Patent number: 7314545Abstract: This invention is a method of purifying fuels containing organosulfur impurities. The fuel is oxidized with an organic hydroperoxide in the presence of an oxidation catalyst to form a sulfone product, followed by extraction of the sulfone product by solid-liquid or liquid-liquid extraction. The fuel is then contacted with a decomposition catalyst to remove the residual organic hydroperoxide from the fuel.Type: GrantFiled: January 9, 2004Date of Patent: January 1, 2008Assignee: Lyondell Chemical Technology, L.P.Inventors: Lawrence J. Karas, Roger A. Grey, Michael W. Lynch

Patent number: 7270742Abstract: This invention is a method of purifying fuel streams containing organonitrogen and organosulfur impurities. The fuel stream is first treated to extract organonitrogen impurities so that the nitrogen content of the fuel stream is reduced by at least 50 percent. After separation and recovery of the nitrogen-depleted fuel stream, the organosulfur impurities in the fuel stream are then oxidized with an organic hydroperoxide in the presence of a titanium-containing silicon oxide catalyst. The resulting sulfones may be more readily removed from the fuel stream than the non-oxidized organosulfur impurities.Type: GrantFiled: March 13, 2003Date of Patent: September 18, 2007Assignee: Lyondell Chemical Technology, L.P.Inventors: Lawrence J. Karas, Yuan-Zhang Han, David W. Leyshon

Patent number: 7022885Abstract: The present invention relates to purification of an MTBE process stream by contact in the liquid phase with a large pore zeolite such as 13X or Zeolite Y.Type: GrantFiled: November 21, 2002Date of Patent: April 4, 2006Assignee: Arco Chemical Technology, L.P.Inventors: Lawrence J. Karas, Lawrence M. Candela, Andrew P. Kahn

Publication number: 20040178121Abstract: This invention is a method of oxidizing organosulfur impurites found in fuel streams. The method comprises reacting the organosulfur impurities with an organic hydroperoxide in the presence of a titanium-containing catalyst. The titanium-containing catalyst is obtained by impregnating a siliceous solid with a titanium halide in a hydrocarbon solvent, or a vapor stream of titanium tetrachloride, followed by calcination. The resulting sulfones are more readily removed from the fuel stream than the non-oxidized organosulfur impurities.Type: ApplicationFiled: March 13, 2003Publication date: September 16, 2004Inventors: David W. Leyshon, Lawrence J. Karas, Yuan-Zhang Han, Kevin M. Carroll
