This is the Third Edition of the standard text on chemical reaction engineering, beginning with basic definitions and fundamental principles and continuing all the way to practical applications, emphasising real-world aspects of industrial practice. The two main sections cover applied or engineering kinetics, reactor analysis and design. Includes updated coverage of computer modeling methods and many new worked examples. Most of the examples use real kinetic data from processes of industrial importance. Early chapters teach students how to benefit from the application of quantum chemical methods to real Processes. The single event concept is introduced and applied to commercial vacuum gas oil hydrocracking.
