TiO2-supported ruthenium catalysts produced deoxygenated compounds that included aromatic and cyclohexyl molecules. A hydrogen-pressure-dependent deoxygenation pathway was inferred from the detected intermediates. With iron added to Ru/TiO2 (Ru/Fe/TiO2), the carbon yield to C6–C8 deoxygenated compounds reached 61.1%. Proximity of Ru to Fe oxides depleted the electron density of Ru, adjusted its catalytic activity, and suppressed excessive hydrocracking, which preserved high yields of C6–C7 hydrocarbons.
