Preliminary thermodynamic assessment of processes to produce aluminum using aluminum sulfide as an intermediate product
New processes for the production of aluminum, which use aluminum sulfide as an intermediate product, are described. According to thermodynamic data and equilibrium compositions calculated from a NASA-Lewis code, the energy required for the production of aluminum by such a process is much lower than that of the present Hall-Heroult process or the new process under development at Alcoa (AlCl/sub 3/ electrolysis). Future studies are recommended on the technical feasibility and economics of aluminum sulfide processes for producing aluminum.
