中文摘要： 生物油中高含量的重质组分具有难挥发、易老化和不利于燃烧等特性，严重影响了生物油的品质和产业化进程。针对生物油中重质组分分离难度大、分离方法精制能量损失大的问题，本项目拟根据不同重质组分的结构特征，分步采用酸性离子液体[Cn(mim)m]Y催化酸解低聚糖类物质，采用酸性氧化物(TiO2或SBA)固载的纳米金属粒子（Pd或Ru）催化氢解热解木质素类物质；通过考查降解反应机理及催化剂构效关系、优化反应的选择性和整合精制加工技术等环节的实施，在生物油真实体系中将低聚物高效转化成小分子化合物，从而实现生物油品质的提升。通过本项目的研究不仅可以深入认识生物油中重质组分的形态和特性，还可以弄清其转化机理及影响因素，从而为生物油精制加工积累数据信息和技术经验，同时也可为生物质资源的转化与利用提供依据。

英文摘要： Bio-oil derived from biomass is sustainable and environmental protection. However, a lot of oligomers remain in bio-oil, and they are nonvolatile, easy to polymerize, and harmful to bio-oil burning, so that the quality of bio-oil were impaired very much. In our project, the acidity ionic liquid ( [Cn(mim)m]Y ) and metal nanoparticles(e.g. Ru-SBA) would be applied in the conversion of these oligomers. With the following research contents proceeded, such as the study of the mechanism on the acidic hydrolysis and hydroprocess, the analysis of influencing factors, the optimization of the reaction selectivity and the integration of upgrading technology, the oligomers would be efficiently converted into little molecule compounds, and the properties of crude bio-oil would be improved. With this research project preformed, we could make clear the characteristic of the oligomers, and understand fully the conversion mechanisms and their corresponding influencing factors. And then, a lot of technologies and experience would be accumulated for the bio-oil upgrading, and so far as to afford the reference to the conversion and utilization of biomass resource.
