Such amine catalysts may be supported, for example, on a silica-alumina support. Such amine catalysts may be used in the presence of an additional acid. The ?,?-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such ?,?-unsaturated ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketones may be obtained from renewable sources, such as by the fermentation of biomass.

  • Publication number: 20150191686
    Abstract: Methods of producing renewable materials may include consuming a fermentation feedstock with a fermentation organism to produce a renewable material in fermentation broth; water may then be separated from the feedstock or broth using one or more phase separations, or the renewable material may be concentrated from the feedstock or broth using one or more phase separations. Methods of producing biofuel components may include consuming a lignocellulosic or sugar fermentation feedstock with a fermentation organism to produce either ethanol or butanol in fermentation broth; cooling the feedstock or broth to solidify at least some water therein; and separating the solidified water from the feedstock or broth using a solid-liquid phase separation.

  • Patent number: 8835660
    Abstract: The invention provides a method to extract organic compounds from aqueous mixtures, using a specially selected organic compound as an extraction liquid. The method can be applied to remove compounds such as acetic acid or ethanol from complex aqueous mixtures, including fermentation reactions or broths, and can be used for in situ extraction of products or by-products from a fermentation reaction. Some suitable extraction liquids for use in these methods include diethylene glycol dibutyl ether, tripropionin, and di(ethylene glycol) diisobutyl ether.
