Abstract

L'invention se rapporte à la chimie minérale industrielle. Elle concerne un procédé de fabrication de dioxyde de titane par oxydation du tetrachlorure de titane à haute température, caractérisé en ce que l'on introduit le tétrachlorure de titane dans au moins deux zones d'alimentation du réacteur d'oxydation, à raison d'au moins 1 % du tétrachlorure de titane dans la première zone d'alimentation. Utilisation par l'industrie chimique en vue de réduire les dépenses d'énergie.The invention relates to industrial mineral chemistry. It relates to a process for manufacturing titanium dioxide by oxidation of titanium tetrachloride at high temperature, characterized in that the titanium tetrachloride is introduced into at least two feed zones of the oxidation reactor, at a rate of at least 1% of the titanium tetrachloride in the first feed zone. Use by the chemical industry to reduce energy costs.
