This study focused on the hydrodeoxygenation(HDO) of guaiacol over Ni2P catalysts with different reaction temperature and pressure. The Ni2P catalysts showed a good and stable activity with a guaiacol conversion over 90% at 523-573K and 1 or 8atm, and LHSV of 2.0 h-1. The major products were cyclohexane, benzene, anisole and phenol. Two different reaction pathways were confirmed; direct deoxygenation was dominant to give benzene at 1 atm and prehydrogenation followed by deoxygenation was preferred to give cyclohexane at 8 atm. The XAFS analysis revealed that the active site of Ni2P catalysts is slightly bound by oxygen during the reaction. |
