A new electrolysis cell, the radial PPPE, in which the solid cathode is able to circulate continuously through the cell by pulsation, is described. The behaviour of the liquid and solid phases is analysed to understand the operation of the cell and the effect of pulsation. Two distinct regions are observed in the solid cathode during the upward pulsation: a stable upper and a destabilized lower region. The circulation in the upper region, segregation in the lower region and exchange between the two regions are characterized experimentally as a function of the maximum fluidizing height bed. Electrodeposition occurs in both regions. The RTD of the solid particles was determined.

    During two-phase electrolysis, bubble production occurs at one or two electrodes. This yields a large change for the electrolyser electrical and hydrodynamic properties. Under normal Earth gravity, the bubble production at the electrodes induces a macro-convection in the electrolyser. This leads...
