Abstract

A new tracer technique is reported for the determination of liquid-solid contacting efficiency and liquid holdup in trickle beds packed with small alumina particles. Holdup was a function of liquid mass velocity for both porous and nonporous packing. Contacting efficiency remained uniform at a level of 65%.
