Modelagem de um reator eletroquímico de configuração perpendicular utilizando eletrodos de aço-316 e DSA (Ti/Ru0,3Ti0,7O2)® expandido.

Abstract

This work aimed to study the mass transfer in a tubular electrochemical reactor of the type PFR (Plug Flow Reactor) Flow-by configuration, using commercial electrodes formed by perforated plates in stainless steel-316 (control electrode) and plate Extended DSA (Ti|Ruo,3Ti0,702)® (working electrode). For this was the technique of electrochemical electroredution of potassium ferricyanide ion in alkaline medium, under diffusional control. The relationship between the influence of hydrodynamic flow on the mean coefficient of mass transfer was established from the application of the Buckingham TT theorem. The empirical model found in this work expressed by the relationship between the Sherwood number and Reynolds number, was compared with other models in the literature. The comparative analysis revealed a pattern similar to that found for an electrochemical reactor of the type filter-press operating in the laminar, fully developed. ®DE NORA
