The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. Water is added to the deoxygenation reaction to drive carbon monoxide and water to react to form hydrogen and carbon dioxide. The hydrogen is then consumed by the reactions. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties.Type: GrantFiled: August 18, 2008Date of Patent: August 16, 2011Assignees: UOP LLC, ENI S.p.A.Inventors: Terry L. Marker, Peter Kokayeff, Giovanni Faraci, Franco Baldiraghi

Patent number: 7989671Abstract: A method of producing a hydrocarbon product by hydrotreating a feedstock comprising triacylglyceride (TAG) in the presence of a nonsulfided hydrotreating catalyst to produce a first product comprising hydrocarbons. A method of producing a transportation fuel by selecting an undoped feedstock comprising virgin TAG, used TAG, or a combination thereof; hydrotreating the undoped feedstock in the presence of an unsulfided hydrotreating catalyst to produce a first product; and subjecting the first product to at least one process selected from aromatization, cyclization, and isomerization; to produce a second hydrocarbon product selected from gasoline, kerosene, jet fuel, and diesel fuels.Type: GrantFiled: November 4, 2008Date of Patent: August 2, 2011Assignee: Energy & Environmental Research Center FoundationInventors: Joshua R. Strege, Benjamin G. Oster, Paul D. Pansegrau, Chad A. Wocken, Ted R. Aulich

Patent number: 7977391Abstract: Process for the production of a condensed-phase product from one or more gas-phase reactants, by feeding one or more reactants into a reactor, in which reactor the one or more reactants react in the gas-phase in the presence of a solid catalyst having one or more catalyst components to produce at least one product which is in a condensed-phase under reaction conditions. The solid catalyst is present as a bed having two or more regions in which the contact time of the one or more gas-phase reactants with the one or more catalyst components is different.Type: GrantFiled: November 22, 2006Date of Patent: July 12, 2011Assignee: BP Exploration Operating Company LimitedInventor: Sander Gaemers

Patent number: 7964764Abstract: A method of synthesizing hydrocarbons from smaller hydrocarbons includes the steps of hydrocarbon halogenation, simultaneous oligomerization and hydrogen halide neutralization, and product recovery, with a metal-oxygen cataloreactant used to facilitate carbon-carbon coupling. Treatment with air or oxygen liberates halogen and regenerates the cataloreactant.Type: GrantFiled: January 7, 2010Date of Patent: June 21, 2011Assignee: GRT, Inc.Inventor: Ivan M. Lorkovic
