Zur Mikro- und Makrokinetik mehrphasiger heterogen-katalysierter Reaktionssysteme : Untersuchungen am Modellsystem der Ni-katalysierten Hydrierung von 1-Octen
Heterogeneous catalysis based upon multiphase reactions is a very important issue in the chemical industry. Various mass transfer resistances (gas-liquid, liquid-solid, pore diffusion) occur in such systems. This results in the fact that the effective rate of reaction is much lower than the …

Dynamisches Mehrphasenmodell mit hypoplastischer Materialformulierung der Feststoffphase
The numerical simulation of heterogeneous materials with solid and pore filling fluid phases becomes more and more important in different areas of engineering practice due to the availability of high performance computers. The classical application area of multiphase models is the investigation of …

New strategies for multiphase catalysis using supercritical carbon dioxide
The work reported in this thesis deals with the development of an effective strategy for the recycling of a multipurpose catalyst. An immobilized metal complex acts as a "catalyst cartridge" applicable in a variety of catalytic reactions without using any volatile organic solvents but only carbon …

Katalytische Hydrierung in Mehrphasensystemen auf Basis von ionischen Flüssigkeiten und Kohlendioxid
Carbon dioxide (CO2) and ionic liquids (ILs) have been intensively studied as solvents in catalysis. The combination of ILs and CO2 and its interaction with third components has attracted only sparse interest in research. In the literature, the IL/CO2 system is discussed as a promising technique …
