Comparison of rotating bed reactor (RBR) technology and fixed bed reactor (FBR) column during activated carbon decolourization. The more efficient use of the adsorbent with a SpinChem® RBR enabled completion of the process within 40% of the time at the same material amount or allowed reduction to 50% material while still being able to finish the process within the same time as the FBR.

Fluidized bed reactor - Wikipedia

Fluidized bed reactor - Wikipedia

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 speeds to suspend the solid and cause it to behave as though it were a fluid.

Rotating Packed Bed - an overview | ScienceDirect Topics

Rotating packed bed (RPB) reactor was introduced to enhance the mass transfer among the gas–liquid–solid phases in carbonation process (Fig. 2.7) (Pan et al., 2016; Pei et al., 2017).RPB reactor can provide a centrifugal force by centrifugally rotating the rotary bed. The centrifugal acceleration is much greater than that of the gravity force.
