1. A method of generating a reaction product comprising a mixture of an alcohol and a ketone from a biomass-derived oxygenated hydrocarbon, the method comprising:

  • catalytically reacting an aqueous feedstock solution comprising water and at least one biomass-derived, water-soluble oxygenated hydrocarbon having two or more carbon atoms with hydrogen in the presence of a catalytic material at a temperature and a pressure to produce a reaction product comprising a mixture of an alcohol and a ketone;

    wherein the catalytic material comprises;

    (a) platinum, palladium, iron, ruthenium, rhenium, copper, rhodium, cobalt, nickel, iridium, an alloy of at least two of the foregoing, or a mixture of at least two of the foregoing;

    or(b) a bi-functional catalyst selected from the group consisting of tungstated zirconia, titania zirconia, sulfated zirconia, acidic alumina, silica-alumina, a heteropolyacid, and combinations thereof.
