Novel Solid Materials and Processes for CO2 Capture from Cogeneration Flue Gas

能源部门二氧化碳排放的一个重要来源（约90%）是天然气热电联产（热电联产）的有效利用所产生的电力和蒸汽。目前从热电联产烟气中大规模捕集二氧化碳的技术缺乏吸引力，因为二氧化碳浓度相对较低（4- 6%），导致运营和资本成本高。热电联产烟气的独特成分需要创新的材料和工艺开发战略。与加拿大自然资源有限公司（CNRL）、森科尔能源公司（Suncor Energy）、InnoTech Alberta和Fluor Canada Ltd.合作的根本目标是开发一种基于吸附的技术，从热电联产烟气中捕获二氧化碳，并降低其风险。通过这一联盟，加拿大一些最大的能源公司将合作开发减少二氧化碳排放的技术解决方案。将通过结合实验和分子模拟来开发三类固体吸附剂，同时解决工艺强化和规模扩大的挑战。迄今为止，对热电联产烟气CO2吸附工艺开发的综合研究尚未考虑杂质、放大和工艺优化的影响。这项研究将从合成新材料和实验规模的研究中获得基础知识，以利用最佳的吸附剂进行长期的中试规模的装置。这项研究开发的创新技术将很容易转化为商业化，从而促进环境友好型能源生产。该研究的结果有助于能源部门的脱碳，并与加拿大到2050年实现净零排放的愿景完全一致。革新性技术的创造将使二氧化碳捕获过程在经济上可行。该研究将帮助培养18名高素质人才（HQP），其中包括3名pdf， 4名博士，3名msc和8名本科生，具有加拿大自然资源和能源部门温室气体控制技术的专业知识。

A significant (>90%) source of CO2 emissions in the energy sector is power and steam production from the efficient use of combined heat and power (cogeneration) from natural gas. Current technologies for large-scale CO2 capture from cogeneration flue gas are unattractive due to the relatively low (4-6 %) concentration of CO2, leading to high operating and capital costs. The unique composition of cogeneration flue gas requires innovative materials and process development strategies. The underlying goal of this partnership with Canadian Natural Resources Limited (CNRL), Suncor Energy, InnoTech Alberta, and Fluor Canada Ltd. is the development and de-risking of an adsorption-based technology to capture CO2 from cogeneration flue gas. Through this alliance, some of the largest energy companies in Canada will collaborate to develop technology solutions to reduce their CO2 emissions. Three classes of solid sorbents will be developed by combining experimentation and molecular simulations while addressing process intensification and scale-up challenges. Thus far, no comprehensive study on the development of CO2 adsorption processes from cogeneration flue gas has considered the effects of impurities, scale-up, and process optimization. This research will generate fundamental knowledge from synthesizing novel materials and bench-scale studies to utilize the best sorbents for a long-term, pilot-scale unit. The innovative technologies developed from this study will be readily transferable for commercialization, thereby facilitating environmentally friendly energy production. The study's outcome contributes to the decarbonization of the energy sector and is well-aligned with Canada's vision of net-zero emissions by 2050. The creation of transformative know-how will make the CO2 capture process economically feasible. The research will help train 18 highly qualified personnel (HQP), including 3 PDFs, 4 PhDs, 3 MScs, and 8 Undergraduates, with expertise in GHG control technologies in Canada's natural resource and energy sectors.
