Cellulosic biomass is abundant and inexpensive, and is generated at large quantities in the agricultural and forestry sectors as residues (cornstalks, wheat straw, sawdust, bark, etc.). Glucose is the main building block of cellulosic biomass, and it can be readily and inexpensively produced from cellulosic biomass via acid or enzymatic hydrolysis. Glucose can be converted into 5-hydroxymethyl-furfural (5-HMF) via catalytic de-hydration. 5-HMF is considered by the U.S. Department of Energy to be among the "top 10 list of bio-based chemicals" in terms of the market potential as it is a versatile intermediate platform precursor for the syntheses of a wide range of biofuels and bio-based chemicals. Compared with other bio-platform chemicals, such as bio-ethanol and levulinic acid, 5-HMF is particularly promising in terms of carbon utilization efficiency as it retains all six carbon-atoms of glucose. The long-term goal of this research program is to develop novel 5-HMF-platform biorefinery for conversion of cellulosic biomass into renewable fuels and chemicals. As short-term objectives, my research efforts in the next five years will be centered on developing novel continuous processes and heterogeneous catalysts for conversion of glucose into biofuels (renewable gasoline and aviation biofuels) and bio-based chemicals, specifically (1) to develop highly efficient continuous processes and heterogeneous catalysts to convert glucose to 5-HMF; (2) to produce renewable gasoline and aviation biofuels from 5-HMF in a continuous reactor; (3) to transform 5-HMF into 2,5-dihydroxymethyl furan and 2,5-furandicarboxylic acid and produce biopolymers. **In this project, a novel continuous process using heterogeneous catalysts will be developed and used for cost-effective conversion of glucose to 5-HMF. 5-HMF will be further catalytically converted to 2,5-dimethylfuran (DMF) and 2,5-dimethyltetrahydrofuran (DMTF). DMF and DMTF can be renewable gasoline with a much higher energy content than5-HMF. With the continuous process and heterogeneous catalysts, 5-HMF will also be converted to 2,5-dihydroxymethyl furan and 2,5-furandicarboxylic acid (FDCA) for production of biopolymers such as bio-based polyethylene terephthalate (PET) by replacing terephthalic acid with FDCA. Furthermore, as an aromatic aldehyde compound, 5-HMF will be transformed to a coupled product - C12 furoin via self-benzoin condensation and then to C12 hydrocarbons as a potential aviation biofuel by hydrogenation. The glucose-to-5-HMF processes reported so far in the literature are mostly lab-scale batch systems with homogeneous catalysts. In order to produce 5-HMF more economically on a large scale, developing continuous processes and highly active heterogeneous catalysts (to ease catalyst recycling) is the key. The success of this NSERC DG research program could enhance Canada's economic sustainability in a long term, by creating additional profit streams to the Canadian forest and agricultural sectors and offering renewable chemicals/materials to the Canadian chemical industries. Moreover, this program is expected to train more than 10 highly qualified personnel in a broad area of biorefinery - an area of great significance to Canada's bioeconomy development.

纤维素生物量丰富且廉价，并且在农业和林业领域大量产生，作为残留物（玉米虫，小麦稻草，木屑，树皮等）。葡萄糖是纤维素生物量的主要组成部分，可以通过酸或酶水解从纤维素生物量产生容易，廉价地产生。葡萄糖可以通过催化脱水转化为5-羟甲基曲面（5-HMF）。在市场潜力方面，美国能源部认为5-HMF是“基于生物的化学物质的十大清单”之一，因为它是一种多功能的中间平台前体，用于广泛的生物燃料和基于生物的化学品的合成。与其他生物平台化学物质（例如生物乙醇和脱免除酸酸）相比，在碳利用效率方面，5-HMF尤其有前途，因为它保留了所有六种六碳原子葡萄糖。该研究计划的长期目标是开发新型的5-HMF平台生物融资，以将纤维素生物量转化为可再生燃料和化学物质。作为短期目标，我未来五年的研究工作将集中在开发新型的连续过程和异质催化剂中，以将葡萄糖转化为生物燃料（可再生汽油和航空生物燃料）和基于生物的化学物质（特别是）（1），以高效的连续过程和高效的连续过程和异型式抗体蛋白蛋白（1），使其转化为5-HMF crows glucf to 5-HMF; （2）在连续反应堆中从5-HMF产生可再生的汽油和航空生物燃料； （3）将5-HMF转化为2,5-二羟基甲基呋喃和2,5-二甲基二羧酸并产生生物聚合物。 **在这个项目中，将开发使用异质催化剂的新型连续过程，并用于将葡萄糖转化为5-HMF。 5-HMF将进一步催化转化为2,5-二甲基富兰（DMF）和2,5-二甲基四氢呋喃（DMTF）。 DMF和DMTF可以是可再生的汽油，其能量含量高于5-HMF。借助连续过程和异质催化剂，5-HMF也将转换为2,5-二羟基甲基呋喃和2,5-二甲基羧酸（FDCA），用于生产生物聚合物，例如通过用FDCA替换生物基苯乙酸苯二甲酸酯（PET），例如基于生物的聚乙二醇Tereyphthalate（PET）。此外，作为一种芳香醛化合物，5-HMF将通过自苯并凝结转换为耦合产物-c12 furoin，然后转化为C12碳氢化合物作为氢的潜在航空生物燃料。到目前为止，文献中报道的葡萄糖至5-HMF过程主要是具有均匀催化剂的实验室规模批量系统。为了大规模地产生5-HMF，开发连续过程和高度活跃的异质催化剂（以减轻催化剂回收）是关键。该NSERC DG研究计划的成功可以长期增强加拿大的经济可持续性，通过为加拿大森林和农业领域创造更多的利润来，并向加拿大化学工业提供可再生的化学药品/材料。此外，该计划预计将在一个广阔的生物融资领域培训10名高素质的人员，这是对加拿大生物经济发展具有重要意义的领域。
