Our field of research is the chemical reaction engineering. Important subjects are the the investigation of reaction kinetics and the development of new reactors and processes for the chemical industrie. The control of the activity and selectivity of catalysts by emplacement in microstructured enviroments deserves special attention. In case of homogeneous catalysts, microemulsions or micells are used to optimize the reaction parameters simultaneous and recycling of the catalysts. For heterogeneous catalalysts, used for partiel hydrogenations or oxidations with fast consecutive reactions, diaphragm as the catalyst-holder are analysed. The fundament of all concepts is the full kinetic investigation and modeling like it is happen in case of the partiel oxidation of small hydrocarbons for the time being.
