Total Cray Valley and Gevo successfully complete phase 1 of fusel oil upgrade

May 4, 2021 |

In Colorado, Total Cray Valley and Gevo, Inc. announced the successful completion of phase 1 of their Joint Development Agreement (JDA) to upgrade fusel oils into renewable isoamylene. The companies are now seeking to advance to Phase 2 of the JDA, which will allow for scale up of Gevo’s technology at a demonstration scale.

Fusel oils, made during the production of ethanol, equate to approximately 1 million tons of bio-based feedstock. The JDA, signed in 2020, is based on Gevo’s chemical-based catalytic processes that selectively convert low-value fusel oils, a mixture of alcohols that are byproducts from fermentation processes such as ethanol or isobutanol production, into higher-value renewable chemicals such as isoprene, ketones, aldehydes, or olefins, in this case isoamylene.

Isoamylene is used in a diverse set of applications, including resins, pesticides, flavors and fragrances, pharmaceuticals, healthcare products, adhesives, antioxidants, and UV stabilizers. For Cray Valley, isoamylene is used as a raw material in resin
