provide a more uniform fluidization. Wankhede US et al. [12]
found that acoustic energy of sufficient intensity and sound pressure
level significantly improved the quality of fluidization of fine
powders and heat transfer rates. In addition, Guo QJ et al. [13] reported
the influence of sound waves on fluidization of quartz
sand and SiO2 particles in high temperature fluidized bed. Raganati
F et al. [14,15] reported the influence of sound waves on fluidization
of CO2 adsorbents materials. Their observations showed that
the adsorption process of CO2 can be enhanced by reason of the
fluidization quality improvement of CO2 adsorbents materials.
