Publication number: 20040020824Abstract: Provide is a novel gasoline composition which is substantially free of oxygenates and is in compliance with the California Predictive Model. The gasoline composition is suitable for use in the winter months, i.e., having a Reid vapor pressure in the range of greater than 7.0 to about 15.0 psi. The method for blending the gasoline comprises blending streams from a refinery in a controlled manner to maintain compliance with the California Predictive Model.Type: ApplicationFiled: April 3, 2003Publication date: February 5, 2004Inventors: Scott R. Brundage, David A. Kohler, Richard T. Engle

Patent number: 6566569Abstract: A process for preparing a C4- product stream and a C6+ product stream is disclosed. The process involves contacting a C5 containing paraffinic feedstock with a catalyst that includes a hydrogenation/dehydrogenation catalyst and an olefin metathesis catalyst under conditions which dehydrogenate the paraffins to olefins. The olefins are then metathesized and rehydrogenated to provide a product stream. A C4- fraction and a C6+ fraction can each be isolated from the product stream. The C4- fraction can be used, for example, in an alkylation reaction to provide compounds useful in gasoline compositions. Unconverted C5 paraffins can be recycled. The C6+ fraction can be used, for example, as solvents. Alternatively, they can be isomerized to form gasoline additives, or can be converted to aromatic compounds via reforming, for example, using conventional reforming techniques, preferably using the AROMAX™ process or traditional rheniforming conditions.Type: GrantFiled: June 23, 2000Date of Patent: May 20, 2003Assignee: Chevron U.S.A.

Patent number: 6383236Abstract: Provided is an unleaded gasoline fuel which is substantially free of oxygenates, i.e., the fuel contains less than 1.0 weight percent oxygen based on the total weight of the fuel composition, and most preferably contains no oxygen containing compounds. The gasoline fuel of the present invention also has a Reid vapor pressure of less than 7.5 psi, a sulfur content of less than 30 ppmw, and more preferably less than 20 ppmw sulfur, and an aromatic hydrocarbon content greater than 30 volume percent and/or a 50% D-86 Distillation Point greater than 220° F. and/or a 90% D-86 Distillation Point greater than 330° F. The gasoline fuel preferably also has an olefin content of no greater than 8 volume percent, and more preferably 5 volume percent or less. It has been found that such a gasoline fuel offers a substantially oxygenate free gasoline which avoids the environmental impact of oxygenates, yet when combusted in an internal combustion automobile provides good performance and good emissions.Type: GrantFiled: May 23, 2000Date of Patent: May 7, 2002Assignee: Chevron U.S.A.

Patent number: H2182Abstract: Provided is an unleaded gasoline fuel which is substantially free of oxygenates, and most preferably contains substantially zero oxygenates. The gasoline fuel also has a Reid vapor pressure less then 7.5 psi, a sulfur content less than 30 ppmw, an aromatic hydrocarbon content between 25 and 30 volume percent, and/or a 50% D-86 Distillation Temperature between 210 and 220° F., and/or a 90% D-86 Distillation Temperature between 300 and 330° F., and the fuel composition fails the California Predictive Model requirements for emissions. Preferably, the olefin content of the fuel is also 8 volume percent or less. Such a gasoline fuel offers a substantially oxygenate free gasoline which avoids the environmental impact of oxygenates, yet when combusted in an internal combustion automobile provides good performance and good emissions, despite failing the California Predictive Model. The gasoline fuel in particular can provide surprisingly lower NOx emissions than that predicted by the California Predictive Model.Type: GrantFiled: January 24, 2000Date of Patent: February 6, 2007Assignee: Chevron U.S.A.
