The production of deoxygenated compounds was observed during the batch reduction of eugenol with H-2 (room-temperature-equivalent pressure = 50 bar) over Ru/CaCO3 at 250 degrees C, and the yields of compounds with no oxygen atoms (0-O) and one oxygen atom (1-O) were determined as 25.5 and 48.2%, respectively. X-ray photoelectron spectroscopy revealed that the improved hydrodeoxygenation activity could be ascribed to the increased electron density of catalytically active Ru species because of electron donation from the support.
