A fluidized bed reactor is a type of reactor or device which is used for carrying out a different type of multiphase chemical reactions. In this process to suspend the solid, a gas or liquid passes through a solid gritty material at higher velocities.
This process is used for solids to behave as, it was a fluid. The name of this process is fluidization, which introduce us with the so many important advantages to the FBR, because of these advantages now it is used in a wide range of industrial applications.

Other Applications:
The other applications of FBR technology are:- Fertilizers from Coal
- Industrial and Municipal Waste Treatment
- Oil Decontamination of Sand
- Radioactive Waste Solidification
Advantages of FBR:
- Ability to Operate Reactor in Continuous State
- Allows for continuous, automatically controlled operations.
- Catalyst is easily replaced or regenerated.
- Even temperature distribution eliminates hot spots.
- More efficient contacting of gas and solid than in other catalytic reactors.
- Uniform Particle Mixing
- Uniform Temperature Gradients
Disadvantages of FBR:
- Attrition, break-up of catalyst pellets due to impact against reactor walls, can occur.
- Can't be used with catalyst solids that won't flow freely.
- Catalyst may be deactivated.
- Erosion of Internal Components
- Erosion of reactor walls may occur.
- Expensive to construct and maintain.
- Increased Reactor Vessel Size
- Lack of Current Understanding
- Large pressure drop.
- Particle Entrainment
- Pressure Loss Scenarios
- Pumping Requirements and Pressure Drop
- Regeneration equipment for catalyst is expensive.
