| 中文摘要: |
| 木质素是一种绿色可再生的资源，是制备液体运输燃料的理想原料。本文研究了一种基于木质素制备液体运输燃料的方法。首先，我们选用K-OMS-2催化剂进行氧化反应测试，通过氧化木质素单体模型物获得芳香醛。木质素二聚体模型物（α-O-4结构木质素二聚体）氧化解聚后获得了65%产率的芳香醛。同时尝试氧化碱木素，产物检测中获得了香草醛，对羟基苯甲醛等化合物。其次通过芳香醛和丙酮发生Claisen-Schmidt 缩合反应增长碳链长度。最后通过芳烃加氢获得高品位的饱和烷烃燃料。 |

| Lignin is an abundant natural renewable resource, and it is an ideal feedstock for the production of liquid transportation fuels. In this work a method for the production of liquid transportation fuels from lignin was studied. First, lignin monomer model was oxidized to obtain aromatic aldehyde using K-OMS-2 as catalyst for oxidation reaction test. The lignin dimer model (α-O-4 structure lignin dimer) was oxidized and depolymerized to obtain the aromatic aldehyde in 65% yield. Meanwhile, by oxidizing alkali lignin, vanillin, p-hydroxybenzaldehyde and other aromatic aldehyde compounds can be detected from the product. Secondly, the length of the carbon chain was increased by Claisen-Schmidt condensation reaction of aromatic aldehydes and acetone. Finally, high-grade saturated alkane fuel was obtained by hydrogenation of aromatic hydrocarbons. |
