Liquid-solid transfer coefficient by an electrrochemical technique

Written by sctunisie no comments

The paper proposes a fonctionnement of a fixed bed electrochemical reactor. The limiting current technique is used to obtain the liquid - solid mass transfer coefficient. The porous electrode is made of copper particles which are percolated by a dilute solution of Cu++ ions in a sulfuric acid medium. We found a correlation between the Reynolds number Re and the Sherwood number Sh : Sh = 2,1 Re0,35 Sc0,33. This correlation is compared with empirical ones obtained by several authors and is in good agreement with them.
