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

提案编号：1604890，PI：Hupp，J.标题：SusChEM：用于可持续碳捕获的集成材料和工艺系统开发对于减缓大气中CO2排放量的增加而受到严重关注的一种设想是在大型点产生源特别是发电厂捕获CO2并将其储存在稳定的地质构造中。在CO2可以被隔离之前，它必须与发电厂的烟道气中的其他物质分离，烟道气主要包含氮气和水蒸气以及其他痕量气体。因此，在可再生能源技术继续安装在国家电网中的同时，从发电厂烟气中经济地捕获和封存碳可能是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，长期目标是降低碳捕获的成本和能源需求。研究还将有效地纳入教育和外联活动，包括在高度跨学科的环境中培训研究生，帮助他们开拓广阔的视野，培养良好的团队合作和沟通技能;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获研究的外联材料;该项目的前提是，CCS吸附分离工艺的改变游戏规则的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的工艺。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）吸附剂材料的设计和吸附过程的设计以可持续的方式整合起来。该项目的基础研究将设计、合成和表征新的MOF材料，包括新型沸石咪唑酯骨架（ZIF），该材料对二氧化碳（相对于氮气和水蒸气）具有高选择性，并且对二氧化碳具有适当高的绝对容量。克服水的竞争性吸附的影响将是一个主要的焦点。利用最先进的工艺级建模，项目团队将围绕新的吸附剂类别优化吸附工艺，并探索符合CCS技术和经济标准的基于MOF的吸附工艺的真实的效率极限。吸附过程已经在大规模应用中使用，如空气分离，具有高可靠性。发现新的和有效的二氧化碳捕集吸附剂和新的，这些吸附剂的最佳工艺配置将是CCS的一个跨出的发展。

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.
