In this book, the authors explain how the basic concepts of chemical reaction engineering and transport phenomena are applied to the design of catalytic combustion systems. It starts with a description of applications where catalytic combustion is already utilized, terminology is described and the interactions between heat, mass and momentum transfer, and the reaction chemistry are explained. Basic principles in thermodynamics, kinetics and transport phenomena are described before they are utilized in mathematical models of catalytic combustors. Some advice is provided on the selection of suitable numerical techniques and the importance of recognizing gas phase homogeneous reactions. Guidance is also provided on experimental techniques, whether for chemical kinetic or pilot scale studies. Throughout the text there are plenty of worked examples, and in the final chapter the application of modelling techniques to the solution of practical problems is described. This book is suitable for both the novice looking for basic guidance and those seeking more advanced information.
