Effect of gas velocity and bed mass on liquid minimum fluidization velocity in a three-phase fluidized bed with cylindrical particles

摘要

Gas-liquid-solid fluidization also known as three-phase fluidization is a subject of fundamental research,since the last three decades due to its industrial importance Three-phase fluidized beds have been applied successfully to many industrial processes such as in the H-oil process for hydrogenation and hydro-desulfurization of residual oil,the H-coal process for coal liquefaction,Fischer-Tropsch process and the bio-oxidation process for wastewater treatment.
