1. Importance of fluidized bed hydrodynamics

The hydrodynamic behavior of fluidized beds is described in detail in the article entitled Techniques de mises en contact entre phases solides et gazeuses (Techniques for bringing solid and gaseous phases into contact) [A 5 850] , in the journal Génie des procédés. However, it is worth recalling here some of the principles on which reaction models are based, as well as the methods that can be applied to the case of reactors with large dimensions (several meters).

1.1 Hydrodynamic behavior laws in fluidized beds

The passage of a gas through a layer of solid particles leads, depending on the surface velocity of the gas, to different fluidization regimes (figure
