Hydrogenation of bio-oil into higher alcohols over Ru/Fe3O4-SiO2 catalysts
Liquid-phase hydrogenation of a solution of furfural, phenol and acetic acid has been studied in the 50-235 degrees C range over magnetic Ru/Fe3O4-SiO2 catalyst targeting the renewable production of second generation biofuels with minimum hydrogen consumption. Phenol was fully hydrogenated to cyclohexanol in the entire temperature range. Below 150 degrees C, furfural was mainly hydrogenated to tetrahydrofurfuryl alcohol while hydrogenolysis to cyclopentanol was the main reaction pathway above 200 degrees C. The hydrogenation rate was doubled in an acidic solution (pH = 3) as compared to that at a pH 6. The spent catalyst was regenerated and reused in subsequent catalytic runs.
