SusChEM: Integrated Materials and Process Systems Development for Sustainable Carbon Capture

提案号：1604890，PI: Hupp, j .标题：SusChEM：可持续碳捕获的集成材料和过程系统开发减缓大气中二氧化碳排放增加的一个受到严重关注的愿景是在大型点发电源（特别是发电厂）捕获二氧化碳并将其储存在稳定的地质构造中。在二氧化碳被隔离之前，必须将其与发电厂烟气中的其他物质分离，后者主要含有氮和水蒸气，以及其他微量气体。因此，在可再生能源技术继续在国家电网中安装的同时，从电厂烟气中经济地捕获和封存碳（CCS）可以成为缓解气候变化的中期解决方案的一部分。该项目将开发能够从烟气中去除二氧化碳的新型多孔材料，以及使用这些材料的工艺级技术，其长期目标是降低碳捕获的成本和能源需求。研究亦会有效地纳入教育及外展活动，包括在高度跨学科的环境中训练研究生，以帮助他们发展广阔的视野，培养良好的团队合作和沟通技巧；招募本科生加入研究团队，并与研究生导师配对；编写关于可持续碳捕集研究的外联材料；让STEM领域未被充分代表的少数族裔和CCS前沿研究领域的女性参与进来。该项目的前提是，CCS吸附分离工艺的改变性改进将需要同时开发新材料和利用这些新材料的专门设计工艺。本研究的主要目的是研究和开发一种新的系统框架，将金属有机框架（MOF）吸附材料的设计与碳捕获的吸附过程设计以可持续的方式结合起来。该项目的基础研究将设计、合成和表征新的MOF材料，包括新型沸沸体咪唑盐框架（ZIFs），它对二氧化碳的选择性高于氮和水蒸气，同时具有适当的高二氧化碳绝对容量。克服竞争性吸附对水的影响将是一个主要的焦点。利用最先进的过程级建模，项目团队将围绕新型吸附剂优化吸附过程，并探索基于mof的吸附过程的实际效率极限，以满足所需的CCS技术和经济标准。吸附过程已用于大规模应用，如空气分离，具有高可靠性。发现新的、有效的二氧化碳捕获吸附剂和新的、最佳的吸附剂工艺配置将是CCS的一个阶段性发展。

Proposal Number: 1604890, PI: Hupp, J.Title: SusChEM: Integrated Materials and Process Systems Development for Sustainable Carbon CaptureA vision receiving serious attention for slowing the increase of CO2 emissions in the atmosphere is to capture the CO2 at large point generation sources especially electric power plants and store it in stable geological formations. Before CO2 can be sequestered, it must be separated from the other species in the power plant's flue gas which contains primarily nitrogen and water vapor, with other trace gases. Economical carbon capture and sequestration (CCS) from power plant flue gas could thus be part of the mid-term solutions to mitigate climate change while renewable energy technologies continue to be installed in the nation's power grids. This project will develop new porous materials capable of removing CO2 from flue gas, as well as process-level technology using these materials, with the long-term goal of lowering the cost and energy requirements for carbon capture. The research will also be effectively integrated into education and outreach activities, including training of graduate students in a highly interdisciplinary environment to help them to develop a broad outlook and to develop good teamwork and communication skills; recruiting of undergraduate students to the research team and pairing them with graduate student mentors; developing outreach material on the research about sustainable carbon capture; and involving underrepresented minorities in STEM and women in the forefront research area of CCS.The premise of this project is that game-changing improvements of adsorption separation processes for CCS will require simultaneous development of new materials and specially designed processes that take advantage of these new materials. The primary objective of the research is to investigate and to develop a novel and systematic framework of integrating the design of metal-organic framework (MOF) sorbent materials and the design of adsorption processes for carbon capture in a sustainable way. The project's fundamental research will design, synthesize, and characterize new MOF materials including novel zeolitic imidazolate frameworks (ZIFs) with high selectivity for CO2 over nitrogen and water vapor, together with suitably high absolute capacity for CO2. Overcoming the effects from competitive adsorption of water will be a primary focus. Using state-of-the-art process-level modeling, the project team will optimize adsorption processes around the new class of sorbents and explore the real efficiency limits of MOF-based adsorption processes that meet desired CCS technical and economic criteria. Adsorption processes are already used in large-scale applications, such as air separation, with high reliability. Discovery of new and efficient adsorbents for CO2 capture and new, optimal process configurations for these sorbents would be a step-out development in CCS.
