✦ Synopsis

The mass transfer data measured m the hqmd flmd& beds of ion exchange resms m the Reynolds number range 0 22-6 4 are presented A comparison was made between the experunental results and the values predlcted by the recent theory of Nelson and Galloway and by the moddied theory proposed by Rowe The observed change of exponent on Reynoids number 1s prebcted by the theory of Nelson and Galloway, but this theory fads to pre&ct the correct dependance of Sherwood number of voldage The modtied theory proposed by Rowe predicts successfully the mass transfer coefficients at very low Reynolds number and m ad&bon It predicts also appro-tely the Reynolds number regon m which the change of exponent on Reynolds number IS observed, but It fads to predict the correct dependance of Sherwood number on voIdage m tis region INTRODUCI'ION Considerable attention was given to the experlmental

Mass transfer rates were determined in a 3.4cm id. trickle-bed reactor in the absence of reaction by absorption measurements and in presence of reaction. Gas flow rates were varied from O-100 I/h and liquid flow rates from O-l.5 I/h. The catalyst particles were crushed to an average diameter of 0.05

Liquid phase mass transfer coefficients for fihns in wave motion are considerably larger than predicted by previous theory. The increase in interfacial area due to waves cannot explain the discrepancy satisfactorily. A model for the absorption process has been proposed which takes into account eddie
