Purchase of a Catalytic Reactor for a Senior Laboratory Experiment

一个具有自动化学分析、数据记录和控制能力的实验室规模的连续催化反应器将由购买的部件组装而成，用于内布拉斯加州大学林肯大学化工系的本科实验室教学。学生将在三个不同的本科生班级设计实验方案和操作该设备：当前的高级单元操作实验室课程；二年级的方法和测量实验室；以及由积极进取的学生学习的高年级除法独立指导学习课程。对于单元实验室，将通过正丁烷在负载铂的沸石催化剂上的反应来讲授反应动力学基础以及催化剂活性、选择性和性能随温度和压力的变化。对于二年级的测量实验室，将教授实验设计、数据统计分析、扩散效应入门和量纲分析等较简单的实验，如停留时间分布的痕迹分析和作为温度和压力的函数的吸附等温线测定。独立研究取决于参与其中的学生和教授。增加一个连续动力学实验是正在进行的更新工作的一部分，其中包括本科生实验室中补充的批次和连续实验。

A bench-scale continuous catalytic reactor with automated chemical analysis, data logging and control capabilities will be assembled from purchased components for use in undergraduate laboratory instruction in the Department of Chemical Engineering at the University of Nebraska Lincoln. Students will design experimental protocols and operate this equipment in three different undergraduate classes: the current senior Unit Operations laboratory course; the sophomore Methods and Measurements laboratory; and the upper-class division independent directed study course taken by highly motivated students. For the Unit laboratory, reaction kinetics fundamentals and catalyst activity, selectivity and performance as a function of temperature and pressure will be taught by reactions such as n-butane over a platinum-loaded zeolite catalyst. For the sophomore measurements lab, experimental design, statistical analysis of data, introductory diffusional effects, and dimensional analysis will be taught with simpler experiments, such as trace analysis for residence time distribution and adsorption isotherm determination as functions of temperature and pressure. Independent studies depend on the students and professors involved. The addition of a continuous kinetics experiment is part of an ongoing updating effort which includes complementary sets of batch and continuous experiments in the undergraduate laboratory.
