Patent number: 8471086Abstract: We provide a process for producing hydrocarbon products. The process includes operating a process unit comprising a liquid catalyst in a first mode, adjusting a molar ratio of olefin to HCl, and operating the process unit in a second mode. The first mode and the second mode are different, one being a distillate mode and the other being a lubricant mode. Increasing the molar ratio of olefin to HCl provides a higher amount of a lubricant.Type: GrantFiled: June 28, 2010Date of Patent: June 25, 2013Assignee: Chevron U.S.A. Inc.Inventor: Sven Ivar Hommeltoft

Publication number: 20130102826Abstract: Methods for preparing selected oligomers from monomers utilize systems of equipment adapted to provide desired compositions in various streams. Representative equipment of an oligomerization system includes an oligomer synthesis reactor and, optionally, a gas/liquid phase separation system. A monomer feed stream and a catalyst feed stream are directed to the oligomer synthesis reactor. The reactor produces a vapor phase effluent and a liquid phase effluent. The selected oligomer product is withdrawn from the vapor phase effluent. When the gas/liquid phase separation system is included, it is adapted to form a first recycle stream and a separator product stream from the vapor phase effluent. The separator product stream includes the desired oligomer product. Additional equipment may be utilized to further refine the vapor phase effluent and/or the final product stream.Type: ApplicationFiled: April 17, 2012Publication date: April 25, 2013Inventors: James R. Lattner, Michael W. Weber

Publication number: 20130079575Abstract: Disclosed is a method of producing an organic compound. The method uses a metathesis catalyst in a coupling reaction of an olefin. The method comprises the steps of introducing the olefin into a container; either placing the container under vacuum or bubbling a gas through the olefin; adding an additive with the olefin; mixing the olefin and the additive, the mixing creating a mixture; adding an amount of the metathesis catalyst to the mixture, the amount being less than about 100 ppm by weight of the mixture; and optionally heating the mixture to a temperature, the temperature being greater than room temperature.Type: ApplicationFiled: September 28, 2011Publication date: March 28, 2013Inventors: Bryan M.
