This up-to-date textbook fills a longstanding gap for graduate courses in chemical reaction engineering. It explores the interplay between transport processes and reaction kinetics, multiphase reactions and reactors, and optimization and reactor stability. The book includes a brief review of major concepts, describes chemical kinetics and its relation to thermodynamics and transport phenomena, and addresses reactor classification and reactor design for increasingly complex situations. It helps readers to develop the facility to apply engineering analysis to a representative spectrum of industrially important reaction engineering problems.
