Summary:We report on a new pyrolytic pathway for biomass conversion to hydrocarbon fuel precursors. The process entails the conversion of multifunctional oxygenates generated from biomass pyrolysis over a metal oxide catalyst into ketonic-rich monofunctional molecules suitable for making hydrocarbon fuel components for gasoline, diesel, and jet fuel. A number of catalysts were explored, for example, anatase TiO sub(2) nanorods, CeO sub(x)-TiO sub(2) mixed oxides, pure CeO sub(2), ZrO sub(2), and MgO. Under pyrolysis conditions, ceria-based catalysts were effective in the conversion of hydroxy-carbonyls, anhydrosugars, and carboxylic acids into acetone, 2-butanone, pentanones, C6/C7 ketones, cyclopentanone, and 2-cyclopentenones. The highest carbon yield (23.5%) of ketonic precursors was achieved on the pure CeO sub(2).
