| 摘 要： | 棉秆直接脱氧液化制备出富含酚类化合物的生物油,将该生物油进行精馏,收集180～260℃的馏分(酚类化合物GC含量高达78.84%),得率约为45%。用1%NaOH碱洗分离油相与水相,水相用有机膨润土吸附和有机溶剂萃取分离,通过GC、GC-MS分析。结果表明,有机膨润土吸附的酚类化合物GC含量为79.13%,有机溶剂萃取分离法可获取纯度较高的酚类化合物,萃取后溶剂中酚类化合物GC含量可高达93.89%,纯度可达93.63%。

| Abstract: | The bio-petroleum obtained from cotton stalk by deoxy-liquefaction which is rich in phenol derivatives was rectified and the fraction of 180-260℃ was collected, in which the GC content of phenolic compounds was as high as 78.84%, the yield was about 45%. After the fraction was bathed with NaOH solution, the oil phase and water phase were separated. The phenolic compounds in water phase were separated by adsorption with the organobentonite and extraction with the organic solvent, and analyzed by GC and GC-MS. The results showed that high purity of phenolic compounds were obtained by organic solvent extraction method and the relative content in organic solvent and the purity after separation were up to 93.89% and 93.63%, respectively. |
