This project is directed at two goals. First, an experiment involving catalytic isomerization of n-butenes is built and introduced into the two required senior chemical engineering laboratory courses. The experiment is based on an existing gas chromatograph and involves a relatively simple apparatus built around a tubular glass reactor packed with chromia alumina catalyst. Purchased equipment includes an FID detector and second inlet for the chromatograph, a capillary column capable of separating the three n-butene isomers, and a tube furnace. The students become familiar with the essentials of heterogeneous catalysis and see how kinetic and equilibrium data for catalytic reactions are generated and analyzed. Second, an existing experiment involving the dynamics and control of a multivessel flow system is interfaced to the Internet. This setup allows students (using Web software such as Netscape Navigator) in several nonlaboratory courses (including a first-year elective open to all engineering students) to see, run, and acquire data from this system. Equipment includes a color video camera, motorized lens, tilt and pan stage for the camera, video compression card, and Pentium computer. *

这个项目有两个目标。 首先，本研究设计了一个丁烯催化异构化的实验，并将其引入到化学工程实验的两门必修课程中。 该实验是基于现有的气相色谱仪，并涉及一个相对简单的装置周围的管状玻璃反应器填充氧化铬氧化铝催化剂。 购买的设备包括一个FID检测器和色谱仪的第二个入口，一个能够分离三种正丁烯异构体的毛细管柱和一个管式炉。 学生熟悉多相催化的基本原理，并了解如何生成和分析催化反应的动力学和平衡数据。 第二，现有的实验涉及多血管流动系统的动力学和控制接口到互联网。 这种设置允许学生（使用网络软件，如Netscape Navigator）在几个非实验室课程（包括一年级选修开放给所有工程专业的学生）看到，运行，并从这个系统中获取数据。 设备包括一台彩色摄像机、电动透镜、摄像机的俯仰和平移台、视频压缩卡和奔腾计算机。 *
