Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. This allows for extensive mixing in all directions. A result of the mixing is excellent temperature stability and increased mass-transfer and reaction rates. Fluidized bed reactors are capable of handling large amounts of feed and catalyst.

Although fluidized bed reactors are mainly used for large-scale applications (see Chapter 8), they can also be used for laboratory or bench-scale tests of a catalyst and so they will be discussed briefly in this chapter.If small catalyst particles are placed in a packed bed, severe pressure drop problems can be encountered, especially if higher gas flow rates are used.

Fluidized Bed Reactors. Parr Fluidized Bed Reactors are used extensively in the chemical process industries. The distinguishing feature of a fluidized bed reactor is that the bed of solid particles or catalyst is supported by an up flow of gas.

Catalyst attrition has often been a major obstacle in the development of new fluidized‐bed processes and it is still of concern for existing processes whenever the catalyst is changed. The main consequence of attrition is the generation of fines and the resulting loss of valuable material.Cited by: 81

Dehydrogenation of isobutane to isobutene over supported gallium oxide microspherical catalysts was investigated in a fluidized-bed reactor. A partially crystallized nanostructured aluminum hydroxide-oxide, which is a product of gibbsite centrifugal thermal activation (CTA) obtained using a CEFLAR technology, was used as a catalyst support. The structural and textural properties of Ga2O3/Al2O3 ...Cited by: 5

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough velocities to suspend the solid and cause it to behave as though it were a fluid.

Effect of the improvement in catalyst supports on catalytic activity is tested in a micro fixed bed reactor. And then in a cold model, fluidization characteristics of pelletized catalysts are studied. Finally, the process is operated in a lab-scale Gas-Solid-Solid fluidized bed reactor.
