A simple model for the description of #ow behavior in three phase (solid}liquid}gas) airlift reactors (TPAL) was developed. Based on an energy balance, which takes into account the dissipation of energy in the phase interfaces, the model predicts liquid and solid circulation velocities, gas holdup a
The use of mixed axial and radial flows in a fixed-bed adiabatic reactor can lead to regions of flow "back-up" in the bed. These regions cause temperature hot-spots to appear, even under conditions where there are none for a purely radial flow. The hot-spots can be reduced by balancing axial and rad
