Continuous flow reactors are almost always operated at steady state. We will consider three types the continuous stirred tank reactor (CSTR). the plug flow reactor (PFR). and the packed bed reactor (PBR). Detailed descriptions of these reactors can be found in both the Professional Reference Shelf (PRS) for Chapter 1 and in the Visual Encyclopedia of Equipinent on the CD-ROM,... 

In nonlinear regression analysis, we search for those parameter t alues that minimize the sum of the squares of the differences beiw een the measured values and the calculated values for all the data points.- Not only can nonlinear regression find the best estimates of parameter values, it can al,so be used to discriminate between different rate law models, such as the Langmutr-Hin-shelw ood models discussed in Chapter 10. Many software programs are available to find these parameter values so that all one has to do is enter the data, The Polymath software will be used to illustrate this technique. In order to carry out the search efficiently, in some cases one has to enter initial estimates of the parameter -alues close to the actual values. These estimates can be obtained using Ihe linear-least-squares technique discussed on the CD-ROM Professional Reference Shelf. 

Each type of reactor is examined with respect to these criteria and given a rating of good (G), fair fFl, or poor fP). What follows is a brief description of each of the laboratory reactors. The reason.s for rating each reactor for each of the criteria are given in Professional Reference Shelf R5.4 on the CD-ROM. 

Pharmacokinetic models for drug delivery are given in Professional Refere Shelf R7.5. 

We simp ) combine Equation (8-72) and the equation for TV and then substitute the result into Equation (8-73) and plot 5 as a function of To- From Figure 8-25, we see that for a given value of 1C i(1+k)], if we were to increase the entering temperature from some low-value Toj (7, ) to a higher entering temperature value 02 (F i). we would reach a point at which runaway would occur. Further discussions are given on the CD-ROM professional reference shelf R8.2. Referring to Equation (8-70). we can infer...

The Kunii-Levenspiel model for fluidization is given on the CD-ROM along with a comprehensive example problem. The rale limiting transpon steps are also discussed. See Professional Reference Shelf R12.3. 

This book and interactive CD-ROM is intended for use as both an undergraduate-level and a graduate-level text in chemical reaction engineering. The level will depend on the choice of chapters and CD-ROM Professional Reference Shelf (PRS) materia to be covered and the type and degree of difficulty of problems assigned. 

The interactive CD-ROM is a novel and unique part of this book. The main purposes of the CD-ROM are to serve as an enrichment resource and as a professional reference shelf. The home page for the CD-ROM and the CRE web site (w ivw.engin.umich.edu/ cre/fagler gurmen) is shown in Figure P-3. 

Be sure to view the actual photographs of industrial reactors on the DVD-ROM and on the Web site. There are also links to view reactors on different Web sites. The DVD-ROM also includes a portion of the Visual Encyclopedia of Equipment— Chemical Reactors developed by Dr. Susan Montgomery and her students at the University of Michigan. Also see Professional Reference Shelf on the DVD-ROM for Reactors for Liquid Phase and Gas Phase Reactions. ... 

The space limes for a number of industrial reactions are given on the Professional Reference Shelf R2.2 on the DVD-ROM/Web. 

The reaction is first order in oxygen free radical and first order in methanol therefore, we say that both the reaction and the rate law are elementary. This form of the rate law can be derived from Collision Theory, as shown in the Professional Reference Shelf 3A on the DVD-ROM. There are many reactions where the stoichiometric coefficients in the reaction are identical to the reaction orders, but (he reactions are not elementary, owing to such things as pathways involving active intermediates and series reactions. For these reactions that are not elementary but whose stoichiometric coefficients are identical to the reaction orders in the rate law. we say the reaction follows an elementary rare law. For example, the oxidation reaction of nitric oxide discussed earlier,... 

Example 3-1. Make a plot of k versus T and In k versus (l/T) for E = 200 kJ/mol and for = 50 kj/mol. (1) Write a couple of sentences describing what you find. (2) Next write a paragraph describing the activation. how it affects chemical reaction rates, and what its origins are. Collision Theory—Professional Reference Shelf. Make an outline of the steps (hat were used to derive... 

Equilibrinm Conversioii. For reveisible reactions carried out in a seinibatch reactor, the maximum attainable conversion (i.e., the equilibrium conversion) will change as the reaction proceeds because more reactant is continuously added to the reactor. This addition shifts the equilibrium continually to the right toward more product. Further discussion on this point and calculation of the equilibrium conversion can be found on the Professional Reference Shelf R6.1D on the DVD-ROM and on the Web. 

For stock preparations, storage conditions and shelf life have to be justified on the basis of, for example, analytical data or professional judgement, which may be based on literature references.
