Patent number: 8182557Abstract: The present invention provides a method for converting lignocellulosic material into biofuel. In particular embodiments, the method comprises pre-treating lignocellulosic material by dissolving the material in ionic liquids. The pretreated lignocellulosic material can be isolated, such as by precipitation with a regenerating solvent (e.g., water), and be used directly in the formation of biofuel, including undergoing hydrolysis to form sugar and fermentation to form fuel, such as bioethanol. The ionic liquid can be recycled for further use, such as by evaporation of the water introduced during precipitation, and the recycling provides a route to a hemicellulose rich fraction and an ionic liquid of consistent quality and wood dissolution characteristics. The recovered hemicelluloses are of significant utilization potential toward commodity and specialty applications.Type: GrantFiled: February 6, 2008Date of Patent: May 22, 2012Assignee: North Carolina State UniversityInventor: Dimitris Argyropoulos

Publication number: 20120077234Abstract: A method and system are provided for producing biofuel from cellulosic feedstock. In the method, the cellulosic feedstock is pretreated to separate cellulose, hemicellulose, and lignin. Thereafter, the cellulose and hemicellulose are converted into sugars through enzymatic hydrolysis. Then, the sugars are converted into lipids, e.g. triglycerides, through a microbial process. Specifically, heterotrophic microalgae is grown on the triglycerides and forms triglycerides. While triglycerides are formed from the cellulose and hemicellulose, the lignin is converted into ringed hydrocarbons, such as aromatic hydrocarbons and cycloalkanes, e.g., cycloparaffins. To form the biofuel, the triglycerides and ringed hydrocarbons are processed together. During this step, the triglycerides are converted into straight chain paraffins and esters. Preferably, the biofuel is a surrogate for jet quality JP-8 fuel.Type: ApplicationFiled: September 29, 2010Publication date: March 29, 2012Inventor: David A. Hazlebeck

Patent number: 7964761Abstract: Processes for conversion of lignin to liquid products such as bio-fuels and fuel additives are disclosed and described. A process for conversion of a lignin material to bio-fuels can include subjecting the lignin material to a base catalyzed depolymerization reaction to produce a partially depolymerized lignin. The partially depolymerized lignin can then be subjected to a stabilization/partial hydrodeoxygenation reaction to form a partially hydrodeoxygenated product. Following partial hydrodeoxygenation, the partially hydrodeoxygenated product can be reacted in a hydroprocessing step to form a bio-fuel. Each of these reaction steps can be performed in single or multiple steps, depending on the design of the process. The production of an intermediate partially hydrodeoxygenation product and subsequent reaction thereof can significantly reduce or eliminate reactor plugging and catalyst coking.Type: GrantFiled: October 31, 2007Date of Patent: June 21, 2011Assignee: University of Utah Research FoundationInventors: Wlodzimierz W. Zmierczak, Jan D. Miller

Patent number: 7960597Abstract: The present invention is directed to methods (processes) and systems for processing triglyceride-containing, biologically-derived oils to provide for base oils and transportation fuels, wherein partial oligomerization of fatty acids contained therein provide for an oligomerized mixture from which the base oils and transportation fuels can be extracted. Such methods and systems can involve an initial hydrotreating step or a direct isomerization of the oligomerized mixture.Type: GrantFiled: July 24, 2008Date of Patent: June 14, 2011Assignee: Chevron U.S.A. Inc.Inventor: Stephen Joseph Miller

Patent number: 7959765Abstract: Methods for the thermolysis of lignocellulosic materials, such as wood, cellulose, lignin, and lignocellulose are provided. Some methods comprise combining the lignocellulosic material with an ionic liquid and subjecting the mixture of the lignocellulosic material and the ionic media to thermolysis conditions to form a recoverable product, such as a commodity chemical.Type: GrantFiled: February 6, 2008Date of Patent: June 14, 2011Assignee: North Carolina State UniverstiyInventor: Dimitris Argyropoulos

Patent number: 7960599Abstract: A process for producing industrially important chemicals from renewable resources is disclosed. This “biobased” process employs readily available, renewable resources comprising fatty acids rather than exploiting fossil sources, such as coal and petroleum. In one embodiment of the process 1-octene, along with methyl-9-decenoate and butadiene, is produced from linoleic acid via an enzymemediated isomerization reaction, followed by a metathesis reaction with ethylene. Linoleic acid can be isolated from vegetable oils, such as soybean oil.Type: GrantFiled: January 13, 2004Date of Patent: June 14, 2011Assignee: Elevance Renewable Sciences, Inc.Inventors: James R. Millis, Michael J. Tupy, Timothy W. Abraham, Mervyn L. De Souza

Patent number: 7947858Abstract: In a method and apparatus for thermal processing of catalytically active biomass, the biomass is subjected in a receiving tank to a cracking temperature to undergo a cracking reaction. The biomass is transferred to a mixer pump to produce a reaction mixture which is directed into an outgassing chamber of an intermediate tank to produce an outgassed fraction and a non-outgassed liquid fraction. The outgassed fraction to produce fuel is cooled down, and a first portion of the non-outgassed liquid fraction is returned and subjected again to the cracking temperature in the receiving tank. A second portion of the non-outgassed liquid fraction is conducted in a bypass to the outgassing chamber of the intermediate tank for outgassing while fresh biomass is added. Residual matter settling in the intermediate tank is periodically removed.Type: GrantFiled: May 20, 2008Date of Patent: May 24, 2011Inventor: Jürgen Buchert
