We present the use of supercritical CO 2 (scCO 2 ) as reaction solvent in a packed bed silicon/glass microreactor in case of the hydrogenation of cyclohexene as a model reaction. In situ phase studies in the continuous flow of the reaction mixture, h

We used optical methods such as Laser Induced Fluorescence (LIF) and confocal Laser Scanning Microscopy (LSM) to characterize gas–liquid phase distribution in rectangular microchannels. Using a 2 m long microchannel with a hydraulic diameter of 200

To increase mass transfer in solid catalyzed gas–liquid hydrogenations, the reactions are often operated at high pressures. Silicon/glass microreactors present a possibility to safely handle high-pressure and provide optical access into the reactio

We present a method for measuring the residence time distribution (RTD) in microfluidic systems. A piezoelectrically actuated sample injector releases approximately 100 nl of tracer liquid into a microchannel of rectangular cross section. The spreadi

Raman spectroscopy on a chip based Si/glass microreactor allows fast and simultaneous analysis of concentration profiles and phase behaviour of a heterogeneously catalyzed reaction at high pressure.

We use micro particle image velocimetry (microPIV) and fluorescence microscopy techniques to characterize microscale segmented gas-liquid flow at low superficial velocities relevant for chemical reactions with residence times of up to several minutes
