Example 6.5 Find the optimal temperature profile, T z), that maximizes the concentration of component B in the competitive reaction sequence of Equation (6.1) for a piston flow reactor subject to the constraint that F=3h. 

We regard the essential aspects of chemical reaction engineering to include multiple reactions, energy management, and catalytic processes so we regard the first seven chapters as the core material in a course. Then the final five chapters consider topics such as environmental, polymer, sohds, biological, and combustion reactions and reactors, subjects that may be considered optional in an introductory course. We recommend that an instmctor attempt to complete the first seven chapters within perhaps 3/4 of a term to allow time to select from these topics and chapters. The final chapter on multiphase reactors is of course very important, but our intent is only to introduce some of the ideas that are important in its design. 

High-pressure models applicable to pressure vessels and chemical reactors subjected to more than 15 psig... 

An individual reactor in a train can, of course, run away because of its own internal disturbances, but it can also send disturbances ahead to affect the stability of downstream reactors. If there is no intermediate heat exchange, the train acts like a single adiabatic reactor, subject only to disturbances in its feed. Within the stages there is backmixing, but there is none otherwise. A reactor series can also serve as a model for packed-bed reactors, if the upstream propagation implied by Equation (12) is not realistic.

Equations (4-147) and (4-148) describe the conversion and coke profiles in an isothermal reactor subject to deactivation by coke formation via a parallel mechanism. Derive the corresponding equations for deactivation via a series mechanism. 

The aforementioned researchers have utilized experimental and computer simulation studies of this reaction to assess the performance of adiabatic reactors subjected to various modes of operation. An analysis of the performance of a plug flow reactor operated adiabaticaUy with a feed entering at 20°C that is 0.4 M in thiosulfate and 0.6 M in hydrogen peroxide indicates that the space time necessary to achieve 70% conversion of the limiting reagent is 38.9 s. 

One danger in a brief review article is that the examples given may be so slight in content that significant aspects of the theory may not be adequately illustrated. We have chosen, therefore, to confine the examples to a single model or problem, namely, the shutdown of a nuclear reactor subject to xenon poisoning, in order to save having to develop the details of the...
