Energetic analysis of the liquid-to-wall mass transfer in a trickle bed reactor

This paper presents an experimental study of the liquid/solid mass transfer at the wall of a trickle bed reactor operating in the high interaction reg imes (pulsing and dispersed flow). The influence of Schmidt number was main ly investigated. The experimental results were interpreted using energy dis sipation in terms of Kolmogoroff numbers. It was shown that the wall-to-liq uid mass transfer coefficient can be correctly predicted by the following c orrelations: (i) in pulsing flow: Sh phi Sc-1/3 = 0.25(Ko)(0.25) (ii) in dispersed flow: Sh phi Sc-1/3 = 0.41(Ko)(0.23).
