Filed:

Dec 23, 2008

Appl. No.:

12/342992

Inventors:

William A. Evanko - Golden CO, US
Aharon M. Eyal - Jerusalem, IL
David A. Glassner - Littleton CO, US
Fudu Miao - Chester Springs PA, US
Aristos A. Aristidou - Highlands Ranch CO, US

Patrick R. Gruber - Longmont CO, US
Andrew C. Hawkins - Parker CO, US

Assignee:

GEVO, Inc. - Englewood CO

International Classification:

C07C 29/76

US Classification:

568916

Abstract:

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.
