Slurry reactors. Another way to alleviate the poor heat transfer problem of packed-bed reactors is the use of slurry reactors. The slurry is a mix of catalyst particles (10–200 μm) and product oil at about 35% in a reactor (in Figure 7-19). Reaction heat is removed by internal cooling coils that generate steam.

Comparison between fluidised bed and packed bed reactors .

Mathematical modelling of both fluidised and packed bed reactors has been carried out. In the fluidised bed reactor, a two-phase bubbling bed model has been used in order to estimate the interaction between gas bubbles and the dense phase in the bed. Modelling in the packed bed reactor was carried out based on that used by Ranade and Evans.

The basic reaction and transport steps in trickle bed reactors are similar to slurry reactors. The main differences are the correlations used to determine the mass transfer coefficients. In addition, if there is more than one component in the gas phase (e.g., liquid has a high vapor pressure or one of the entering gases is inert), there is one .

Conventional drag models were usually developed for gas‐liquid systems without considering the presence of particles in slurry‐bed reactors. A modified drag model is proposed by taking into account the effect of particles. Simulation results proved the accuracy of the model in predicting hydrodynamics in the slurry bed.
