TAILIEUCHUNG - CHEMICAL REACTOR DESIGN

When analyzing kinetic data or designing a chemical reactor, it is important to state clearly the definitions of reaction rate, conversion, yield, and selectivity. For a homogeneous reaction, the reaction rate is defined either as the amount of product formed or the amount of reactant consumed per unit volume of the gas or liquid phase per unit time. We generally use moles (g mol, kg mol, or lb mol) rather than mass to define the rate, since this simplifies the material balance calculations. | CHEMICAL REACTOR DESIGN Peter Harriott Cornell University Ithaca New York DEKKER Marcel Dekker Inc.

Current printed last digit 10 9 8 7654321 PRINTED IN THE UNITED STATES OF AMERICA Copyright 2003 by Taylor Francis Group LLC Preface This book deals with the design and scaleup of reactors that are used for the production of industrial chemicals or fuels or for the removal of pollutants from process streams. Readers are assumed to have some knowledge of kinetics from courses in physical chemistry or chemical engineering and to be familiar with fundamental concepts of heat transfer fluid flow and mass transfer. The first chapter reviews the definitions of reaction rate reaction order and activation energy and shows how these kinetic parameters can be obtained from laboratory studies. Data for elementary and complex homogeneous reactions are used as examples. Chapter 2 reviews some of the simple models
