Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. The industrial fluidized bed process ranges from simple applications like drying, cooling, pneumatic transport of powders, etc. The adaptation of the existing "Know How" and the handling of low calorific fuel in environmental technology led to sewage sludge incineration on a fluidized bed basis. Fluid bed dryers, as their name suggests, are used for drying materials such as granules, tablets, powders, fertilizers, and plastics. Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. Copyright © American Institute of Chemical Engineers. By the injection of air and gas, the sand is brought in a liquid-like state (suspended sand particles).
