Elastic Layered Metal-Organic Frameworks for Carbon Capture

该项目研究了使用新型固体吸附剂从烟道气流中捕获CO2的可行性。该研究是分子模拟和实验的结合，以研究CO2和弹性层状金属有机框架（ELMs）之间的相互作用。该项目还包括一个假设的500兆瓦发电厂改造的ELM吸附系统的LCA。 假设是这样的吸收剂在吸收和释放CO2方面将是高效的，而没有实质性的能量损失。 该项目正面解决了在含有H2O和其他杂质（如SO2、NOx等）的杂乱烟气流中捕获CO2的挑战。暴露于潮湿气流的重复循环可能最终使这些吸附剂降解。这一过程的分子模拟将提供这种技术可行程度的指示。 如果成功，这些进展将有可能在指导有效的CO2固体吸附剂结构的设计和碳捕获的经济性方面具有变革性。研究结果将被纳入远程教育课程教授给工业观众和推广到初中和高中学生在安阿伯。 本科生将参与研究。 与日本研究人员的合作是该项目的一个重要组成部分。汉密尔顿7/22/10

This project examines the feasibility of using new solid sorbents for CO2 capture from flue gas streams. The research is a combination of molecular modeling and experimentation to study the interactions between CO2 and Elastic Layered Metal-Organic Frameworks (ELMs). The project also includes an LCA for a hypothetical 500 MW power plant retrofitted with an ELM adsorption system. The hypothesis is that such absorbents would be highly efficient in adsorbing and releasing CO2 without substantial energy penalties. The project addresses head-on the challenge of CO2 capture in the context of messy flue gas streams, which contain H2O and other impurities such as SO2, NOx, etc. Repeated cycling of exposure to a moist gas stream may ultimately degrade these sorbents. Molecular modeling of this process will provide an indication of the extent to which this technology is feasible. If successful, the advances would have the potential to be transformative in guiding the design of effective CO2 solid sorbent structures and economics of carbon capture. Research findings will be integrated into distance education classes taught to industrial audiences and outreach to middle and high school students in Ann Arbor. Undergraduates will participate in the research. A collaboration with researchers in Japan is an important component of the project.This project is co-funded by OISE-Japan.Bruce K. Hamilton7/22/10
