摘要： This present disclosure relates to catalytic processes for upgrading crude and/or refined fusel oil mixtures to higher value renewable chemicals, via mixed metal oxide or zeolite catalysts. Disclosed herein are processes passing a vaporized stream of crude and/or refined fusel oils over various mixed metal oxide catalysts, metal doped zeolites, or non-metal doped zeolites and/or metal oxides providing options to valorize fusel oil mixtures to higher value products. Renewable chemicals formed, via these upgrading catalyst platforms, are comprised of, but not limited to, methyl isobutyl ketone (MIBK), di-isobutyl ketone (DIBK), isoamylene, and isoprene.

摘要： 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.

摘要： This application relates to the production of functionalized lower hydrocarbons and more particularly to the process of converting ethanol to functionalized lower hydrocarbons. In particular embodiments, the ethanol to functionalized lower hydrocarbon conversion is catalyzed by a ZnxZryAvQsMnwOz mixed oxide catalyst or a bifunctional heterogeneous catalyst. In particular embodiments, the ethanol to be converted is present at molar concentrations in the reactor feed equal to or exceeding 14%.
