SBIR Phase I: Novel Polymeric Membranes Based on Room-Temperature Ionic Liquids for Carbon Dioxide Removal from Shifted Syngas

这项小型企业创新研究（SBIR）第一阶段项目提出开发基于室温离子液体（RTILs）的新型二氧化碳选择性聚合物膜，以提高先进IGCC发电厂二氧化碳捕集的成本和效率。该项目的成功将使使用环保和经济可行的膜工艺从IGCC发电厂转移的合成气中去除二氧化碳成为可能，同时满足美国能源部（DOE）的目标，即至少捕获90%的二氧化碳，而电费的平均成本增加不到10%。RTIL性能的独特组合（出色的CO2/H2分离性能，以及定制结构-性能关系的能力）使RTIL成为下一代CO2/H2分离膜的有希望的候选材料。这项研究的更广泛/商业影响将是提高对RTIL基聚合物材料的理解。保利(RTILs) ?以及它们在气体分离中的应用潜力。将poly（RTILs）用于拟议的应用是前所未有的，从未报道过。如果RTILs可以制成稳定的固体膜，那么第一阶段的研究结果将有助于推进用于CO2/H2分离的膜技术，并使人们进一步了解使用poly（RTILs）作为膜材料的能力。超薄多聚膜（RTILs）的成功开发将为制造和使用这些基于RTILs的膜材料带来新的方法，不仅适用于合成气和IGCC应用，也适用于其他与二氧化碳相关的气体分离。

This Small Business Innovation Research (SBIR) Phase I project proposes to develop novel CO2-selective polymeric membranes based on room-temperature ionic liquids (RTILs) for improving the cost and efficiency of CO2 capture from advanced IGCC power plants. The success of this project will enable the use of an environmentally benign and economically viable membrane process to remove CO2 from shifted syngas in IGCC power plants and at the same time meet the Department of Energy (DOE) target of at least 90% capture of CO2 with less than 10% increase in the levelized cost of electricity. The unique combination of RTIL capabilities (excellent CO2/H2 separation properties, along with the capability to tailor structure-property relationships) makes RTILs a promising candidate material for the next generation of membranes for CO2/H2 separations.The broader/commercial impact of this research will be to improve the understanding of RTIL- based polymeric materials ? poly(RTILs) ? and their potential for use in gas separations. Using poly(RTILs) for the proposed application is unprecedented and has never been reported. If RTILs can be made into a stable solid membrane, the results of this Phase I work will aid in the advancement of membrane technologies used in CO2/H2 separations, and enable a further understanding of the capability of using poly(RTILs) as membrane materials. The successful development of membranes with ultra-thin poly(RTILs) layers will lead to new methods for fabricating and using these RTIL-based membrane materials not only for syngas and IGCC applications, but for other CO2-related gas separations as well.
