Theoretical Production of Aluminum
Let’s consider the alumina reduction reaction:
This reaction involves the flow of 6 moles of electrons from the cathode to the anode to produce 2 moles of aluminum.
This means that, to produce 2 moles of aluminum atoms, which weight:
are involved 6 moles of electrons, hence 6 Faradays of electrical charge:
Combining the (1) and (2) for each Coulomb of electrical charge flown into the electrolyte are produced:
So, in 24 hours a cell with a line current of I amperes produces:
