Abstract
The inclined rotating fixed-bed reactor with inner tube is a promising process intensification concept for gas-limited reactions. In order to take full advantage of the reactor concept the installation of an inner concentric displacement tube is proposed to support the wetting intermittency of the whole fixed-bed at different liquid filling levels. The effects of operating conditions and design parameters on flow stratification, liquid filling level and specific pressure drop are analysed to identify the process window. In particular, the influence of superficial phase velocities, inclination angle, rotational velocity, particle diameter and inner tube diameter are studied. The liquid phase distribution is characterized with a capacitance-based wire-mesh sensor, which is adapted to cope with organic liquid, porous alumina catalyst packings and reactor rotation. Furthermore, the radial porosity distribution in the annular fixed-beds is determined using gamma-ray computed tomography.
