| 英文摘要 | Efficient conversion of lignin to fine chemicals and biofuel become more and more attractive in biorefinery. in this work, we used a series of silica-alumina catalysts (i.e., sio2-al2o3, hy, h beta, and hzsm-5) to degrade lignin into arenes and phenols. the relationship between the catalyst structure and lignin depolymerization performance was investigated. the results showed that both acidity and pore size of the catalyst could influence the conversion of lignin. in the volatilizable product, phenols were identified as the main phenolic monomers via gas chromatography-mass spectrometer. sio2-al2o3 was the most efficient catalyst, giving 90.96% degree of conversion, 12.91% yield of phenols, and 2.41% yield of arenes in ethanol at 280 degrees c for 4 h. the fourier transform infrared spectroscopy and h-1 nuclear magnetic resonance spectroscopy analysis demonstrated that deoxygenation and alkylation occurred in this process. the effect of solvents was also investigated and the results showed that ethanol was the most efficient solvent. |
