【Abstract】 Natural rutile and gaseous chlorine with carbon as reductant were used to prepare titanium tetrachloride. Thermodynamics and kinetics of chlorination of Kenya natural rutile particles in a batch-type fluidized bed were studied at 1173-1273 K. Thermodynamic analysis of this system revealed that the equation of producing CO was dominant at high temperatures.

Production of titanium tetrachloride (TiCl4) from titanium ...

Rutile ore grade gives a yellow or pale-brown streak. For pro-duction of titanium, there are diverse types of rutile with larger amounts of iron, but they are not as fa-vorable as the high-purity rutile [1]. Some minor ores include nigrine, ilmenorutile, seyenite, brookite, and anatase [1, 15]. The second important ore of titanium is ilmenite

Modelling TiO2 production by explicit use of reaction

This chapter discusses modeling TiO2 production by explicit use of reaction kinetics. Titanium dioxide (TiO2) is a bulk commodity, which is used as a white pigment, for paints, plastics, paper, and rubber. TiO2 pigment is produced by two major industrial routes from its ore, which is either ilmenite or either natural or synthetic rutile.
