The kinetics of the carbochlorination of titania slag with chlorine gas and
petroleum coke were determined. The porosity created, when easily chlorina
ted components of the slag such as iron oxide are rapidly reacted, had a si
gnificant effect on the chlorination of the slag. The effects of temperatur
e, chlorine partial pressure, and initial particle size were determined, an
d a rate equation that incorporates these effects in the ranges of experime
ntal conditions used in this work was developed. The results of this work s
how that the chlorination kinetics of titania slag are quite different from
those of rutile with which most previous studies were concerned.
