TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The support is modified by treating the support with molybdenum, tungsten or a tungsten oxide. The deoxygenation temperature is 120-300 degrees C, preferably 200-280 degrees C. The condensation temperature is 250-425 degrees C or 125-450 degrees C, and where the condensation pressure is 0-700 psig, where the condensation reaction takes place in the vapor phase. Preferred Components: The acid catalyst further comprises a member consisting of copper, silver, gold, platinum, nickel, cobalt, rubidium, zinc, gallium, rhodium, palladium, iridium, rhenium, manganese, chromium, molybdenum, tungsten, tin, and/or their alloys. The acid catalyst comprises a zeolite consisting of ZSM-5 (preferred), ZSM-11, ZSM-22, ASM-23, ASM-35 or ZSM-48. The deoxygenation catalyst further comprises a member of chromium, vanadium, niobium, titanium, zirconium, yttrium, lanthanum, zinc, cadmium, gold, tin, germanium, phosphorus, aluminum, gallium and/or indium. The support comprises a member consisting of a carbon, alumina, zirconia, titania, vanadia, heteropolyacid, hydroxyapatite and/or chromia.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The oxygenated hydrocarbon comprises a member consisting of starches, polysaccharides, disaccharides, monosaccharides, cellulose derivatives, lignin derivatives, hemicellulose, sugars and/or sugar alcohols. The oxygenate comprises two or more members consisting of an alcohol, ketone, aldehyde, carboxylic acid, diol, cyclic ether, furan or furfural. EXAMPLE - A bimetallic catalyst system containing platinum and rhenium (5 wt.% platinum with a molar ratio of 1:2.5) supported on activated carbon was prepared. Activated carbon was added slowly to a hydrogen peroxide solution (30%). After addition of the carbon was completed, the mixture was left overnight. The aqueous phase was decanted and the carbon was washed three times with deionized water, and then dried under vacuum at 100 degrees C. An aqueous solution, with a volume equal to incipient wetness volume for the carbon to be impregnated (10.4 ml), and containing dihydrogen hexachloroplatinate (IV) hexahydrate (39.85% platinum) and perrhenic acid solution (76.41% perrhenic acid) was added dropwise, while stirring, to hydrogen peroxide functionalized carbon. The wetted carbon was dried at 100 degrees C under vacuum to obtain C5+ compounds.
