• Low‐temperature Fischer‐Tropsch synthesis was investigated in micro packed‐bed reactors. Co/Re/γ‐Al2O3 catalysts with different particle shapes and sizes (60 to 580 μm) were employed. Tubular reactor geometry with lengths of up to 1 m was chosen. Pressure drop measurements in the absence of reaction and during reaction were carried out. For analysis of the experimental data a reactor model was developed, which was also used for the determination of liquid holdup. It could be observed that the liquid holdup is independent of conversion, reaction temperature, C5+ productivity, and reaction rate. For irregularly shaped catalyst particles, a liquid holdup in the range of 3 % was observed. Liquid holdup in micro packed‐bed reactors under Fischer‐Tropsch conditions was investigated. For this purpose, pressure drop measurements with and without reaction were carried out and analyzed with a reactor model. The liquid holdup is found to be independent of the conversion, the reaction temperature, and the reaction rate.
