Selective Hydrodeoxygenation of Guaiacol to Cyclohexane over Ru-Catalysts Based on MFI Nanosheets

Bio-oils derived from the pyrolysis of lignin-based biomass often contain a variety oxygenated compounds, which can compromise their usefulness as fuel. To improve quality bio-oil, catalytic hydrodeoxygenation (HDO) is crucial step that removes oxygen oil in form water. In this study, we showed MFI nanosheets are excellent supports for Ru-catalysts. We synthesized highly crystalline using simple hydrothermal seeding procedure; final material was obtained 56 h crystallization. investigated activity Ru supported on different materials. Our findings indicated hierarchical demonstrated HDO guaiacol. results Ru/ZNS-56 achieved nearly 100% selectivity towards cyclohexane under mild conditions (200 °C, 50 bar H2, 1 h).
