I learned about chemical reactors at the knees of Rutherford Aris and Neal Amundson, when, as a surface chemist, I taught recitation sections and then lectures in the Reaction Engineering undergraduate course at Minnesota. The text was Aris Elementary Chemical Reaction Analysis, a book that was obviously elegant but at first did not seem at all elementary. It described porous pellet diffusion effects in chemical reactors and the intricacies of nonisothermal reactors in a very logical way, but to many students it seemed to be an exercise in applied mathematics with dimensionless variables rather than a description of chemical reactors.

Up to now we have focused on the steady-state operation of nonisothermal reactors. In this section the unsteady-state energy balance wtU be developed and then applied to CSTRs, plug-flow reactors, and well-mixed batch and semibateh reactors.

A reminder neither of the two heat-transport models considered in this section account for thermal conduction in the bed. If gradients are substantial, this can be a miserable assumption as shown by the discussion of nonisothermal reactors in Chapter 7. It is probably fair to say that if any conduction effects are included, axial or radial, the problem formulation is not complicated very much (just the addition of a second derivative term with respect to temperature), but the solution to the problem becomes a numerical one and sufficiently complicated to be a subject...
