Without catalysts industrial production, research and environmental technology would all be unthinkable. Although 80% of all large-scale industrial processes are catalytic, many scientists and engineers limit themselves to proceeding on empirical lines. They frequently do not possess the basic knowledge for a systematic development and application of catalysts. This book treats both homogeneous and heterogeneous catalysis - whereby special emphasis is placed on idustrial processes while environmental aspects and economic data also receive their fair of attention. Each chapter includes many practical examples. What has been learned can be controlled by means of exercises. In this way it is now possible for the first time to study technological catalysis independently using this textbook with exercises. The practitioner will find valuable help, for instance information concerning statistical planning of research or the simulation of catalytic reactors.
