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.

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 .

Classification of three-phase reactors

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 .
