Modeling Transient Tracing in Plug-Flow Reactors: A Case Study. Eric Walter, Luc Pronzato, Yee Soong, Masood Otarod, and John Happel* Page 485. Figure 2 as printed is not correct. The correct figure follows. Note that Figure 2 in this article corresponds t o Figure 1 in Soong et al. (19861, except that we do not report time of flight (TOF)because Soong et al. computed TOF by assuming a pool model for the plug-flow data. We have chosen only those points corresponding to time on stream 0.5, 16,40,64, and 313 h. Also, by use of eq 14 the overall reaction velocity V corresponding to total conversion designated by the asterisks (*) in Figure 5 is readily computed. 5
