Resumen:
Liquid phase hydrodynamics is studied in a three-phase fixed bed with cocurrent upflow of gas and liquid. Residence-time distributions are measured to determine liqid hold-up and backmixing using different liquids and glass beads of two sizes. Two types of correlations are tested for liquid saturation. Correlations based on the drift flux concept are found to account for experimental results. liquid mixing is described
