Through a research planning visit, Dr. Kevin Whitty of the University of Utah will initiate a collaborative project with Swedish partners, Drs. Anders Lyngfelt, Tobias Martison, and Henrik Leion, at the Chalmers University in Gothenburg. Together, they intend to pursue questions related to chemical looping combustion by drawing on the renowned expertise in chemical looping at Chalmers and the well established strengths in chemical kinetics at the University of Utah. The Swedish partners offer bench-scale pilot facilities for chemical looping combustion with interconnected fluidized beds that can be used to oxidize a variety of gaseous fuels and coals. This is complemented by the Utah group's progress in developing kinetic parameters needed to model the combustion of coal and petroleum coke with an oxygen carrier. The initial collaboration is expected to help the U.S.-Swedish team extend their research with the goal of accelerating progress in the field of chemical looping with oxygen uncoupling (CLOU) . If successful, results may contribute to the fundamental engineering required to understand and develop a CLOU process that effectively reduces the residence time for solids in fuel reactors by a significant percent. Likely broader impacts include advances in knowledge of theoretical and practical CO2 capture. Envisioned long-term applications could lead to designs for continuous reactors to demonstrate CLOU at larger scales and at reduced costs. To build on preliminary findings, the principal investigator plans to submit a follow-on application to the National Science Foundation for cooperative research on related transport and thermal fluids phenomena. Furthermore, one U.S. graduate student from the University of Utah will travel with Dr. Whitty to Gothenburg and participate in joint activities at Chalmers, thereby gaining beneficial international research experience. This early career access to expert Swedish engineers and specialized reactor scaling should lead to a beneficial professional network in the increasingly important fields related to energy and combustion.

通过一次研究计划访问，犹他大学的凯文·惠蒂博士将与瑞典合作伙伴凯文·惠蒂博士发起一个合作项目。安德斯·林菲特、托拜厄斯·马蒂森和亨里克·利昂，来自哥德堡查尔姆斯大学。他们打算利用查尔默斯大学在化学环方面的著名专业知识和犹他大学在化学动力学方面的优势，共同研究与化学环燃烧有关的问题。瑞典合作伙伴为化学循环燃烧提供了实验规模的试验设施，这些设施具有相互连接的流化床，可用于氧化各种气体燃料和煤。犹他小组在开发动力学参数方面取得了进展，需要用氧载体模拟煤和石油焦的燃烧。最初的合作有望帮助美国-瑞典团队扩展他们的研究，目标是加速氧解偶联化学环（CLOU）领域的进展。如果成功，研究结果可能有助于理解和开发CLOU过程所需的基础工程，该过程可以有效地减少固体在燃料反应堆中的停留时间。可能产生的更广泛影响包括二氧化碳捕获理论和实践知识的进步。设想的长期应用可能导致连续反应堆的设计，以更大的规模和更低的成本展示CLOU。在初步发现的基础上，首席研究员计划向美国国家科学基金会提交后续申请，合作研究相关的输运和热流体现象。此外，一名来自犹他大学的美国研究生将与Whitty博士一起前往哥德堡，并参加Chalmers的联合活动，从而获得有益的国际研究经验。这种早期职业接触到瑞典工程师专家和专门的反应堆规模，应该会在与能源和燃烧相关的日益重要的领域形成一个有益的专业网络。
