2. Reaction models for fluidized beds
2.1 Model classification
Chemical reactions in fluidized beds fall into two distinct groups:
catalytic reactions ;
reactions with consumable solids.
Reactions with consumable solids are naturally more complicated to model, since they produce not only a change in the composition of the gas phase, but also modifications in the granulometry of the solid (in some cases) or its density (in others).
Generally speaking, the fluidized-bed reactor can be illustrated as shown in figure 3 , where several zones can be distinguished:
