基于产物特征的纤维素和聚丙烯共热解相互作用机制和MCM-41催化机理研究

生物质能可作为一种清洁替代燃料，利用液化技术将低品位的固体生物质转化为高品位的液体燃料或化学品，已成为生物质能高效利用的方式之一。生物质是缺氢基质，废塑料可为生物质的油品改进提供现成可用的更便宜的富氢基质。因此，研究生物质和塑料的共热解相互机理具有重要意义；本项目开展纤维素，半纤维素、木质素和聚丙烯的共热解机理研究，通过不同停留时间来开展一次反应和二次反应过程的产物特性，尤其H,O的转化规律，并构建相应的多尺度二元热解模型，在此基础上，开展介孔全硅分子筛MCM-41催化剂对生物质与塑料共裂解催化反应机理，以实现对热解产物组分的调控。通过本项目的研究，发表SCI文章4～5篇，国内核心期刊2～3篇，申请专利2-3项，协助培养博士生1-2人和硕士生1-2人。

As a clean alternative fuel of fossil fuel, the liquefied technology of biomass become of the efficient ways of biomass utilization. The high content of hydrogen in the plastic wastes can compensation for the lack of H in the biomass which can improve the quality of pyrolysis oil. Therefore, it is valuable to studied the synergistic effect during the co-pyrolysis of cellulose， hemicellulose, lignin and PP with/without a all-silica MCM-41. The characteristics of pyrolysis product of cellulose， hemicellulose, ligninand PP will be investigated during the primary and secondary thermal degradation by the well-designed sampling system and reactor, and the effect factors will be obtained by the process. And the mechanism of catalytic pyrolysis of cellulose and PP will also be studied to control the transfer of H,O during pyrolysis process. And a multi-scale modeling of cellulose and PP co-pyrolysis process will be developed and the main reaction mechanism of hydrocarbon and alcohols products will be concluded for the catalyst. For the outcomes of this project, 6～8 papers will be published, including 4~5 SCI and2-3 EI indexed paper. And also 1~2Ph.d and 1-2 master student can be graduated.
