ABSTRACT CTS-9714629 J. Schwank This is a Small Grant for Exploratory Research co-funded by the Kinetics and Catalysis and the Process and Reaction Engineering programs. In this research, Professors Schwank and Kravaris will explore scientific applications of micromachined hot-plate chemical reactors containing catalytically active thin films. The ability to accurately control the film temperature, independently from the gas phase temperature, will allow the separate manipulation of heterogeneous and homogeneous reactions. The model reaction to be studied is the selective oxidation of ethylene and propylene on silver films. By maintaining a cold gas phase and a hot surface, the selectivity towards partial oxidation products will be optimized. Arrays of microreactors with independent surface composition and temperature control will be also explored as a means to achieve spatially nonuniform but well controlled temperature distributions. The control theory of nanoscale temperature-controlled flow reactor will be explored, with the objective of maximizing conversion and selectivity in a transient operating regime.

摘要 CTS-9714629 J. Schwank 这是一项用于探索性研究的小额赠款，由动力学和催化以及过程和反应工程项目共同资助。 在这项研究中，施万克和克拉瓦里斯教授将探索含有催化活性薄膜的微机械热板化学反应器的科学应用。 独立于气相温度精确控制薄膜温度的能力将允许单独操纵非均相和均相反应。 要研究的模型反应是乙烯和丙烯在银膜上的选择性氧化。 通过维持冷气相和热表面，将优化部分氧化产物的选择性。 还将探索具有独立表面成分和温度控制的微反应器阵列，作为实现空间不均匀但良好控制的温度分布的手段。 将探索纳米级温控流反应器的控制理论，目标是在瞬态操作状态下最大化转化率和选择性。
