Effect of the liquid axial dispersion on the behavior of fixed bed three phase reactors

Mostrar otras versiones (1)

The role of the liquid phase axial dispersion in fixed bed three-phase reactors behavior is examined by the formulation of a mathematical model including the major hydrodynamic and mass transport phenomena occurring in these reactors. Furthermore, liquid axial dispersion is evaluated from experiment...

520 3 |a The role of the liquid phase axial dispersion in fixed bed three-phase reactors behavior is examined by the formulation of a mathematical model including the major hydrodynamic and mass transport phenomena occurring in these reactors. Furthermore, liquid axial dispersion is evaluated from experiments carried out in mock-ups for cocurrent downflow and upflow. The effect of the liquid axial dispersion is analyzed by considering either liquid reactant of gaseous reactant limited reactions. A general criterion valid in both cases is developed in order to evaluate when it is necessary to take into account the axial dispersion effect. © 1992.  |l eng
