Patent number: 8530715Abstract: The present invention relates to production of fuels or fuel blendstocks from renewable sources. Various embodiments provide a method of producing a hydrocarbon product by hydrotreating a feedstock including at least one of a renewable triacylglyceride (TAG), renewable free fatty acid (FFA), and renewable fatty acid C1-C5 alkyl ester (C1-C5 FAE) in the presence of a nonsulfided hydrotreating catalyst to produce a first product including hydrocarbons. In some examples, the first product can be subjected to further chemical transformations such as aromatization, cracking, or isomerization to produce a second product including hydrocarbons. In various embodiments, the first or second hydrocarbon product with minimal or substantially no further processing can be suitable as a liquid transportation fuel or fuel blendstock, including fuels such as gasoline, naptha, kerosene, jet fuel, and diesel fuels.Type: GrantFiled: November 9, 2012Date of Patent: September 10, 2013Assignee: Energy & Environmental Research Center FoundationInventors: Joshua R. Strege, Benjamin G. Oster, Paul D. Pansegrau, Chad A. Wocken, Ted R. Aulich, Marc D. Kurz

Patent number: 8247632Abstract: A method of producing a hydrocarbon product by hydrotreating a feedstock comprising triacylglyceride (TAG) and TAG-derived materials such as free fatty acid (FFA) and fatty acid methyl ester (FAME) 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, FFA, and FAME 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. A method is described by which fatty acids may be converted to hydrocarbons suitable for use as liquid transportation fuels.Type: GrantFiled: June 27, 2009Date of Patent: August 21, 2012Assignee: Energy & Environmental Research Center FoundationInventors: Joshua R. Strege, Benjamin G. Oster, Paul D. Pansegrau, Chad A. Wocken, Ted R. Aulich, Marc Kurz
