Fluidized bed reactors (FBR) are catalytic reactors in which the catalyst is fluidized within the reactor. ADVANTAGES. DISADVANTAGES. Parr Fluidized Bed Reactors are used extensively in the chemical process industries. Compared to packed bed, a fluidized bed has notable advantages such as better control of temperature, no hot spot in the bed, uniform catalyst distribution and longer life of the catalyst. A number of fluidized-bed catalytic reactor models have been proposed during the past half-century based on conservation equations as well as empirical relations. In practice, each flow regime has its own advantages and disadvantages:.
