Patent number: 8586805Abstract: A method comprising the steps of providing a fatty acyl mixture comprising: (i) a C10-C16 acyl carbon atom chain content of at least 30 wt. % wherein at least 80% of the C10-C16 acyl carbon atom chains are saturated; and (ii) a C18-C22 acyl carbon atom chain content of at least 20 wt. % wherein at least 50% of the acyl C16-C22 carbon atom chains contain at least one double bond; hydrolyzing at least some of the mixture to yield a quantity of C10-C16 saturated fatty acids and C18-C22 unsaturated fatty acids; oligomerizing at least some of the C18-C22 unsaturated fatty acids to yield a quantity of C36+ fatty acid oligomers; separating at least some of the C10-C16 saturated fatty acids from the C36+ fatty acid oligomers.Type: GrantFiled: October 28, 2010Date of Patent: November 19, 2013Assignee: Chevron U.S.A. Inc.Inventor: Stephen J. Miller

Patent number: 8586807Abstract: Disclosed herein is the use of terrestrial plant materials (e.g., leaves and bark) that contain biopolymer materials to produce hydrocarbon-rich crude oils that can be refined further into hydrocarbon-based biofuels, via the hydrous pyrolysis method, which involves heating to subcritical temperatures and pressures in an aqueous medium. One can also isolate the aliphatic biopolymers and utilize them as feedstocks for production of the hydrocarbon-rich crude via hydrous pyrolysis.Type: GrantFiled: May 14, 2012Date of Patent: November 19, 2013Assignee: Old Dominion University Research FoundationInventor: Patrick G. Hatcher

Patent number: 8581013Abstract: The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The method also includes separating the naphtha fraction and optionally recycling the hydrocracking unit heavy fraction through the hydrocracking unit. The present invention also relates to a biorenewable naphtha product suitable for use as feed stock for steam crackers and catalytic reforming units, and for use as fuel, or fuel blend stock.Type: GrantFiled: August 2, 2011Date of Patent: November 12, 2013Assignee: Syntroleum CorporationInventors: Ramin Abhari, H.

Patent number: 8581014Abstract: Provided is a process for producing, in a single step, hydrocarbon fractions useful as diesel fuel or as a component of diesel fuel, from a mixture of a biological origin containing esters of fatty acids and, optionally, aliquots of free fatty acids. The process comprises the contemporaneous hydrodeoxygenation and hydroisomerization of the mixture of a biological origin, with the formation of linear and branched paraffins. The process is carried out in the presence of a catalytic composition comprising an amorphous carrier of an acidic nature and a metallic component containing one or more metals of group VIII.Type: GrantFiled: December 14, 2009Date of Patent: November 12, 2013Assignees: ENI S.p.A., UOP LLCInventors: Carlo Perego, Franco Baldiraghi, Suheil Fares Abdo, Terry Louise Marker, Luigina Maria Flora Sabatino
