The increasing concern about the future availability of petroleum as the main source of liquid fuels and chemicals has prompted the search for alternatives. Attention is turning to the conversion of low-value streams from biomass operations, and oil and gas processes, to higher-value products. Plant biomass-derived fuels and chemicals are currently the only carbon-neutral, renewable alternative to fossil fuels. Renewable gasoline/diesel fuels are the transportation fuels of the future. Thus, the use of low/negative value wastes, produced from the industrial processing of renewable and non-renewable raw materials, deserve acute attention. In Canada and northern BC in particular, the generation of higher value products from low value "renewables" from wood processing (e.g. lignin, biomass residues) and "non-renewables" from oil refining (e.g. FCC bottoms, petroleum sludge) is key for the continued economic viability of these important industries. The long-term goal of this Discovery Grant is to develop suitable strategies to generate high value-added products directly from low/negative value waste streams and resources.  Two approaches will be studied. One will investigate new upgrading routes to produce unprecedentedly high yields of infrastructure compatible fuels (e.g. hydrocarbons) and high-value "non-fuel" specialty chemicals (e.g. flavors, cosmetics) from the selective conversion of these low-cost materials. A key objective will be to use a single reactor and lean in-situ hydrogen conditions to maximize safety and minimize economic costs. Two laboratory reactors (fixed-bed, stirred tank) operating separately or in tandem will be used to study the performance of selected catalysts. Compatible waste streams will be co-processed to potentially improve the selectivity and product yield. For the promising route(s), the kinetics, mechanism(s), modeling, and reaction conditions in terms of conversion, product yield and selectivity will be determined. The other approach will study these waste streams (or portions thereof) for the production of useful advanced materials via granulation, activation and other techniques. For example, their use as sources of low-cost biochars and adsorbents for pollutant removal from industrial waste waters will be investigated. In each strategy, essential structure-property relationships will be elucidated via appropriate characterization studies, with practical applications and economic benefits identified for the most promising products and processes. This Discovery Grant program is well suited to train Highly Qualified Personnel (HQP) for the emerging job markets in bio-refining and waste upgrading. The proposed work will lead to several benefits, including: pollution reduction created by industrial wastes and residues, and valorization of forestry and petroleum byproducts; all with significantly positive economic and environmental impacts.

对石油作为液体燃料和化学品的主要来源的未来可得性的日益关注促使人们寻找替代品。人们的注意力正转向将生物质作业以及石油和天然气加工的低价值流转化为高价值产品。植物生物质衍生燃料和化学品是目前唯一的碳中性，可再生的化石燃料替代品。可再生汽油/柴油燃料是未来的运输燃料。因此，对可再生和不可再生原材料的工业加工所产生的低/负价值废物的利用值得高度重视。在加拿大，特别是在不列颠哥伦比亚省北方，从木材加工的低价值“可再生能源”（如木质素、生物质残渣）和炼油的“不可再生能源”（如催化裂化残渣、石油污泥）中生产高价值产品是这些重要行业持续经济可行性的关键。这项研究资助计划的长远目标，是发展合适的策略，直接从低/负价值的废物流和资源中生产高增值产品。我们会研究两种方法。其中一个将研究新的升级路线，以生产前所未有的高产率的基础设施兼容的燃料（如碳氢化合物）和高价值的“非燃料”特种化学品（如香料，化妆品）从这些低成本材料的选择性转化。一个关键的目标将是使用一个单一的反应堆和现场贫氢条件，以最大限度地提高安全性和最大限度地降低经济成本。两个实验室反应器（固定床，搅拌罐）单独或串联操作将用于研究所选催化剂的性能。将对相容的废物流进行共处理，以潜在地提高选择性和产品收率。对于有前景的路线，将确定动力学、机理、建模和转化率、产物产率和选择性方面的反应条件。另一种方法将研究这些废物流（或其部分），通过造粒，活化和其他技术生产有用的先进材料。例如，将研究它们作为低成本生物炭和吸附剂的用途，以从工业废水沃茨中去除污染物。在每种策略中，将通过适当的表征研究阐明基本的结构-性质关系，并为最有前途的产品和工艺确定实际应用和经济效益。这项发现补助金计划非常适合为生物精炼和废物升级的新兴就业市场培训高素质人员（HQP）。拟议的工作将带来几个好处，包括：减少工业废物和残留物造成的污染，以及森林和石油副产品的价格稳定;所有这些都具有显著的积极经济和环境影响。
