectivity and to control reaction temperature. The control is achieved through balancing fresh gases and recycle gases in each of the reactors and as an optional feature the use of hydrogen off gases from the downstream hydrogenation used in the conversion of the hydroformylation reaction product to product alcohols.Type: GrantFiled: December 16, 2004Date of Patent: July 29, 2008Assignee: ExxonMobil Chemical Patents Inc.Inventors: Stephen Wayne Beadle, Ronald Dean Garton, Hubertus Joseph Beckers, Raphael Frans Caers, Arie Van Vliet, John J. Houben

Patent number: 7238844Abstract: This invention is to a method of oligomerizing an olefin feed stream. The olefin feed stream contains at least one C2 to C12 olefin to obtain an olefin feed stream and has less than 1,000 ppm by weight oxygenated hydrocarbon. The olefin is oligomerized by contacting with an acid based oligomerization catalyst.Type: GrantFiled: March 22, 2004Date of Patent: July 3, 2007Assignee: ExxonMobil Chemical Patents Inc.Inventors: Georges M. K. Mathys, Stephen H. Brown, Hubertus Joseph Beckers, Raphael Frans Caers, John Stephen Godsmark, Luc R. M. Martens, John Richard Shutt, Eddy T. Van Driessche
