Patent number: 8742187Abstract: The method of the present invention provides a high yield pathway to 2,5-dimethylhexadiene from renewable isobutanol, which enables economic production of renewable p-xylene (and subsequently, terephthalic acid, a key monomer in the production of PET) from isobutanol. In addition, the present invention provides methods for producing 2,5-dimethylhexadiene from a variety of feed stocks that can act as “equivalents” of isobutylene and/or isobutyraldehyde including isobutanol, isobutylene oxide, and isobutyl ethers and acetals. Catalysts employed in the present methods that produce 2,5-dimethylhexadiene can also catalyze alcohol dehydration, alcohol oxidation, epoxide rearrangement, and ether and acetal cleavage.Type: GrantFiled: April 19, 2012Date of Patent: June 3, 2014Assignee: GEVO, Inc.Inventors: Thomas Jackson Taylor, Joshua D.

Patent number: 8614077Abstract: This invention is directed to methods for recovery of C3-C6 alcohols from dilute aqueous solutions, such as fermentation broths. Such methods provide improved volumetric productivity for the fermentation and allows recovery of the alcohol. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried. Thus, the invention allows for production and recovery of C3-C6 alcohols at low capital and reduced operating costs.Type: GrantFiled: November 22, 2011Date of Patent: December 24, 2013Assignee: Gevo, Inc.Inventors: William A. Evanko, Aharon M. Eyal, David A. Glassner, Fudu Miao, Aristos A. Aristidou, Kent Evans, Patrick R. Gruber, Andrew C. Hawkins, Peter Meinhold, Reid M. Renny Feldman, Uvini Gunawardena, Jun Urano

Publication number: 20130261323Abstract: Isobutene, isoprene, and butadiene are obtained from mixtures of C4 and/or C5 olefins by dehydrogenation. The C4 and/or C5 olefins can be obtained by dehydration of C4 and C5 alcohols, for example, renewable C4 and C5 alcohols prepared from biomass by thermochemical or fermentation processes. Isoprene or butadiene can be polymerized to form polymers such as polyisoprene, polybutadiene, synthetic rubbers such as butyl rubber, etc. in addition, butadiene can be converted to monomers such as methyl methacrylate, adipic acid, adiponitrile, 1,4-butadiene, etc. which can then be polymerized to form nylons, polyesters, polymethylmethacrylate etc.Type: ApplicationFiled: May 24, 2013Publication date: October 3, 2013Applicant: GEVO, INC.Inventors: Matthew W.
