Abstract

Liquefaction of glucose into oil was examined in hot-compressed water at 300 °C and 30 or 60 min in a tumbling batch reactor. The effects of alkali (KHCO₃), a hydrogenating agent (HCO₂H), and a cobalt catalyst (Co₃O₄) were studied. Also the combinations of these additives were investigated. HCO₂H and KHCO₃ showed a positive effect on oil formation. Co₃O₄ was found to be an advantageous additive as well, increasing the oil formation from glucose, but the stability of this catalyst under reaction conditions was quite low.
