Pyrolytic conversion of a large variety of agricultural and forestry residues into liquid bio-oils and solid biochar is a very attractive technology that has been perfected and scaled up in our laboratories of the Institute for Chemicals and Fuels from Alternative Resources (ICFAR). Bio-oils offer a large variety of alternative applications, including their use as fuels, pesticides, insecticides, flavors, and pharmaceuticals. However, their characteristics vary greatly as a function of the original feedstock and of the operating conditions and, typically, they cannot be immediately utilized without further processing and upgrading. Similarly, the pyrolytic bio-char needs to be upgraded to take full advantage of its characteristics and maximize its value. Therefore, building on previous experience and track record, the main objectives of the proposed research program include (a) continuous improvements of the fluid bed technology to allow the efficient processing of an ever expanding array of materials that are carefully selected to avoid competition with food or other more efficient biological conversion processes (agricultural and forestry residues, co-products of the food processing industry, and byproducts generated in biological conversion processes), and (b) the development of upgrading technologies for bio-oils and bio-chars produced from different residues to make them suitable for integration into the existing markets for conventional fossil fuels and chemicals as individual products or as blends. These objectives will be achieved by undertaking new projects, all involving graduate students, on (1) the improvement of the solid feeders for fluid bed pyrolyzers to handle cohesive and fibrous biomass materials; (2) investigating fractional condensation to achieve a primary separation of fractions of bio-oil that could then separately utilized or upgraded using appropriate reaction pathways; (3) studying physical and chemical upgrading of bio-chars; and (4) conducting a comprehensive research program on bio-oil catalytic and thermal upgrading, including the potential and synergies derived from the co-processing (co-pyrolysis) of biomass/bio-oils and of Canadian heavy hydrocarbons (refinery heavy bottoms, heavy oils and bitumens).

将各种农业和林业残留物转化为液体生物油和固体生物炭是一种非常有吸引力的技术，它在我们的化学和燃料研究所的实验室中已经完善并扩展了替代资源（ICFAR）的化学和燃料研究所。 生物油提供多种替代应用，包括用作燃料，农药，杀虫剂，口味和药物。 但是，它们的特性随着原始原料和操作条件的函数而差异很大，通常，如果没有进一步的处理和升级，就无法立即使用它们。 同样，需要升级热解生物炭，以充分利用其特征并最大化其价值。因此，基于先前的经验和往绩记录，拟议的研究计划的主要目标包括（a）持续改进流体床技术，以便有效地处理一系列不断扩展的材料，这些材料被精心挑选，以避免与食物或其他更有效的生物学转化过程（农业和林业生物待遇），生物处理工业的生成繁殖及其生产的生产量，并构成了生产的生产，该材料的生成率是生产的生产，并构成了生产量的生产。来自不同残基生产的生物油和生物染料的升级技术使其适合将传统化石燃料和化学物质作为单个产品或混合物集成到现有市场中。 这些目标将通过（1）改善流体床毒脂式固体饲养器来处理凝聚力和纤维纤维生物量材料，从而实现这些目标； （2）研究分数凝结以实现生物油的一级分离，然后可以使用适当的反应途径分别利用或升级； （3）研究生物柜的物理和化学升级； （4）开展一项有关生物油催化和热升级的综合研究计划，包括源自生物质/生物油和加拿大重型碳氢化合物（炼油厂重的底部，重油，重油和杀油）的共处理（共溶解）的潜力和协同作用。
