Patent number: 10577291Abstract: A method for producing jet-range hydrocarbons includes passing a stream comprising renewable C4 olefins to an oligomerization reactor containing a zeolite catalyst to produce an oligomerized effluent, separating the oligomerized effluent to produce a jet range hydrocarbon stream and a recycle stream comprising C8 olefins, and passing at least a portion of the recycle stream to the oligomerization reactor. A first at least about 10% of the jet-range hydrocarbon stream hydrocarbons boil between n-octane and n-undecane and wherein a second at least about 10% of the jet-range hydrocarbon stream hydrocarbons boil between n-dodecane and n-pentadecane.Type: GrantFiled: November 6, 2013Date of Patent: March 3, 2020Assignee: UOP LLCInventors: Stanley Joseph Frey, Geoffrey William Fichtl, Paul Barger, Scott M.

Patent number: 9567541Abstract: A jet-range hydrocarbon product includes a mixture of paraffins. The mixture exhibits a freeze point of less than or equal to about ?70° C., a 95% distillation point of greater than or equal to about 275° C., and a smooth boiling point curve that is characterized as having no intervals of the boiling point curve having a slope that is steeper than 4° C./mass % as defined by ASTM standard D2887 between mass recovered ranges of about 20% to about 80%. The steepness of the boiling point curve slope is calculated over any 10 mass % increments within the specified mass % ranges.Type: GrantFiled: November 6, 2013Date of Patent: February 14, 2017Assignee: UOP LLCInventors: Stanley Joseph Frey, Geoffrey William Fichtl, Paul Barger, Scott M.

Publication number: 20160090333Abstract: Methods and apparatus are provided for producing jet-range hydrocarbons from biorenewable sources, such as oligomerizing C3-C8 biorenewable olefins, for example, derived from C3-C8 alkanol products of fermentation of biomass. Production of jet-range hydrocarbons is increased by employing an additional oligomerization zone for oligomerizing naphtha separated from the effluent of a primary oligomerization zone wherein the C3-C8 biorenewable olefins were first subjected to oligomerization.Type: ApplicationFiled: September 26, 2014Publication date: March 31, 2016Inventors: Dana K. Sullivan, Charles P. Luebke, Christopher P. Nicholas, Geoffrey William Fichtl

Publication number: 20160068453Abstract: Methods are provided for producing normal paraffins. A method includes contacting a feedstock with a deoxygenation catalyst to produce a paraffin stream, where the feedstock includes a natural oil, and where the deoxygenation catalyst is sulfided. The reactions conditions are controlled when the feedstock contacts the deoxygenation catalyst to control a C11 to C12 normal paraffin ratio, by weight to within about 0.4 to about 1.7.Type: ApplicationFiled: September 10, 2014Publication date: March 10, 2016Inventors: Geoffrey William Fichtl, Daniel Ellig

Publication number: 20150376081Abstract: Apparatuses and methods for producing linear alkylbenzene products from renewable oils are provided. An exemplary method includes deoxygenating the renewable oil in a deoxygenation zone to form paraffins. The method fractionates the paraffins to form first and second fractions. The method processes the first fraction of paraffins in a reforming zone to form a reformate stream and recovers a first hydrogen stream from the reforming zone. The method includes forming a LAB stream in a LAB production zone from the second fraction of paraffins and a portion of the reformate stream. Further, the method includes recovering a second hydrogen stream in the LAB production zone and recycling the first hydrogen stream from the reforming zone and the second hydrogen stream from the LAB production zone, wherein substantially all hydrogen recovered from the reforming zone and the LAB production zone is recycled.Type: ApplicationFiled: June 30, 2014Publication date: December 31, 2015Inventors: Debarshi Majumder, Geoffrey William Fichtl

Publication number: 20150094506Abstract: Methods and systems are provided for producing a fuel from a renewable feedstock. The method includes deoxygenating the renewable feedstock in a deoxygenation zone to produce hydrocarbons with normal paraffins. The hydrocarbons with normal paraffins are isomerized to produce hydrocarbons with branched paraffins. The hydrocarbons with branched paraffins are fractionated to produce a naphtha at a naphtha outlet, where the naphtha is further isomerized.Type: ApplicationFiled: September 27, 2013Publication date: April 2, 2015Applicant: UOP LLCInventors: Geoffrey William Fichtl, Jonathan Arana, Daniel L.

Patent number: 8916739Abstract: Methods and apparatuses for preparing normal paraffins and hydrocarbon product streams are provided herein. A method of preparing normal paraffins includes providing an unsaturated feed that includes an unsaturated compound that has at least one alkenyl group. The unsaturated feed is epoxidized to convert the at least one alkenyl group in the unsaturated compound to an epoxide functional group, thereby converting the unsaturated compound to an epoxide compound that has at least one epoxide functional group. The at least one epoxide functional group in the epoxide compound is converted to at least one secondary hydroxyl functional group, thereby converting the epoxide compound to a hydroxyl-functional compound that has at least one hydroxyl functional group. The hydroxyl-functional compound is deoxygenated to form normal paraffins.Type: GrantFiled: December 12, 2012Date of Patent: December 23, 2014Assignee: UOP LLCInventors: Geoffrey William Fichtl, Daniel Ellig, Stanley Joseph Frey, Michael J.

Publication number: 20140296590Abstract: Embodiments of methods and apparatuses for processing a renewable feedstock are provided herein. In one example, a method comprises dividing a H2-rich make-up stream into a first H2-rich portion and a second H2-rich portion. The second H2-rich portion has a lower mass flow rate than the first H2-rich portion. The renewable feedstock is deoxygenated in the presence of the first H2-rich portion at hydroprocessing conditions effective to form a deoxygenating reaction zone effluent that contains normal paraffins. At least a portion of the deoxygenating reaction zone effluent is isomerized in the presence of the second H2-rich portion at isomerization conditions effective to form an isomerization reaction zone effluent that contains branched paraffin. The isomerization conditions include a first hydrogen partial pressure of about 4,140 kPa gauge or less.Type: ApplicationFiled: March 29, 2013Publication date: October 2, 2014Applicant: UOP LLCInventors: Charles P.
