  • Computational Chemical Reaction Engineering

    As a prologue to the future, our profession is evolving to one of molecular chemical engineering. For chemical reaction engineers, computational chemistry and molecular modeling could well be our future. Thermodynamic properties of molecular species that are used in reactor design problems can be readily estimated from thermodynamic data tabulated in standard reference sources such…

A.2 Equal-Area Graphical Differentiation There are many ways of differentiating numerical and graphical data (cf. Chapter 7). We shall confine our discussions to the technique of equal-area differentiation. In the procedure delineated here,…

  • Industrial Reactors

    Be sure to view the actual photographs of industrial reactors on the CRE Web site so you will know them when you run into them. There are also links to view reactors on different Web sites. The CRE Web site also includes a portion of the Visual Encyclopedia of Equipment, encyclopedia.che.engin.umich.edu, “Chemical Reactors” developed by Dr. Susan…

  • Mole Balances

    The first step to knowledge is to know that we are ignorant. —Socrates (470–399 B.C.) The Wide, Wild World of Chemical Reaction Engineering Chemical kinetics is the study of chemical reaction rates and reaction mechanisms. The study of chemical reaction engineering (CRE) combines the study of chemical kinetics with the reactors in which the reactions occur.…

  • The General Mole Balance Equation (GMBE)

    To perform a mole balance on any system, the system boundaries must first be specified. The volume enclosed by these boundaries is referred to as the system volume. We shall perform a mole balance on species j in a system volume, where species j represents the particular chemical species of interest, such as water or NaOH (Figure 1-3). A mole balance…

  • The Rate of Reaction, –rA

    Identify – Kind – Number – Configuration The rate of reaction tells us how fast the number of moles of one chemical species are being consumed to form another chemical species. The term chemical species refers to any chemical component or element with a given identity. The identity of a chemical species is determined by the kind, number, and configuration of that species’ atoms.…

  • Introduction

    The man who has ceased to learn ought not to be allowedto wander around loose in these dangerous days. —M. M. Coady A. Who Is the Intended Audience? This book was written with today’s students in mind. It provides instantaneous access to information; does not waste time on extraneous details; cuts right to the point;…
