The project applies convergent environmental research to the mitigation of carbon dioxide (CO2) emissions associated with one of the world’s major commodity chemical processes – the steam cracking of ethane to produce ethylene (a building block molecule used widely in chemical manufacturing). Steam crackers are a major source of CO2 emissions (18.8 million metric tons/year in the U.S. in 2014), resulting in about 0.5% of all stationary-source CO2 emissions in the U.S. The project focuses on research that integrates capability for CO2 capture and conversion into existing steam cracker units, thereby dramatically reducing the carbon footprint of those units. Environmentally convergent research will be realized through an assembled team of academic and industry researchers bringing specialized expertise in four critical areas: 1) CO2 capture, 2) CO2 conversion to higher-value chemicals, 3) process systems engineering integration, and 4) environmental sustainability assessment. Beyond the technical aspects, the project will pave a direct path to technology implementation, as aided by the collaboration with industry partner BASF. Educational and outreach efforts, focused on enhancing convergent R&D practices in both industrial and academic settings, will promote a future workforce much better equipped to tackle the world’s most pressing scientific, engineering and sustainability challenges.The project integrates CO2 capture and conversion to methanol into an ethylene production unit, where the CO2 comes from the flue gas of the steam cracker furnace, and is reacted with H2 byproduct, utilizing waste heat from the cracker to run the CO2 capture and conversion process. Specially designed ionic liquids (ILs) will be employed for CO2 capture, with research emphasis on the fundamental chemistry needed to balance the capture, CO2 activation, and catalytic conversion steps in an economically viable low-temperature methanol synthesis process. To that end, fundamental developments at the molecular level will be converged with extensive process modeling, simulation, and design optimization. Rigorous life cycle assessment (LCA) will be conducted for representative ethylene and methanol co-production facilities, and compared to stand-alone process units, with and without integrated CO2 capture and conversion. Highlights of the educational and outreach activities include, 1) a seminar series revolving around research presentations on CO2 capture and conversion by the university team balanced by lectures on industrial opportunities for CO2 capture and conversion by BASF engineers, 2) graduate student internships, and 3) a CO2 capture and conversion module for high school students to be disseminated through the UTeachEngineering: “Engineer Your World” program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将收敛性环境研究应用于与世界主要商品化学过程之一相关的二氧化碳（CO2）排放的缓解 - 相同的蒸汽破裂以生产乙烯（化学生产中广泛使用的构件分子）。蒸汽饼干是二氧化碳排放的主要来源（2014年在美国，每年1,880万吨/年），在美国，大约0.5％的所有固定源二氧化碳排放量的0.5％，该项目着重于将二氧化碳捕获和转换为现有的蒸汽裂缝单位的能力集成到能力，从而大幅度降低了这些单位的碳纤维足迹，从而将其转化为现有的蒸汽裂缝。环境融合的研究将通过一个由学术和行业研究人员组成的团队来实现，该团队将在四个关键领域带来专业专业知识：1）CO2捕获，2）CO2转换为高价值化学品，3）流程系统工程整合，4）环境可持续性评估。除了技术方面，该项目还将在与行业合作伙伴巴斯夫的协作的帮助下，为技术实施的直接途径铺平道路。教育和宣传努力，专注于增强工业和学术环境中的融合研发实践，将促进未来的劳动力，可以更好地应对世界上最紧迫的科学，工程和可持续性挑战，该项目将CO2捕获和转换与甲基烯的生产相结合，并将CO2与甲基甲基化的速度与蒸汽造成的蒸汽造成的储备量相结合。二氧化碳捕获和转换过程。专门设计的离子液体（ILS）将用于二氧化碳捕获，并研究强调在经济上可行的低温甲基烯醇合成过程中平衡捕获，二氧化碳激活和催化转化步骤所需的基本化学。为此，分子水平的基本发展将通过广泛的过程建模，仿真和设计优化融合。严格的生命周期评估（LCA）将用于代表性的乙烯和甲基烯醇共生产设施，并与具有和不具有集成的二氧化碳捕获和转换的独立工艺单位进行比较。 Highlights of the educational and outreach activities include, 1) a seminal series revolving around research presentations on CO2 capture and conversion by the university team balanced by lectures on industrial opportunities for CO2 capture and conversion by BASF engineers, 2) graduate student internships, and 3) a CO2 capture and conversion module for high school students to be disseminated through the UTeachEngineering: “Engineer Your World” program.This award reflects NSF's statutory使命，并被认为是通过基金会的知识分子优点和更广泛影响的审查标准通过评估值得支持的。
