  • Patent number: 11078433
    Abstract: The present disclosure provides methods and materials for oligomerization of lower olefins (e.g., C2-C8) to transportations fuels including diesel and/or jet fuel. The oligomerization employs, in certain embodiments, tungstated zirconium catalysts. Surprisingly, the oligomerizations proceed smoothly in high yields and exhibit little to no sensitivity to the presence of significant amounts of oxygenates (e.g., water, lower alcohols such as C2-C8 alcohols) in the feed stream. Accordingly, the present disclosure is uniquely suited to the production of fuels derived from bio-based alcohols, wherein olefins produced from such bio-based alcohols typically contain high levels of oxygenates.
    Type: Grant

    Date of Patent: August 3, 2021
    Assignee: GEVO, INC.
    Inventors: Jonathan O. Smith, Madeline Sjodin, Austin Vaillancourt, Paul Starkey, Steve Donen, Michelle Shebowich
