Commitment to the 2C warming scenario and a low carbon future demands the advancement of various technologies. In order to offset the conventional fossil-fuel-based energy production, low carbon energy technology must be included in the mix of renewables and energy conversion schemes. A novel approach to producing low carbon energy through coupling biomass utilization and chemical looping systems is proposed. Biomass, an abundant and renewable source of feedstock, is a potential producer of carbon-neutral energy. Canada is a major exporter of wood pellets to Europe. Developing technologies to fully utilize biomass strengthens economic and social values in Canada. ******The seasonability and variability of biomass as feedstock demands process flexibility. This is attained through chemical looping systems, which allow decouping of subreactions and chemical intermediates and inherent separations of products. For example, chemical looping combustion, an indirect combustion of gaseous fuel, applies metal oxides as a source of oxygen, and allows separation of CO2 from the rest of flue gas. Developing a low carbon energy production system requires understanding fundamental chemical reaction engineering combined with process design. In this program, various chemical looping systems are investigated, based on the expertise gained through past projects and current opportunities for pilot-scale concept testing. ******The novelty of the approaches noted above resides in coupling fundamental reaction modeling with reactor design and process modeling, in order to integrate components and critically examine processes which can advance the development of low carbon energy production systems. ******This proposal represents an exceptional prospect for training highly qualified personnel. Facilities available through the Ellis lab, the UBC campus (through the Campus as a Living Lab, and Bioenergy Research and Demonstration Facility), and the Technology Commercialization and Innovation Centre (through the Carbon Capture and Conversion Institute) are all directly accessible to the trainees, creating a unique and highly relevant training opportunity to nurture our next generation of engineers and leaders who will make considerable impact in Canada and internationally towards a low carbon future.

致力于2 ℃的变暖情景和低碳未来需要各种技术的进步。为了抵消传统的化石燃料能源生产，低碳能源技术必须包括在可再生能源和能源转换计划的组合。提出了一种耦合生物质利用和化学循环系统生产低碳能源的新途径。生物质是一种丰富的可再生原料来源，是碳中和能源的潜在生产者。加拿大是欧洲木质颗粒的主要出口国。开发充分利用生物质的技术加强了加拿大的经济和社会价值。** 生物质作为原料的季节性和可变性要求工艺灵活性。这是通过化学循环系统实现的，该系统允许子反应和化学中间体的分离以及产品的固有分离。例如，化学链燃烧，气体燃料的间接燃烧，应用金属氧化物作为氧源，并允许从烟道气的其余部分中分离CO2。开发低碳能源生产系统需要了解基础化学反应工程与工艺设计相结合。在这个程序中，各种化学循环系统进行了调查，通过过去的项目和目前的机会中试规模的概念测试获得的专业知识的基础上。** 上述方法的新奇在于将基本反应建模与反应器设计和过程建模相结合，以便整合组件并严格检查可以推进低碳能源生产系统开发的过程。** 本建议代表了培训高素质人员的特殊前景。通过埃利斯实验室，UBC校园提供的设施（通过校园作为生活实验室，生物能源研究和示范设施），以及技术商业化和创新中心（通过碳捕获和转化研究所）都可直接供学员使用，创造一个独特的和高度相关的培训机会，培养我们的下一代工程师和领导者谁将作出相当大的影响，加拿大和国际上走向低碳的未来。
