Kinetics of Catalytic Reactions

Describes how to conduct kinetic experiments with heterogeneous catalysts, analyze and model the results, and characterize the catalysts§Detailed analysis of mass transfer in liquid phase reactions involving porous catalysts. §Important to the fine chemicals and pharmaceutical industries so it has appeal to many researchers in both industry and academia (chemical engineering and chemistry departmentsThis textbook contains all the information needed for graduate students or industrial researchers to design kinetic experiments involving heterogeneous catalysts, to characterize these catalysts, to acquire valid rate data, to verify the absence of mass (and heat) transfer limitations, to propose reaction models, to derive rate expressions based on these models and, finally, to assess the consistency of these rate equations.§Langmuir, Freundlich, and Temkin isotherms are derived and the former are used in Langmuir-Hinshelwood (and Hougen-Watson) models, as well as reaction sequences without a rate-determining step, to obtain rate expressions on uniform surfaces. In addition, rate equations based on non-uniform (Temkin-type) surfaces are examined as an alternative approach. The most recent technique to calculate heats of adsorption and activation barriers on metal surfaces, the BOC-MP approach, is discussed in detail. Methods to measure metal surface areas and crystallite sizes using x-ray diffraction, transmission electron microscopy and various chemisorption techniques are discussed. Different experimental techniques to determine the influence of mass transfer limitations, especially within the pores of a catalyst, are reviewed in detail, with a particular emphasis on liquid-phase reactions.§Many illustrations of these and other topics are provided along with numerous problems and a Solutions Manual for instructors. This book will be applicable to any graduate course in chemical engineering, chemistry or materials science that involves kinetics of catalytic reactions, including those catalyzed by enzymes.This advanced undergraduate/graduate textbook teaches readers to design kinetic experiments involving heterogeneous catalysts, to satisfactorily characterize these catalysts, to acquire valid rate data, to determine the presence or absence of heat and mass transfer limitations in these data, to select and simplify reaction models, to derive rate expressions based on these models, and to assess the consistency of these rate equations. A special emphasis is placed on assessing mass transfer effects, particularly in liquid-phase reactions. Sufficient background information and discussion of the assumptions related to the derivation of adsorption isotherms and reaction models has been provided to allow the reader to understand the limitations of these models and to feel comfortable in their application. Both ideal and nonideal surfaces are considered, and enzyme catalysis is also discussed. There are numerous worked-out examples, and homework exercises.§The book will be used as a textbook in courses in kinetics and/or catalysis and also as a supplement in advanced undergraduate chemical engineering courses on kinetics and reactor design, as well as a guide for researchers in catalysis in industry. The most probable discipline for its use is chemical engineering, but it can also be used in materials science, fuels science, and chemistry programs.§Many new practitioners in catalysis today are involved singularly or in small groups at small entrepreneurial companies around the world, especially in the United States. This book should be a tremendously useful reference book as these scientists design runs with heterogeneous catalysts, interpret their experimental data, and model the kinetics to describe their results
