Abstract
A chlorine-containing gas is introduced as an upward flow into a vertical, upwardly widening column-type reactor, and a titaniferous material and a solid carbonaceous reducing agent are charged into the reactor at its upper and lower parts to effect chlorination in a dilute-phase fluidization system accompanied by reflux of part of the solid materials and thereby yield titanium tetrachloride.
