The object of this study is to observe the fluidization behavior of liquid-solid and gas-liquid-solid fluidized beds with magnetic immobilized enzyme support particles as the solid phase in a uniform magnetic field. The voidage of the liquid-solid beds and the average gas holdup and the radial distribution of holdup of the gas-liquid-solid bed in the magnetic fields were measured and correlated using empirical models. Fluidization in a magnetic field was also used in a immobilized-cell catalyzed reaction system to test its applicability. The fluidized bed in magnetic field may find wide use in immobilized enzyme-catalyzed processes. Some authors have studied the fluidization characteristics of the gas-solid fluidized beds. However, the hydrodynamic behavior of L-s and g-L-s beds has seldom been investigated.
