Described are methods for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons in a single reactor. The method includes reacting a water soluble oxygenated hydrocarbon in the presence of a catalyst at a temperature, pressure, and weight hour space velocity for a time sufficient to produce a self-separating, three-phase product stream comprising a vapor phase, an organic phase, and an aqueous phase. A portion of the organic phase can be reacted to produce alkanes, alkenes, alcohols, and aromatics.

1. A method for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons, the method comprising: reacting in a single reactor an aqueous solution of a biomass-derived, water-soluble oxygenated hydrocarbon reactant, in the presence of a catalyst comprising a metal selected from the group consisting of Cr, Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, W, Re, Os, Ir, Pt, and Au, at a weight hourly space velocity of at least 0.6 h−1, at a temperature, and a pressure, and for a time sufficient to yield a self-separating, three-phase product stream comprising: a vapor phase;an organic phase comprising linear or cyclic mono-oxygenated hydrocarbons having from 4 to 6 carbon atoms and selected from the group consisting of alcohols, ketones, carboxylic acids, and 5- and 6-membered oxygen-containing heterocycles, and wherein molar carbon distribution for conversion of the water soluble oxygenated hydrocarbon reactant into the organic phase is at least 43%; andan aqueous phase; and thensubjecting the organic phase to a carbon-carbon bond-forming reaction, in the presence of a metal-containing catalyst, to yield C8-C12 compounds. 2. The method of claim 1, further comprising subjecting the C8-C12 compounds to a hydrodeoxygenation reaction to yield C8-C12 alkanes. 3. A method for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons, the method comprising: reacting in a single reactor an aqueous solution of a biomass-derived, water-soluble oxygenated hydrocarbon reactant, in the presence of a catalyst comprising a metal selected from the group consisting of Cr, Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, W, Re, Os, Ir, Pt, and Au, at a weight hourly space velocity of at least 0.6 h−1, at a temperature, and a pressure, and for a time sufficient to yield a self-separating, three-phase product stream comprising: a vapor phase;an organic phase comprising linear or cyclic mono-oxygenated hydrocarbons having from 4 to 6 carbon atoms and selected from the group consisting of alcohols, ketones, carboxylic acids, and 5- and 6-membered oxygen-containing heterocycles, and wherein molar carbon distribution for conversion of the water soluble oxygenated hydrocarbon reactant into the organic phase is at least 43%; andan aqueous phase; and thensubjecting the organic phase to an aldol condensation reaction to yield compounds having more carbon atoms than the reactant. 4. A method for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons, the method comprising: reacting in a single reactor an aqueous solution of a biomass-derived, water-soluble oxygenated hydrocarbon reactant, in the presence of a catalyst comprising a metal selected from the group consisting of Cr, Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, W, Re, Os, Ir, Pt, and Au, at a weight hourly space velocity of at least 0.6 h−1, at a temperature, and a pressure, and for a time sufficient to yield a self-separating, three-phase product stream comprising: a vapor phase;an organic phase comprising linear or cyclic mono-oxygenated hydrocarbons having from 4 to 6 carbon atoms and selected from the group consisting of alcohols, ketones, carboxylic acids, and 5- and 6-membered oxygen-containing heterocycles, and wherein molar carbon distribution for conversion of the water soluble oxygenated hydrocarbon reactant into the organic phase is at least 43%; andan aqueous phase; and thenhydrogenating the organic phase, wherein ketones present in the organic phase are reduced to alcohols; and then dehydrating the alcohols to yield alkenes. 5. The method of claim 4, further comprising: subjecting the alkenes to alkylation reaction over an acid catalyst to form carbon-carbon bonds, thereby yielding longer chain alkenes. 6. A method for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons, the method comprising: reacting in a single reactor an aqueous solution of a biomass-derived, water-soluble oxygenated hydrocarbon reactant, in the presence of a catalyst comprising a metal selected from the group consisting of Cr, Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, W, Re, Os, Ir, Pt, and Au, at a weight hourly space velocity of at least 0.6 h−1, at a temperature, and a pressure, and for a time sufficient to yield a self-separating, three-phase product stream comprising: a vapor phase;an organic phase comprising linear or cyclic mono-oxygenated hydrocarbons having from 4 to 6 carbon atoms and selected from the group consisting of alcohols, ketones, carboxylic acids, and 5- and 6-membered oxygen-containing heterocycles, and wherein molar carbon distribution for conversion of the water soluble oxygenated hydrocarbon reactant into the organic phase is at least 43%; andan aqueous phase; and thenhydrogenating the organic phase, wherein ketones present in the organic phase are reduced to alcohols. 7. The method of claim 6, further comprising converting the alcohols so formed to aromatic compounds. 8.
