摘要CTS-9714629 J.Schwank这是由动力学和催化以及过程和反应工程项目共同资助的探索性研究的一小笔赠款。在这项研究中，Schwank教授和Kravaris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。精确控制薄膜温度的能力，独立于气相温度，将允许分开操作多相和均相反应。拟研究的模型反应是乙烯和丙烯在银膜上的选择性氧化。通过保持冷的气相和热的表面，部分氧化产物的选择性将被优化。还将探索具有独立表面组成和温度控制的微反应器阵列，作为实现空间不均匀但控制良好的温度分布的一种手段。本课程将探讨奈米温控流动反应器的控制理论，目标是在暂态操作条件下最大化转化率和选择性。

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.
