Definitions
- electrolyses of this type have been carried out through particles beds set in motion, from time to time, in order to eliminate the clogging phenomenon.
- the electrical conduction at the heart of the bed then takes place in very poor conditions. conditions and densities of electrolysis current, much lower than in a fixed bed, lead to very insufficient material transfers to make this process applicable on the industrial level.
- Another objective is to obtain the above-mentioned effects without disturbing the selectivity of the reaction with respect to the deposited species.
- each volume electrode eliminates clogging phenomena, by separating and dislocating the particles which can no longer weld together, while operating in a fixed bed during the remainder of the cycle with speed reversal of the flow of electrolyte allows electrical conduction under satisfactory conditions inside the electrode.
- the delivery speed Vo will in practice generally be chosen much lower than the minimum fluidization speed Vmf (Vmf> 10 Vo) so that the fluidization is due only to the periodic pulsation superimposed on the flow.
- the solution to be treated is taken from a tank 15 by a gear pump 16 to be delivered at constant upward speed Vo through a flow meter 17 at the base 1b of column 1.
- Current leads are formed by conductive grids 23, 24, 25, 26 and 27.
