ENGLEWOOD, US: Gevo Inc, a renewable chemicals and advanced biofuel company, received a landmark patent from the US patent and trademark office (USPTO) on its GIFT(R) separation unit, a central element in the company’s unique fermentation technology for the production of isobutanol. Gevo was awarded US patent No. 8,101,808. This patent addresses the separation technology used to produce propanols, butanols, pentanols, and hexanols. The claims also address how ethanol plants can be retrofitted to produce higher alcohols.

“This is one of several foundational Gevo patents. The technology described in this patent enables the separation of alcohols from fermentation broth using an elegantly simple design. It solves the long-standing problem for the practical production of higher alcohols, specifically how to separate these alcohol products from fermentation broth and achieve economic concentrations. This is the technology, along with our proprietary yeast, being implemented at our Luverne, Minnesota plant,” said Brett Lund, Executive Vice President, General Counsel, Gevo.
