Considering the multiphasic reaction system, we initially analyzed the mass transfer characteristics to identify parameters for a microkinetically controlled reaction. Mass transfer from the gas to the liquid phase was excluded at low catalyst amounts (10 mg), additionally high impeller speeds (>700 rpm) ensure that the film diffusion limitation is overcome (Fig. ). Due to the flexible properties of the fine catalyst particles and their dynamic swelling ability in the solvated state, a clear prediction about possible pore diffusion limitations cannot be stated. Therefore, low metal loadings were aimed to avoid pore diffusion limitations.
