This SBIR Phase I project will show proof-of-concept for a structured bed reactor using dry materials coating metal foil surfaces to capture CO2 from power plants and other combustion sources. This process will employ a scale-up version of an existing heat exchanging reactor platform in combination with sorbent materials developed by Hoffman at the National Energy Technology Laboratory and other new materials, that can lower the regenerative heat by 30-40% compared to the use of CO2 capture with aqueous methanolamine currently in use. The system could remove 90% of the CO2 while keeping the increase in cost of electricity under the 35% threshold.The broader/commercial impact of the project will be to have effective mechanisms to remove CO2 at low costs. When commercialized, the technology will reduce green house gas emissions and reduce imports of energy from foreign sources. This is expected to be done below the U.S. Department of Energy aggressive targets of $20 per ton of CO2 removal and 35% increase incost of electricity. Further, this technology will impose very low parasitic backpressure on power plant exhaust. The transformational nature of the technology, coupled with the involvement of graduate and undergraduate students, will ensure that the United States maintains a technological lead in developing and deploying advanced energy technologies. The technology could also be applied to other sources of CO2 and it could be eventually be exported to countries like China and India.

该SBIR第一阶段项目将展示结构化床反应器的概念验证，该反应器使用涂覆金属箔表面的干燥材料来捕获发电厂和其他燃烧源中的二氧化碳。 该工艺将采用现有热交换反应器平台的放大版本，结合由国家能源技术实验室的霍夫曼开发的吸附剂材料和其他新材料，与目前使用的用含水甲醇胺捕获CO2相比，其可以将再生热降低30-40%。该系统可以去除90%的CO2，同时将电力成本的增加控制在35%的阈值以下。该项目的更广泛/商业影响将是以低成本去除CO2的有效机制。 一旦商业化，该技术将减少绿色家庭气体排放，并减少从国外进口能源。这预计将低于美国能源部的积极目标，即每吨二氧化碳排放20美元，电力成本增加35%。此外，该技术将对发电厂排气施加非常低的寄生背压。这项技术的变革性质，加上研究生和本科生的参与，将确保美国在开发和部署先进能源技术方面保持技术领先地位。 该技术还可以应用于其他二氧化碳来源，并最终出口到中国和印度等国家。
