KL Model for Fine Particles

The following assumptions are made in addition to those in Section 23.3.2  

The continuity equations for the three main regions lead eventually to the performance equation for the reactor model. 

Eliminating cAc and cAe from equations 23.4-1 to -3, and dropping the subscript b from cAb, we obtain 

The fluidized-bed depth, Ljh is calculated from the fixed-bed packed depth, Lpa, as 

Equation 23.4-6 is one form of the performance equation for the bubbling-bed reactor model. It can be transformed to determine the amount of solid (e.g., catalyst) holdup to achieve a specified /A or cA
