Description:
Catalytic performance of palladium supported on activated carbons and mesoporous aluminosilicate Al-SBA-15 were investigated at 300 °C under 8 MPa H 2 for hydrotreating of bio-oil model compounds, including phenol, anisole, and furfural. With Pd/C catalysts, phenol, anisole, and furfural have been mainly hydrogenated into cyclohexanol, 1-methoxycyclohexane and (tetrahydro-furan-2-yl)-methanol, respectively. Pd/C shows high hydrogenation activity, but poor deoxygenation ability. Differently, in the presence of Pd/Al-SBA-15, the main hydrotreating products of phenol, anisole, and furfural are cyclohexane, cyclohexane, and tetrahydropyran. The high hydrodeoxygenation activity of Pd/Al-SBA-15 is due to the synergistic effect of the noble metal, which has high hydrogenation ability and the support, which has acidic property, high surface area, and large pore size.
