Název v původním jazyce

Mathematical model of a secondary current density distribution in the segmented thin-gap flow-through electrosynthesis cell

Popis výsledku v původním jazyce

An application of microstructured systems is supposed to be a promising way to improve chemical reactors performance. The main advantage of these systems consists in a local control of the process parameters. From the electrochemical point of view this approach allows to control local electrode current density and thus operate cell near the optimal process conditions. Such behaviour can be attained e.g. by segmentation of the working electrode. It leads to a process with the higher single-pass conversion and due to the higher process efficiency to the easier products separation. In this work the detailed two-dimensional steady-state calculation of the primary and secondary local potential and current density distribution in a single-pass high-conversion segmented cell is presented. The rectangular cell with the anode divided into 10 segments was treated. The calculations performed have confirmed a significant impact of the geometrical factors of the rectangular cell, as well as the inf
