Liquid distribution in trickle‐bed reactors: Part I. Flow measurements

Radial liquid distribution was measured for concurrent downflow of air and water through beds packed with catalyst particles. The experimental results can be predicted by a theory involving two parameters, a spreading factor S and wall factor f. Criteria are presented for predicting operating conditions (particle size and shape and tube diameter) for which the equilibrium distribution will be uniform and packed-bed depth required to attain equilibrium liquid distribution.
