Sammanfattning

Kinetic studies of catalytic three-phase systems are traditionally performed in autoclaves operating batchwise, and the results are described with rate equations based on the simple Langmuir-Hinshelwood concept. This is not sufficient, as complex organic molecules react on the catalyst surface, and more advanced kinetic models and experimental techniques are needed. Semicompetitive and multicentered adsorption models have been applied to kinetic data, and transient step-response experiments have been carried out for various industrially relevant three-phase systems. The theoretical basis of the advanced kinetic concept is described and successfully applied to several industrially relevant processes, such as hydrogenation of aromatic components and aldehydes on commercial catalysts and enantioselective hydrogenation on modified catalyst surfaces.
