Physical chemistry of carbothermic reduction of aluminum: Final report
A program of study of carbothermic reduction of aluminum was undertaken to investigate the underlying physical chemistry of reactions and processes. The primary goal of the research was to establish the physicochemical basis by the use of which it may be possible to develop schemes for the production of aluminum by direct carbothermic reduction, thus avoiding the use of electrochemical means such as is exemplified by the Hall-Heroult process. One task of the program was to propose one or more possible schemes, and a specific challenge in the investigation was to determine whether or not a process based on the counter-current shaft furnace could possibly be practical for the production of aluminum. In such a furnace, combustion of a carbonaceous fuel would provide heat required in the process, and carbon would also serve as the reducing agent as is the case for the production of crude iron in the iron blast furnace. 15 refs., 22 figs., 24 tabs.
