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
