From a theoretical comparison of continuous low flow and stop-flow operation the latter method was found to be an attractive mode of interfacing.
Without gas flow, i.e. single-liquid trickle-flow operation, the reactor pressure has no influence on the dynamic liquid hold-up, which can be well correlated by means of the Reynolds and Galileo numbers.
For cross-flow operation, the correction factors are function of flow rate, mass-transfer area, distribution coefficient and overall mass-transfer coefficient, and some values of them are given graphically.
A major obstacle in the design of Jet-Loop Reactors in three phase flow operation is the calculation of the power demand, gas- and solids hold-up and loop velocity due to the pressure drop of the suspension.
As described in the logical flow, operation by the user is fairly linear and straight forward.
This work points out the benefits that can arise from the use of the reverse-flow operation, namely the decrease of the hot-spot temperature and the more favourable temperature distribution along the bed.
The formation of microfilms and the flow operation allowed for a safe and controllable production of the bioactive endoperoxide ascaridole.
The experiments show that in the case of two-phase flow operation at elevated pressures the hold-up decreases at relatively low gas velocities and even more so at higher pressures.
The proposed simulation of the reversed flow operation of a fixed-bed reactor for methanol synthesis is based upon a heterogeneous one-dimensional model.
The presence of static mixers is shown to give near-ideal plug-flow operation for the experimental conditions of this study.
