Patent number: 9732283Abstract: System relating to the conversion of ethanol in a stripper unit of a fluidized catalytic cracking system. An ethanol stream comprising at least 4 volume percent water mixes with a catalyst in the stripper unit under conditions of temperature that favor conversion of the ethanol to hydrocarbons, thereby increasing incorporation of ethanol into liquid transportation fuels without exceeding regulatory limits on fuel vapor pressure. Certain embodiments additionally combine the ethanol stream with a hydrocarbon stream in the stripper and react in the presence of a catalyst to produce hydrocarbons that may have an increased boiling point, increased octane rating, decreased vapor pressure, decreased benzene content, or combinations of these properties.Type: GrantFiled: December 10, 2015Date of Patent: August 15, 2017Assignee: PHILLIPS 66 COMPANYInventors: Jianhua Yao, William D. Henning, Walter E. Alvarez

Patent number: 8992766Abstract: A method of upgrading naphtha and diesel yields from fluid catalytic cracking and hydrocracking units by improving a feed quality of a petroleum feedstock, product or fraction mixture. The method of improving the feed quality of the petroleum feedstock, product or fraction mixture occurs by first determining the API Gravity of a petroleum feedstock, product or fraction mixture. A temperature at which about fifty percent of the petroleum feedstock, product or fraction boils (T50) is then determined. The feed quality for the petroleum feedstock, product or fraction mixture as determined from the API Gravity and the T50 for the feedstock, product or fraction mixture is then estimated followed by adjusting the petroleum feedstock, product or fraction mixture to achieve a higher feed quality.Type: GrantFiled: June 17, 2011Date of Patent: March 31, 2015Assignee: Phillips 66 CompanyInventors: Tushar V. Choudhary, Walter E. Alvarez, Joseph E. Bares

Patent number: 7459138Abstract: A process and apparatus for catalytic production of single walled carbon nanotubes. Catalytic particles are exposed to different process conditions at successive stages wherein the catalytic particles do not come in contact with reactive (catalytic) gases until preferred process conditions have been attained, thereby controlling the quantity and form of carbon nanotubes produced. The reaction gas is preferably provided at a high space velocity to minimize CO2 build-up. The process also contemplates processes and apparatus which recycle and reuse the gases and catalytic particulate materials, thereby maximizing cost efficiency, reducing wastes, reducing the need for additional raw materials, and producing the carbon nanotubes, especially SWNTs, in greater quantities and for lower costs.Type: GrantFiled: October 28, 2004Date of Patent: December 2, 2008Assignee: The Board of Regents of the University of OklahomaInventors: Daniel E. Resasco, Boonyarach Kitiyanan, Walter E. Alvarez, Leandro Balzano

Patent number: 7357907Abstract: A catalyst composition and method of use of the catalyst composition for producing single-walled carbon nanotubes (SWNTs). The catalyst is cobalt (Co) and molybdenum (Mo) on a silica support. The Mo occurs primarily as dispersed Mo oxide clusters on the support while the Co is primarily in an octahedral configuration in a CoMoO4-like phase disposed on the Mo oxide clusters. In the method, the catalyst is used and the process conditions manipulated in such a manner as to enable the diameters of the SWNTs to be substantially controlled.Type: GrantFiled: October 20, 2003Date of Patent: April 15, 2008Assignee: The Board of Regents of the University of OklahomaInventors: Daniel E.
