The hydrodynamic behavior of a cocurrent gas‐liquid‐solid semifluidized bed was investigated. A separate investigation was performed on a packed bed and a fluidized bed under gas‐liquid flow conditions similar to that for the semifluidized bed. Parameters of the semifluidized bed under extensive study include pressure drop, gas holdup, onset liquid velocity for semifluidization, and the height of the packed bed section and the fluidized section. The pressure drop of the semi‐fluidized bed obtained experimentally was compared favorably with that predicted by the model equations.
