Integrated Biorefinery Conversion Crop Residues

项目摘要

The long-term goal of the proposed research program is to develop an integrated biorefinery for valorization of crop residues for bio-based polymer materials. The short-term objectives of this program are to (1) develop an efficient and cost-effective fractionation process for production of high purity cellulose and lignin from crop residues, (2) produce lignin-based UV-absorbers for coatings/plastics/sunscreens applications, and water absorbing polymers for soil water retention application, (3) develop new enzymes/bacterial strains for one-pot conversion of cellulose to fructose, (4) convert glucose/fructose into 2,5-Furandicarboxylic acid (FDCA), and produce polyethylene furanoate (PEF) as a green replacement for polyethylene terephthalate (PET) for packaging materials, and (5) demonstrate techno-economic feasibility of the proposed integrated biorefinery for production of the bio-based polymers from crop residues at industrial scale (50-100 tonnes/day). ******Canada is one of the largest agricultural producers and exporters in the world. According to Statistics Canada, over 65 million tonnes of major grains and oilseeds (wheat, canola seeds, corn, barley, soybeans and oats) were produced in 2011. If estimated based 1.5 tonne crop residue per tonne of grain production, the agriculture sector of Canada generates about 100 Mt crop residues annually. Crop residues are conventionally utilized for silage for livestock, fertilizer after composting, or solid fuel for heat or electricity generation. This DG proposal targets at an integrated biorefining approach to higher value utilization of two major components of crop residues, i.e., cellulose and lignin, for the production of bio-based polymers (i.e., lignin-based UV-absorbing, water-absorbing polymers, and cellulose-derived PEF for packaging materials). The world production of synthetic polymers (PE, PP, PVC, PS, PET, etc.) is immense, mainly from petroleum, reaching approx. 400 million tonnes per year with over $400 billion marker value. There is a pressing need for developing bio-based polymers in order to reduce the carbon footprints of the synthetic polymer production. Utilization of crop residues for high-value bio-polymers would thus strengthen Canada's leading position in bioeconomy, reduce its dependency on fossil resources (hence greenhouse gas emission), and create new profit streams and jobs for Canadian agriculture sector. ******This proposed program will contribute to training of 16 HQP, including 3 PhD students, 2 MESc and 8 MEng students, 1 postdoctoral fellow and 2 BESc undergraduate interns. The HQP will gain necessary expertise and skills for biorefinery and bioproducts development, e.g., lignocellulosic biomass fractionation, chemical modification of lignin, bio-based polymers characterization/applications, bioconversion of cellulose, catalytic conversion of carbohydrates, chemical reactors design, techno-economic analysis and scale-up of a process. **

拟议的研究计划的长期目标是开发一种用于生物基材料作物残基的综合生物填充物。该计划的短期目标是（1）开发一个有效且具有成本效益的分级过程，用于从作物残留物中生产高纯度纤维素和高纯度纤维素和木质素，（2）生产基于木质素的UV-紫外线剂，用于涂料/塑料/塑料/塑料/防晒霜应用，以及用于水的水的水疗法，以开发水的培养物，（3）培养物，（3））（3）培养物的相互作用（3） fructose, (4) convert glucose/fructose into 2,5-Furandicarboxylic acid (FDCA), and produce polyethylene furanoate (PEF) as a green replacement for polyethylene terephthalate (PET) for packaging materials, and (5) demonstrate techno-economic feasibility of the proposed integrated biorefinery for production of the bio-based polymers from crop residues at industrial scale （50-100吨/天）。 ******加拿大是世界上最大的农业生产商和出口商之一。根据加拿大统计局的数据，2011年生产了超过6500万吨的主要谷物和油料种子（小麦，低芥酸菜子种子，玉米，大麦，大豆和燕麦）。如果估计基于每吨谷物生产的1.5吨农作物残留物，则加拿大农业部门每年产生约100 mt的作物残留物。通常将农作物残留物用于青贮饲料，用于牲畜，堆肥后的肥料或固体燃料进行热或发电。该DG提案的目标是一种集成的生物修补方法，可用于对作物残基的两个主要成分（即纤维素和木质素）进行更高的价值利用，以生产基于生物的聚合物（即基于木质素的紫外线吸收，含水，吸收水分，吸收水分，以及用于包装材料）。合成聚合物（PE，PP，PVC，PS，PET等）的世界生产是巨大的，主要来自石油，大约达到。每年4亿吨，标记价值超过4亿美元。为了减少合成聚合物生产的碳足迹，需要开发基于生物的聚合物。因此，将作物残留物用于高value生物聚合物，从而增强了加拿大在生物经济中的领先地位，减少其对化石资源（因此温室气体排放）的依赖，并为加拿大农业部门创造新的利润流和工作。 ******该建议的计划将有助于对16个HQP进行培训，其中包括3名博士学位学生，2名MESC和8名Meng学生，1名博士后研究员和2名BESC本科实习生。 HQP将获得生物填充和生物生物生物开发的必要专业知识和技能，例如木质纤维素生物量分级，木质素的化学修饰，基于生物的聚合物表征/应用，纤维素的生物转化，纤维素的生物转化，碳水化合物的催化转化，碳水化合物的催化转化，化学反应者，化学反应者，技术经济学分析和量表分析。 **
