PI：Alexandre F. Yokochi研究所：俄勒冈州州立大学提案编号：0748280职位：职业：在微结构反应器中实施可持续能源相关过程这是一项CAREER赠款，用于资助旨在开发可持续制氢的微反应器系统的研究和教育活动。微结构反应器与传统的宏观反应器相比具有几个优势，包括简单，可预测的流动路径和颗粒停留时间，短的扩散长度确保有效的传质过程、快速和有效的传热等，这通常使得能够简单地实施否则难以实施的过程。 该项目的一个目标是研究微反应器，其中同时存在液相反应和气体和液体系统之间的传质。 PI计划研究一个与能源相关的模型系统，用于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生反应的反应器的开发将产生一种不需要过量水或碘的系统，但仍能生产单独的含碘和硫的物流。本职业发展计划将探索反应式两阶段和三阶段流程的开发和实施，同时激发对微结构反应堆和能源相关问题的最新技术的教育理解。 该项目将以下列方式进行：1。探索微反应器中反应系统的低成本实现：这将探索微反应器可以以具有成本效益的方式为学术和工业研究生产的方式。特别地，将探索非常低成本的基于喷墨的接触光刻和玻璃的湿法蚀刻的应用以产生期望的系统，以及将有效的方式在反应器内部署催化材料。目前在PI？的实验室已经展示了这种低成本微反应器构建方法的初始步骤。这种低成本、低基础设施方法的发展将使其他人能够为他们的研究项目开发自己的系统。在离子液体中实现本生反应：在这里，将构建配备有合适控制和仪器的微结构降液膜和鼓泡塔反应器。目前的工作表明，本生反应可以在室温下在离子液体中发生，在间歇反应器中单独产生含碘和含硫的流。然而，热化学参数的确定是必不可少的系统识别和建模。使用这些反应器，溶解度，传质和反应动力学参数和不同的化学条件的影响进行本生反应在离子液体中将进行调查。教育融合：PI将通过以下方式加强OSU各级化学工程学生的教育经验：1）在高级顶点经验中引入讨论微结构反应器问题的模块，2）通过主办高级项目团队继续指导本科研究人员，约翰逊学者（大学新生）和SESEY（高中）的学生在实验室工作的问题在微反应器和能源生产的过程实施的接口。这些学生将成为有关工作的研究团队的一个组成部分。更广泛的影响：这项研究将导致一种新的方法进行本生反应与硫碘热化学循环的发展。所提出的流体处理方法与当前的工艺完全兼容，并且应该大大改进它，因此将是可持续制氢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，并使各种未来的进步导致这种方法的实际实施。同时，这项工作将被用作一个平台，以暴露大学预科，本科和研究生（和同事教师！）涉及在微结构反应器中实施过程和室温离子液体的不寻常性质的问题。

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.
