我国拥有丰富的秸秆类生物质资源，秸秆通过热化学液化可得到液化产物（生物基多元醇），利用该生物基多元醇可以制备聚氨酯等多种化工产品，发展和利用生物基多元醇对缓解石油供需紧张和环境污染问题具有重要意义。然而，生物基多元醇中含有大量的羰基化合物，对所制备的材料性能有较大的影响，必须对生物基多元醇进行催化加氢精制以提高产品的性能。本课题拟通过化学还原法制备一系列的Co(Ni)-Cu-B非晶态催化剂，考察催化剂分别对乙酰丙酸丁酯、糠醛、乙酸等模型化合物和玉米秸秆制备的生物基多元醇加氢精制的催化反应性能。利用先进的分析测试手段以及原位和连续流动状态下的程序升温测试技术，探索生物基多元醇中羰基化合物催化加氢制醇的催化反应机理；采用集总的方法，建立生物基多元醇催化加氢的集总动力学模型,为生物质制备高品质化工产品的研究提供理论指导，具有重要的理论意义和应用价值。

China has abundant resources of biomass which can be converted to bio-based polyols through liquefaction process. It is very important to develop and utilize the bio-based polyols for alleviating the increasing shortage of energy supply and reducing the environment pollutions. However, the bio-based polyols contain many carbonyl compounds including furans, phenols, aldehydes, ketones, etc., which can greatly influence the properties of the polyurethane. It is very necessary to selectively reduce carboxide from the bio-based polyols via the hydrogenation to improve the quality of the upgraded bio-based polyols. In this study, Ni, Co and Cu were selected as active components to prepare a serial of Co-Cu-B, Co(Ni)-Cu-B, Ni-Cu-B, Co-Ni-Cu-B amorphous catalysts by chemical reduction method, and their catalytic activities were tested using bio-based polyol of cornstalk and its model compounds such as butyl levulinate, furfural, acetic acid, etc. The hydrogenation mechanism of carbonyl compounds to alcohols from bio-based polyol of cornstalk was studied by the modern characterization techniques. Moreover, the lumping kinetic model of hydrogenation of bio-based polyol was developed, which will provide guidance for high value-added products preparation from lignocellulose. The project has great theoretical value and application value in remitting the shortage of petroleum resources in China.
