Abstract

Titanium tetrachloride with 98% purity was successively synthesized by chlorination of upgraded titania slag (88% TiO2, 2.9% Fe2O3) using chlorine gas in the presence of activated charcoal at 1173–1373 K in a fluidized bed chlorinator. The different parameters affecting the chlorination processes such as carbon source, carbon amount, temperature and time of chlorination were studied. Moreover, kinetics of chlorination of upgraded titania slag was studied. The results showed that the chlorination of upgraded titania slag was mainly controlled by diffusion of chlorine gas with calculated apparent activation energy of 11.9 kJ/mole.
