Research progress of oxidation mechanism in the chloride process for titanium dioxide production

Chlorination is the main method of producing high-grade rutile titanium white. The products has good quality and the process is of low environmental pollution, high degree of automation, and low comprehensive energy consumption, and has the very high application value in the field of titanium white production and development prospects, but the oxidation reaction mechanism of titanium tetrachloride is still unknown. So the study of titanium tetrachloride oxidation reaction mechanism becomes a research and development focus. The paper elaborates the development, present situation and basic principle of the chlorination process. It is pointed out that the oxidation reaction mechanism of titanium tetrachloride has guiding significance for the oxidation reactor design and scale, the product morphology control and scar preventing. © 2018, Chemical Industry Press.
