The objective of this research was to determine the feasibility of catalyzing the chlorination of alumina using inexpensive catalytic substances. The chlorination kinetics of alumina in the presence of carbon were investigated for different forms of carbon and two different alumina particle sizes. The influence of catalysts such as ternary, naf, and cryolite were studied for different carbon materials. The following observations were noted: (1) sodium fluoride appears to be the most stable catalyst, (2) ternary catalyst is quite powerful initially but its catalytic activity diminishes gradually possibly because of progressive deactivation, and (3) cryolite is an intermediate catalyst that may be more desirable than naf in industrial applications.
