The kinetics of the carbochlorination of titania slag with chlorine gas and petroleum coke were determined. The porosity created, when easily chlorinated components of the slag such as iron oxide are rapidly reacted, had a significant effect on the chlorination of the slag. The effects of temperature, chlorine partial pressure, and initial particle size were determined, and a rate equation that incorporates these effects in the ranges of experimental conditions used in this work was developed. The results of this work show that the chlorination kinetics of titania slag are quite different from those of rutile with which most previous studies were concerned.
