Significant experimental and theoretical efforts have been carried out in order to predict liquid holdup in cocurrent downflow packed-bed reactors, especially under trickle flow conditions. One of the most widely methods employed for holdup measurements has been the draining technique. However, to our knowledge, only few papers have performed a quantitative analysis of the drainage phenomena .The aim of the present work is concerned with the study of the drainage in a catalyst bench-scale packed bed under typical liquid superficial vclocities characterizing trickle-bed flow regime, in theparticular case of stagnant gas flow, its quantitative description and modeling .
