This study aims to investigate the dynamic parameters of pseudo homogenous mixtures of aluminum pillared clay and ferromagnetic steel particles (APC-FMS) in classic fluidization and in fluidization stabilized in coaxial magnetic field. For both dynamic conditions of fluidization the structure of the bed was important in order to enhance a quasi homogeneous structure and to prevent the segregation of the particles in the bed. The minimum fluidization velocity, the minimum pressure drop, the bed expansion height and the minimum bubbling velocity were determined for mixtures that contain 0.35, 0.55 and 0.75 mass fraction of magnetic particles. The optimal dynamic conditions were established in order to ensure a higher contact surface between the solid particles and the fluidization gas. This is useful in the mass transfer processes like adsorption of residual gases when the preservation of energy consumption is necessary.
