The fluidized bed used in this work is a glass vessel, 2.9 inches in diameter. As the gas flows through the fluidized bed, the bed acts as a porous medium at low flow rates. Once the flowrate is high enough for the weight of the beads to be balanced by the drag, the beads become mobile and are termed fluidized.

Fluidized bed reactor — Wikipedia Republished // WIKI 2

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. This process, known .
