High-temperature heterogeneous equilibria in the unit activity approximation: I. alumina-carbon-chlorine system

Coal ash can become an important mineral substitute for the recovery of several metals, especially aluminum and titanium. A plausible route for the recovery could be via high temperature chlorination in the presence of a reducing agent. The thermodynamics of the reaction system for the free energy computations consisted of 135 chemical species containing 12 elements, namely Al, C, Ca, CI, Fe, K, Mg, Na, O, S, Si and Ti. The results indicate that the chlorination route is feasible over a wide temperature range.
