Fibrous structured catalytic beds for three-phase reaction engineering - Hydrodynamics study in staged bubble columns

Woven fibrous materials are proposed as structured catalysts for three-phas e catalytic reactors. The design of a catalytic bed arranged as a plate bub ble column is discussed. The hydrodynamic parameters, like pressure drop an d liquid hold-up were found to depend on the woven structure of the fibrous layers and are shown to be a function of the distance between the threads in the fibres.
