Gevo enters on-road automobile gasoline market in Houston with 12.5% isobutanol blend

November 12, 2016

Gevo, Inc. announced that a 12.5% blend of its bio-isobutanol with gasoline marketed for use in automobiles has begun to be sold in the Houston area. This marks the first time that Gevo’s isobutanol has been specifically targeted towards on-road vehicles. Previously, Gevo and its partners have focused on specialty markets such as marinas and off-road engines. (Earlier post.)

Musket Corporation is Gevo’s distribution partner serving the Houston market and is blending the specially formulated gasoline containing Gevo’s isobutanol to distribute into the on-road automobile market. Buc-ee’s, a 37-store regional chain of rest stops in Texas, is the first company to sell the blend, marketed as a high-performance ethanol-free gasoline.

Bio-isobutanol company Gevo signs licensing and joint development agreements with Porta in Argentina; corn feedstock

February 03, 2016

Gevo, Inc. has entered into a license agreement and a joint development agreement with Porta Hnos S.A. to construct multiple isobutanol plants in Argentina using corn as a feedstock.

The first plant is to be wholly owned by Porta and is anticipated to begin producing isobutanol in 2017. The plant is expected to have a production capacity of up to five million gallons of isobutanol per year. Based on projected isobutanol pricing, Gevo estimates that it could generate approximately $1 million in annual revenues once the plant is operational, through royalties, sales and marketing fees, and other revenue streams such as yeast sales.

Researchers improve efficiency of ethanol-to-butanol conversion with new bifunctional catalyst

December 04, 2015

Researchers at the University of Rochester and the University of Ottawa (Canada) have developed a highly selective (>99%) tandem catalytic system—a bifunctional iridium catalyst coupled with bulky nickel or copper hydroxides—for the conversion of ethanol (up to 37%) to n-butanol, through the Guerbet process.

The team was able to increase the amount of ethanol converted to butanol by almost 25% over currently used methods without producing unwanted byproducts. A paper describing the new system is published in the Journal of the American Chemical Society.
