The chemical reactor represents the core of chemical reaction engineering. The design and optimization of these reactors require interdisciplinary knowledge and skills, which can often be used in a similar way in other unit operations. First of all a methodical overview of the various reactor types is given. In the following fundamental course the associations between physical chemistry, thermodynamics and kinetics are compiled. The treatment of idealized reactor systems, stirrer tanks, idealized current pipes and cascades of idealized reactors, both disregarding and considering the effects caused by the heat of reaction are investigated. The location and stability of the operation points in continuously flowed stirrer tank are analyzed as a function of the operation parameters. As an essential non-ideality the residence time properties, its determining, mathematical modelling and its influence on the degree of conversion, selectivity and efficiency are discussed. Secondary the lecture gives attention to multiphase reaction systems and the interaction between mass transport and chemical reaction. Among other things heterogeneous catalyzed systems and the important field of the acceleration of mass transport in gases and fluids caused by chemical reactions are discussed. The lecture is completed by numerous practical examples.
