AbstractFluidized‐bed reactors present a number of advantages that make them an attractive alternative in processes involving biocatalysts. However, fluidized‐bed bioreactors are also realtively complex, basically for two reasons. First, their use requires the biocatalyst, commonly cells or enzymes, to be immobilized into or onto a solid support ...

Fluidized bed membrane reactors
2014Fluidized bed membrane reactors are an extension or an improvement of a packed bed membrane reactor. The fluidized bed configuration allows a more uniform temperature due to the movement of particles even for very exothermic reactions and decreased concentration polarization.

Very vigorous mixing of the fluidized particles takes place just the distributor, and heat and mass can be exchanged very effectively between particles and the fluidizing gas because of the large surface area of the particles. The gas fluid bed is characterized by having good heat transfer properties between the fluidized layer and heating or cooling ...

In the last 20 years, significant improvements in the computational fluid dynamics (CFD) modeling have been made that allow the simulation of large-scale, commercial CFBs. Today, commercial codes are available that can model some of this behavior in large-scale, commercial units in a reasonable amount of time.
