This paper presents the understanding of an electrochemical conical fixed bed reactor. The assumed chemical model has been cooper deposition from diluted solutions in (1 N) H2SO4. In this work a special emphasis is placed on the specific features of this type of reactor. The numerical solution of the differential equations, obtained from the mass and charge balances, provides us with the knowledge of concentration and potential distribution within the porous bed and permits determination of a reactor design diagram for a both cases of upward (cathode towards anode) and downward (anode towards cathode) percolation.
