Chemical reaction engineering (reaction engineering or reactor engineering) is a specialty in chemical engineering or industrial chemistry dealing with chemical reactors. Frequently the term relates specifically to catalytic reaction systems where either a homogeneous or heterogeneous catalyst is present in the reactor. Sometimes a reactor per se is not present by itself, but rather is integrated into a process, for example in reactive separations vessels, retorts, certain fuel cells, and photocatalytic surfaces. The issue of solvent effects on reaction kinetics is also considered as an integral part.[1]
Chemical reaction engineering as a discipline started in the early 1950s under the impulse of researchers at the Shell Amsterdam research center and the university of Delft. The term chemical reaction engineering was apparently coined by J.C. Vlugter while preparing the 1st European Symposium on Chemical Reaction Engineering which was held in Amsterdam in 1957.
Chemical reaction engineering aims at studying and optimizing chemical reactions in order to define the best reactor design. Hence, the interactions of flow phenomena, mass transfer, heat transfer, and reaction kinetics are of prime importance in order to relate reactor performance to feed composition and operating conditions. Although originally applied to the petroleum and petrochemical industries, its general methodology combining reaction chemistry and chemical engineering concepts allows optimization of a variety of systems where modeling or engineering of reactions is needed. Chemical reaction engineering approaches are indeed tailored for the development of new processes and the improvement of existing technologies.
The most important series of symposia are the International Symposia on Chemical Reaction Engineering or ISCRE conferences.[2] These three-day conferences are held every two years, rotating among sites in North America, Europe, and the Asia-Pacific region, on a six-year cycle. These conferences bring together for three days distinguished international researchers in reaction engineering, prominent industrial practitioners, and new researchers and students of this multifaceted field. ISCRE symposia are a unique gathering place for reaction engineers where research gains are consolidated and new frontiers explored. The state of the art of various sub-disciplines of reaction engineering is reviewed in a timely manner, and new research initiatives are discussed.[3]
In 1996, the ISCRE Board of Directors established the Neal R. Amundson Award for Excellence in Chemical Reaction Engineering. This award recognizes a pioneer in the field of Chemical Reaction Engineering who has exerted a major influence on the theory or practice of the field, through originality, creativity, and novelty of concept or application. The award is made every three years at an ISCRE meeting, and consists of a Plaque and a check in the amount of $5000. The Amundson Award is generously supported by a grant from the ExxonMobil Corporation. Winners of the award include:
In 2016, the ISCRE, Inc. Board of Directors will bestow the first Rutherford Aris Young Investigator Award for Excellence in Chemical Reaction Engineering.[4] This award will recognize outstanding contributions in experimental and/or theoretical reaction engineering research of investigators in early stages of their career. The recipient must be less than 40 years of age at the end of the calendar year in which the award is presented. The Aris Award is generously supported by a grant from the UOP, L.L.C., a Honeywell Company. The award consists of a plaque, an honorarium of $3000, and up to $2000 in travel funds to present at an ISCRE/NASCRE conference and to present a lecture at UOP. This award complements ISCRE's other major honor, the Neal R. Amundson Award. Winners of the award include:
Review of principles underlying rates of transformation of matter and energy; effect of temperature and catalysis on chemical reactions. Introduction to the basic ideas underlying chemical reaction engineering. May be taken for graduate credit.
This book is an introduction to the quantitative treatment of chemical reaction engineering. The level of the presentation is what we consider appropriate for a one-semester course. The text provides a balanced approach to the understanding of: (1) both homogeneous and heterogeneous reacting systems and (2) both chemical reaction engineering and chemical reactor engineering. We have emulated the teachings of Prof. Michel Boudart in numerous sections of this text. For example, much of Chapters 1 and 4 are modeled after his superb text that is now out of print (Kinetics a/Chemical Processes), but they have been expanded and updated. Each chapter contains numerous worked problems and vignettes. We use the vignettes to provide the reader with discussions on real, commercial processes and/or uses of the molecules and/or analyses described in the text. Thus, the vignettes relate the material presented to what happens in the world around us so that the reader gains appreciation for how chemical reaction engineering and its principles affect everyday life. Many problems in this text require numerical solution. The reader should seek appropriate software for proper solution of these problems. Since this software is abundant and continually improving, the reader should be able to easily find the necessary software. This exercise is useful for students since they will need to do this upon leaving their academic institutions. Completion of the entire text will give the reader a good introduction to the fundamentals of chemical reaction engineering and provide a basis for extensions into other nontraditional uses of these analyses, for example, behavior of biological systems, processing of electronic materials, and prediction of global atmospheric phenomena. We believe that the emphasis on chemical reaction engineering as opposed to chemical reactor engineering is the appropriate context for training future chemical engineers who will confront issues in diverse sectors of employment. We gratefully acknowledge Prof. Michel Boudart who encouraged us to write this text and who has provided intellectual guidance to both of us. MED also thanks Martha Hepworth for her efforts in converting a pile of handwritten notes into a final product. In addition, Stacey Siporin, John Murphy, and Kyle Bishop are acknowledged for their excellent assistance in compiling the solutions manual. The cover artwork was provided courtesy of Professor Ahmed Zewail's group at Caltech, and we gratefully thank them for their contribution. We acknowledge with appreciation the people who reviewed our project, especially A. Brad Anton of Cornell University, who provided extensive comments on content and accuracy. Finally, we thank and apologize to the many students who suffered through the early drafts as course notes. We dedicate this book to our wives and to our parents for their constant support.
The reaction rate is the rate at which a species looses its chemical identity per unit volume. The rate of a reaction can be expressed as the rate of disappearance of a reactant or as the rate of appearance of a product. Consider species A:

The goal of the Process Systems, Reaction Engineering, and Molecular Thermodynamics program is to advance fundamental engineering research on the rates and mechanisms of chemical reactions, systems engineering, and molecular thermodynamics as they relate to the design and optimization of chemical reactors and the production of specialized materials that have important impacts on society.
The program supports the development of advanced optimization and control algorithms for chemical processes, molecular and multi-scale modeling of complex chemical systems, fundamental studies on molecular thermodynamics, and the integration of these methods and concepts into the design of novel chemical products and manufacturing processes. This program supports sustainable chemical manufacturing research on the development of energy-efficient chemical processes and environmentally-friendly chemical products through concurrent chemical product/process design methods. Sustainability is also enhanced by research that promotes the electrification of the chemical process industries over current thermally-activated processes.
