FLUIDIZATION

Beds under these conditions are called turbulent beds(05) With further increases of gas velocity, eventually the fluidized bed becomes an entrained bed in which we have disperse, dilute or lean phase fluidized bed, which amounts to pneumatic transport of solids (06)coefficient has been obtained in a three phase fluidized bed extractor with the higher interfacial area due to the drop breakage caused by the turbulent nature of fluidizing solid particles using toluene/acetic acid/water and toluene/benzoic.

Fluidized bed reactor

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 .Two-phase modeling of a gas phase polyethylene fluidized , Two-phase modeling of a gas phase polyethylene fluidized bed , according to Table 3, the fluidized bed reactor of , and single-phase models for fluidized bed.

HYDRODYNAMICS OF THREE PHASE FLUIDIZED BED USING , ,Prediction of Minimum Fluidization Velocity in Three-Phase

A three-phase (gas-liquid-solid) fluidized bed is used to study the hydrodynamic characteristics (like pressure drop, minimum fluidization velocity, and bed expansion) of low density particle (wood) using water as liquid phaseimportance in the design of a three-phase fluidized bed is the minimum fluidization liquid velocity, U LmfIt represents the smallest superficial liquid velocity, which at a given superficial gas velocity brings particles in the bed from rest to motion A great deal of experimental work has been devoted, over the past 3 decades,4-30 to investigating the onset of fluidization in three-phase.
