The Forestry Products Association of Canada (FPAC) has identified co-production of new, high value bio-energy, bio-chemicals, and bio-materials as a priority for Canadian forestry. To develop such processes, and the mass transfer models, kinetic models, and economic evaluations needed to support reliable scale-up, the proposed research program will be divided into three focus areas: FA1) hemicellulose recovery through hydrolysis, FA2) extractives recovery for use as valuable products, and FA3) chemical conversion of biomass derivatives. Because cellulosic biomass at approximately $60/dry ton is equivalent in energy cost to petroleum at $20/barrel, the economic obstacle to commercialization is the high cost of biomass conversion, as has been pointed out in several studies. Therefore, as part of FA1 a detailed characterization of Canada's primary biomass resource, softwoods, will be performed using a unique fixed bed flowthrough reactor (FBFR) in order to optimize hemicellulose hydrolysis and its integration with chemical conversion. FA1 will also optimize the application of hemicellulose polysaccharides as strength additives in BC's Northern bleached softwood kraft pulp. In addition, FA2 activities will adapt the techniques for biomass hydrolysis to extract valuable nutraceuticals and pharmaceuticals, beta-thujaplicin and plicatic acid, from Western red cedar. Extraction studies will be accompanied by development of chromatographic purification technology for beta-thujaplicin and plicatic acid. FA3 will examine two promising routes to platform chemicals: oxidation of pyrolysis oil derived from biomass and catalytic hydrogenation of biomass polysaccharides. Proposed FA3 research includes groundbreaking studies scrutinizing the impact of other biomass components on these thermochemical conversions. Novel and standard reactors will be combined with gas and liquid chromatography to support all of these activities. Catalyst features will be measured using instrumentation within the UBC Applied Catalysis Research facility. For each FA, process models and techno-economic analyses will be developed through computer simulations to accelerate optimization, determine commercial viability, and identify process improvements with the greatest impact. Ultimately, this research program will provide vital fundamental insights into biorefining kinetics and transport phenomena to guide applications and facilitate technology advances, establish new revenue streams and employment opportunities for Canada's forestry industry, train much-needed HQP, and contribute to the socio-economic health of rural communities.

加拿大林业产品协会（FPAC）已将新的，高价值的生物能源，生物化学和生物材料的共同生产确定为加拿大林业的优先事项。 为了开发此类过程，以及支持可靠规模的扩大所需的传质模型，动力学模型和经济评估，提议的研究计划将分为三个重点领域：FA1）通过水解，FA2的半纤维素恢复，FA2）挖掘恢复，将其用作有价值的产品，FA3）生物量衍生物的化学转化。 由于纤维素生物质约为60美元/干吨的纤维素对石油的能源成本为20美元/桶，因此商业化的经济障碍是生物质转化的高成本，正如多项研究中所指出的那样。 因此，作为FA1的一部分，将使用唯一的固定床流式反应器（FBFR）对加拿大主要的生物质资源（Softwoods）进行详细表征，以优化半纤维素水解及其与化学转化的整合。 FA1还将优化半纤维素多糖作为BC北部漂白软木牛皮纸浆中的强度添加剂。 此外，FA2活性将适应生物质水解的技术，以提取来自西部红雪松的有价值的营养素和药物，β-硫糖蛋白和镀酸。 提取研究将伴随着用于β-胰蛋白酶和卷酸的色谱纯化技术的发展。 FA3将检查到平台化学物质的两种有希望的途径：源自生物质和生物量多糖的催化氢化的热解油的氧化。拟议的FA3研究包括开创性的研究，审查了其他生物量成分对这些热化学转化的影响。 新型和标准反应堆将与气体和液相色谱法结合使用，以支持所有这些活动。 将使用UBC应用催化研究设施中的仪器来测量催化剂特征。 对于每个FA，将通过计算机模拟来制定过程模型和技术经济分析，以加速优化，确定商业生存能力以及确定最大影响的过程改进。 最终，该研究计划将为生物修复动力学和运输现象提供至关重要的基本见解，以指导应用程序并促进技术进步，为加拿大林业行业建立新的收入流和就业机会，培训急需的HQP，并为农村社区的社会经济健康做出贡献。
