    摘要： Described is a method to make liquid chemicals, such as functional intermediates, solvents, and liquid fuels from biomass-derived cellulose. The method is cascading; the product stream from an upstream reaction can be used as the feedstock in the next downstream reaction. The method includes the steps of deconstructing cellulose to yield a product mixture comprising levulinic acid and formic acid, converting the levulinic acid to γ-valerolactone, and converting the γ-valerolactone to pentanoic acid. Alternatively, the γ-valerolactone can be converted to a mixture of n-butenes. The pentanoic acid so formed can be further reacted to yield a host of valuable products. For example, the pentanoic acid can be decarboxylated yield 1-butene or ketonized to yield 5-nonanone. The 5-nonanone can be hydrodeoxygenated to yield nonane, or 5-nonanone can be reduced to yield 5-nonanol. The 5-nonanol can be dehydrated to yield nonene, which can be dimerized to yield a mixture of C9 and C18 olefins, which can be hydrogenated to yield a mixture of alkanes. Alternatively, the nonene may be isomerized to yield a mixture of branched olefins, which can be hydrogenated to yield a mixture of branched alkanes. The mixture of n-butenes formed from γ-valerolactone can also be subjected to isomerization and oligomerization to yield olefins in the gasoline, jet and Diesel fuel ranges.

    摘要： Disclosed is a method for preparing liquid fuel and chemical intermediates from biomass-derived oxygenated hydrocarbons. The method includes the steps of 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 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 containing linear and/or cyclic mono-oxygenated hydrocarbons, and an aqueous phase.

    摘要： A method for catalytically reducing the carboxylic acid group of hydroxycarboxylic acids to a hydroxyl group is disclosed. An organic compound having an &agr;-hydroxyl group and at least one carboxylic acid group is contacted with a catalyst in the presence of hydrogen to yield a reduced product having at least two hydroxyl groups, the carboxylic acid group having been converted into one of the hydroxyl groups. The catalytic process may be conducted at hydrogen pressures of less than about 50 atm and is particularly suited for converting &agr;-hydroxycarboxylic acids, such as lactic acid or glycolic acid, to 1,2-dihydroxy alkanes, such as 1,2-propanediol or ethylene glycol, using zero valent copper. The catalyst may be supported on silica, and the hydroxyl groups on the silica may be capped with hydrophobic groups including alkyl groups and silanes, such as trialkylsilanes.
