Abstract

Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C4+ hydrocarbons, alcohols and/or ketones, by condensation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

Independent Claims | See all claims (147)

  1. 1. A method of making a C4+ compound comprising: providing water and a water soluble oxygenated hydrocarbon comprising a C1+O1+ hydrocarbon in an aqueous liquid phase and/or a vapor phase, providing H2, catalytically reacting in the liquid and/or vapor phase the oxygenated hydrocarbon with the H2 in the presence of a deoxygenation catalyst at a deoxygenation temperature and deoxygenation pressure to produce an oxygenate comprising a C1+O1-3 hydrocarbon in a reaction stream, and catalytically reacting in the liquid and/or vapor phase the oxygenate in the presence of an acid catalyst at a condensation temperature and condensation pressure to produce the C4+ compound, wherein the C4+ compound comprises a member selected from the group consisting of C4+ alcohol, C4+ ketone, C4+ alkane, C4+ alkene, C5+ cycloalkane, C5+ cycloalkane, aryl, fused aryl, and a mixture thereof.
  2. 104. A method of making a C4+ compound comprising: providing water and a water soluble oxygenated hydrocarbon comprising a C1+O1+ hydrocarbon in an aqueous liquid phase and/or a vapor phase, catalytically reacting a portion of the water and oxygenated hydrocarbon in the liquid phase and/or vapor phase in the presence of an aqueous phase reforming catalyst at a reforming temperature and a reforming pressure to produce in situ generated H2, catalytically reacting in the liquid and/or vapor phase the oxygenated hydrocarbon with the in situ generated H2 in the presence of a deoxygenation catalyst at a deoxygenation temperature and deoxygenation pressure to produce an oxygenate comprising a C1+O1-3 hydrocarbon in a reaction stream, and catalytically reacting in the liquid and/or vapor phase the oxygenate in the presence of an acid catalyst at a condensation temperature and condensation pressure to produce the C4+ compound, wherein the C4+ compound comprises a member selected from the group consisting of C4+ alcohol, C4+ ketone, C4+ alkane, C4+ alkene, C5+ cycloalkane, C5+ cycloalkene, aryl, fused aryl, and a mixture thereof.
  3. 140.
