PI：Alexandre F.Yokochi研究所：俄勒冈州立大学提案编号：0748280标题：Career：在微结构反应堆中实施与可持续能源相关的过程这是一项职业资助，用于资助旨在开发用于可持续氢气生产的微反应器系统的研究和教育活动。与传统的宏观反应器相比，微结构反应器具有几个优势，包括简单、可预测的流动路径和颗粒停留时间、较短的扩散长度、确保高效的传质过程、快速和高效的热传递等，这些优点通常使原本难以实现的过程能够简单实施。这个项目的一个目标是研究微反应器，在这些反应器中，液体中的反应和气液系统之间的传质是同步进行的。PI计划研究一个与能源相关的模型系统，即可持续制氢的硫-碘热化学水分解方法。具体地说，在室温离子液体中进行本森反应的反应堆的开发将产生一个不需要过量水或碘的系统，但仍然可以生产单独的碘和硫蒸气。智力优势：这个职业发展计划将探索反应性两阶段和三阶段工艺的开发和实施，同时启发人们对微结构反应堆和能源相关问题的最新技术的理解。将以下列方式实施该项目：1.探索在微型反应堆中低成本地实施反应系统：这将探索以具有成本效益的方式生产微型反应堆的方式，供学术和工业研究使用。特别是，将探索以极低成本的喷墨为基础的接触光刻和玻璃的湿法蚀刻以生产所需系统的应用，以及在反应器内部署催化材料的有效方式。目前在皮？S实验室的工作已经证明了这种低成本微反应器建造方法的初步步骤。开发这种低成本、低基础设施的方法将使其他国家能够为其研究目的开发自己的系统。在离子液体中实现本森反应：在这里，将建造配备适当控制和仪器的微结构降膜和鼓泡塔反应器。目前的工作表明，本森反应可以在室温下在离子液体中发生，同时在间歇反应器中分离产生含碘和硫的蒸气。然而，热化学参数的确定是系统辨识和建模的关键。利用这些反应器，将研究在离子液体中进行本森反应时的溶解度、传质和反应动力学参数以及不同的化学条件对反应的影响。教育整合：PI将通过以下方式加强俄亥俄州立大学各级化学工程专业学生的教育经验：1)在高级顶峰经验中引入讨论微结构反应堆问题的模块；2)通过在实验室接待高级项目团队、Johnson学者(大学新生)和SESEY(高中生)学生，继续指导本科生研究微反应器过程实施和能源生产方面的问题。这些学生将成为有关工作研究团队中不可或缺的一部分。更广泛的影响：这项研究将导致开发一种执行与硫-碘热化学循环相关的本森反应的新方法。所提出的流体处理方法与目前的工艺完全兼容，应该会大大改进它，因此将是可持续氢气生产领域的真正变革性研究，为参与可再生能源的个人开辟了一个新的研究领域，并使各种未来的进展能够导致该方法的实际实施。同时，这部作品将被用作一个平台，展示大学预科、本科生和研究生(以及其他教职员工！)关于在微结构反应堆中实施工艺的问题，以及室温离子液体的特殊性质。

PI: Alexandre F. Yokochi Institution: Oregon State University Proposal Number: 0748280Title: CAREER: Implementation of Sustainable Energy Related Processes in Microstructured ReactorsThis is a CAREER grant to fund research and educational activities aimed at developing microreactor systems for sustainable hydrogen production.Microstructured reactors offer several advantages over conventional macroscopic reactors including simple, predictable flow paths and particle residence times, short diffusion lengths ensuring efficient mass transfer processes, fast and efficient heat transfer and others, which frequently enable simple implementation of processes that are otherwise difficult. A goal of this project is to look at microreactors where simultaneously there is reaction in the liquid phase and mass transfer between gas and liquid systems. The PI plans to examine an energy related model system, the Sulfur-Iodine Thermochemical Water Decomposition method for sustainable hydrogen production. Specifically the development of a reactor in which the Bunsen reaction is carried out in a room temperature ionic liquid will result in a system that does not require excess water or iodine, and yet still achieves the production of separate iodine and sulfur bearing streams.Intellectual Merit: This CAREER development plan will explore the development and implementation of reactive two and three phase processes, while inspiring educational understanding of the state-of-the-art of microstructured reactors and energy related issues. The project will be approached in the following manner:1. Exploration of the low cost implementation of reactive systems in microreactors: This will explore the manner in which microreactors can be produced in a cost efficient manner for academic and industrial research. In particular, the application of very low cost inkjet based contact lithography and wet etching of glass to produce the desired systems will be explored, as will efficient manners to deploy catalytic materials within the reactors. Current work in the PI?s laboratory has demonstrated the initial steps in this low cost microreactor construction methodology. The development of this low cost, low infrastructure methodology will enable others to develop their own systems for their research purposes.2. Implementation of the Bunsen Reaction in an Ionic Liquid: Here, microstructured falling liquid film and bubble column reactors equipped with suitable controls and instrumentation will be constructed. Current work has shown that the Bunsen reaction can be caused to occur at room temperature in an ionic liquid with separate production of iodine and sulfur bearing streams in a batch reactor. However, determination of thermochemical parameters is essential for system identification and modeling. Using these reactors, solubility, mass transfer and reaction kinetic parameters and the effect of varying chemical conditions associated with performing the Bunsen reaction in an ionic liquid will be investigated.3. Educational Integration: The PI will strengthen the educational experience for Chemical Engineering students of all levels at OSU through 1) the introduction of modules discussing microstructured reactor issues in the senior capstone experience and 2) continuing to mentor undergraduate researchers through hosting senior project teams, Johnson scholars (college freshmen) and SESEY (high school) students in the laboratory to work on issues at the interface of process implementation in microreactors and energy production. These students will become an integral part of the research team on the work in question. Broader Impact: This research will result in the development of a novel method for performing the Bunsen reaction associated with the Sulfur-Iodine thermochemical cycle. The fluid processing methods proposed are fully compatible with the current process, and should greatly improve it, and would therefore be truly transformational research in the field of sustainable hydrogen production, opening a new area of research for individuals involved with renewable energy and enabling various future advances leading to the practical implementation of this method. Simultaneously, the work will be used as a platform to expose pre-college, undergraduate and graduate students (and fellow faculty!) to the issues surrounding the implementation of processes in microstructured reactors and the unusual properties of room temperature ionic liquids.
