| 摘要 |
There is disclosed an electrochemical process wherein an electrolyte is passed through one electrode compartment of an electrochemical cell, said one electrode compartment comprising a particulate electrode and being separated from a second electrode compartment of said electrochemical cell containing a counter-electrode by a separator having an ion-permeable wall inclined away from the vertical and towards the particulate electrode. The distribution of the particles of said particulate electrode in the electrolyte during the process is controlled in a manner such that there is formed within said one electrode compartment a first region which is adjacent to the ion-permeable wall and within which first region substantially all the particles are, for a large proportion of the time they spend in said first region, separated from each other, and a second region which is spaced from the ion-permeable wall and within which second region substantially all the particles are, for a large proportion of the time they spend in said second region, in contact with other particles, and substantially all the particles are circulated between said first and second regions.
