conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

The fluidization behavior of silica gel was tested in a fluidized bed under different sound pressure levels and sound frequencies. It has been found that the particle mixtures can be fluidized smoothly with sound assistance at low sound frequency owing to the sound energy disrupting large size of agglomerates. The minimum fluidization velocity was found to decrease with increasing sound frequen...

The fluidization and reduction behavior of micron-sized iron oxide powder, produced by combustion, is studied in a lab-scale cylindrical fluidized bed. minimum velocity umf found to stabilize above normalized static bed heights 0.5 H/D (static height divided the diameter). measured as function temperature between 280 860 K for both H2 N2 fluidizing gas. experimental results start deviate from E...
