Population Balance Model Simulation of the Particle Effect .

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.

Slurry reactors are most frequently used when a liquid reactant must be contacted with a solid catalyst, and when a reaction has a high heat of reaction. They may be used in such applications as hydrogenation, oxidation, hydroformation, and ethynylation. The reactor shown below is a slurry phase hydrogenation reactor.

Tubular reactors are used, for example, in the steam cracking of ethane, propane and butane and naphtha to produce alkenes. (b) Fixed bed reactors. A heterogeneous catalyst is used frequently in industry where gases flow through a solid catalyst (which is often in the form of small pellets to increase the surface area).It is often described as a fixed bed of catalyst (Figure 5).

Muroyama & Fan (1985) distinguished the three-phase fluidized-bed reactor from the gas-sparged slurry reactor. In the gas-sparged slurry reactor, the size of the solid particle is usually less than 100/xm in diameter, the volumetric fraction of the solids is less than 0.1, and particles are maintained in a suspended state by .

The objective of these studies was to perform a realistic evaluation of the relative costs of tublar-fixed-bed and slurry reactors for methanol, mixed alcohols and Fischer-Tropsch syntheses under conditions where they would realistically be expected to operate. The slurry Fischer-Tropsch reactor was, therefore, operated at low H{sub 2}/CO ratio on gas directly from a Shell gasifier.

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.
