| 为提高木质包装废弃物的利用率和附加值，拓宽木质资源的应用途径，研究了液固比（苯酚/纤维素）、催化剂含量、液化温度及反应时间对木质纤维素液化产物的影响。结果表明：随着液化温度的升高，木质纤维素液化物的残渣率先下降后增大，160 ℃时残渣率达到最低；随着催化剂含量的提高，木质纤维素液化的残渣率呈下降趋势，当催化剂含量低于6%时，残渣率下降较明显；液固比(苯酚/纤维素)小于5∶1时，木质纤维素液化的残渣率下降较明显；反应时间的增加对木质纤维素液化的残渣率的贡献率逐渐降低。 |
| 英文摘要: |
| In order to improve the utilization rate and added value of wood packaging waste and broaden the application field of wood resources, the influence of liquid-solid ratio, catalyst content, liquefaction temperature, and reaction time on lignocelluloses liquefaction product was studied. The result showed that with the raise of liquefaction temperature, the residual rate raises first and than drops with minimum value at 160 ℃; along with the catalyst content's raise, the rate of liquefaction of cellulosic residues is on the decline, which is more evident when the catalyst content drops below 6%; when the liquid solid ratio is less than 5∶1, the residual rate decreases obviously; the contribution of increasing reaction time to the residual rate reduces gradually. |
