Closing the CO2 Loop: From Capture to Utilization

减少温室气体排放是最重要的国际优先事项之一。在过去的15年里，我们的团队通过一系列创新的专有材料在二氧化碳吸附领域做出了开创性的贡献。在我们最近的NSERC发现资助期间，我们在碳捕获、氢储存、催化和材料设计领域取得了突出进展。我们开发了一系列强大的、高容量的含胺二氧化碳吸附剂并获得了专利，并研究了它们在蒸汽存在下的水热稳定性，以及它们在工业气体（如湿度、O2、H2S和SO2）中普遍存在的杂质存在下的稳定性。特别是，我们发现了水蒸气的稳定作用，并申请了专利。这无疑是这一领域最重要的发现。我们还开发了疏水性聚乙烯亚胺浸渍材料，在高（100%）和超低（400 ppm） CO2浓度下，其胺效率都是有史以来最高的。****同时，我们设计了独特的氮掺杂微孔碳，具有有史以来最高的CO2容量和出色的H2存储能力。除了低温CO2捕获外，我们还开发了用于高温CO2分离的高稳定的cao基材料。我们亦在污水处理，特别是选择性去除重金属方面，进行了广泛的工作。****我们的工作一直是创新的、鼓舞人心的和有影响力的****在目前的提案中，我们将在碳捕获方面建立自己的优势，并将我们的努力扩大到新的领域，即(i)二氧化碳和生物质利用，用于制造高附加值化学品和可再生燃料，（ii）开发低成本的硅基吸附剂，用于去除挥发性有机化合物和控制化学和油漆工业的空气排放，（iii）利用纳米技术开发一种新的可重复使用的靶向给药系统。****长期目标是(i)与加拿大工业伙伴合作，将我们的二氧化碳捕集技术商业化。我们的主要目标是利用超快速吸附-解吸循环和一步沼气升级为可再生天然气，同时去除水分、H2S和CO2， （ii）开发具有竞争力的催化剂，实现经济上可行的CO2功能化，（iii）设计具有更低能源需求和更低运营成本的新型VOC吸附剂，以及（iv）证明一种新型、可回收的靶向药物输送系统的可行性。****所请求的发现补助金将在加拿大一些最优先领域培训各级年轻研究人员。HQP将在涉及材料科学、化学、化学和环境工程的独特多学科环境中接受最高质量的培训。在处理及时和具有挑战性的问题时，他们将接受有关大量最先进设备*****的广泛培训

Greenhouse gas mitigation is one of the highest international priorities. For over 15 years, our group made seminal contributions in the area of CO2 capture by adsorption over a family of innovative proprietary materials. During our most recent NSERC Discovery Grant, we made outstanding progress in the fields of carbon capture, hydrogen storage, catalysis and materials design. We developed and patented a family of robust, high capacity amine-containing CO2 adsorbents, and investigated their hydrothermal stability in the presence of steam as well as their stability in the presence of ubiquitous impurities in industrial gases such as humidity, O2, H2S and SO2. In particular, we discovered and patented the stabilizing effect of water vapour. This is undoubtedly the most important finding in this field. We also developed hydrophobic polyethylenimine-impregnated materials with the highest ever amine efficiency both at high (100%) and ultra-low (400 ppm) CO2 concentration.**** In parallel, we designed unique nitrogen-doped microporous carbons with the highest ever CO2 capacity and excellent H2 storage. In addition to low temperature CO2 capture, we developed highly stable CaO-based materials for high temperature CO2 separation. We also carried out extensive work on the treatment of wastewater, particularly the selective removal of heavy metals.**** Our work has been innovative, inspiring and influential**** In the current proposal, we will build on our own strength in carbon capture and expand our effort to new areas, namely (i) CO2 and biomass utilization for the manufacture of high value-added chemicals and renewable fuels, (ii) development of lower cost silica-based adsorbents for the removal of volatile organic compounds and air emissions control in the chemical and paint industry, and (iii) development of a novel reusable targeted drug delivery system using nanotechnology.**** The long-term objectives are (i) to commercialize our CO2 capture technology in collaboration with Canadian industrial partners. Flue gas treatment using ultra-rapid adsorption-desorption cycling and singe-step biogas upgrading into renewable natural gas, based on simultaneous removal of moisture, H2S and CO2 are our main targets, (ii) to develop competitive catalysts for economically viable CO2 functionalization, (iii) to design novel VOC adsorbents with lower energy requirements and lower operating costs, and (iv) to demonstrate the feasibility of a novel, recoverable targeted drug delivery system.**** The requested discovery grant will train young researchers at all levels in some of Canada's top priority areas. HQP will receive the highest quality training in a uniquely multidisciplinary environment involving materials science, chemistry, chemical and environmental engineering. While working on timely and challenging issues, they will receive extensive training on a large collection of state-of-the-art equipment*****
