Chemical looping systems towards a low carbon future

要实现2摄氏度的升温目标和低碳的未来，需要各种技术的进步。为了抵消传统的以化石燃料为基础的能源生产，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中。提出了一种通过生物质利用与化学环系统耦合生产低碳能源的新途径。生物质是一种丰富的可再生原料，是碳中和能源的潜在生产者。加拿大是欧洲木屑颗粒的主要出口国。开发充分利用生物质的技术可以增强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过程的灵活性。这是通过化学环系统实现的，它允许亚反应和化学中间体的去耦以及产物的固有分离。例如，化学环燃烧是一种间接燃烧气体燃料的方法，它利用金属氧化物作为氧气来源，并使二氧化碳与烟气的其余部分分离。开发低碳能源生产系统需要了解基本的化学反应工程与工艺设计相结合。在这个项目中，根据通过过去的项目和目前的中试规模概念测试机会获得的专业知识，研究了各种化学环系统。******上述方法的新颖性在于将基本反应建模与反应堆设计和过程建模相结合，以便集成组件并严格检查可以促进低碳能源生产系统发展的过程。******这一建议代表了培养高素质人才的非凡前景。Ellis实验室、UBC校园（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）提供的设施都可以直接向学员开放。创造一个独特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，他们将在加拿大和国际上对低碳未来产生重大影响。

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.
