Patent number: 11840671Abstract: This present disclosure relates to catalytic processes for oligomerizing bio-based olefinic mixtures to higher value renewable fuels via a doped Chabazite zeolite catalyst. A stream including a C2-C8 olefin and an oxygenate is fed to an oligomerization process utilizing a doped Chabazite zeolite catalyst resulting in high yields and selectivity of oligomers used to produce bio-based jet fuel and/or diesel fuels depending upon reaction temperatures and pressures. The process also produces iso-octane that is suitable for producing bio-based gasoline. The process tolerates relatively high levels of oxygenates in the olefinic feed and the catalyst is capable of air regeneration.Type: GrantFiled: December 20, 2021Date of Patent: December 12, 2023Assignee: Gevo, Inc.Inventors: Jonathan Smith, Madeline Sjodin

Patent number: 11078433Abstract: 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: GrantFiled: April 12, 2019Date of Patent: August 3, 2021Assignee: GEVO, INC.Inventors: Jonathan O. Smith, Madeline Sjodin, Austin Vaillancourt, Paul Starkey, Steve Donen, Michelle Shebowich
