Problems solved by technology
[0002] The preparation of titanium dioxide by vapor phase oxidation of titanium tetrachloride is an advanced titanium dioxide manufacturing process, commonly known as the chloride titanium dioxide production process. Because of the advantages of good product quality and environmental friendliness, this process is widely used in developed countries, but due to Technology blockade, the application of this process in China needs to be developed, one of the reasons restricting the development is the lack of key parameters of the process
Due to the high reaction temperature and high pressure, the process has extremely high requirements on the production equipment, and it is difficult to achieve such strict conditions in the laboratory

Description
technical field [0001] The invention relates to an experimental reaction system for preparing titanium dioxide by vapor-phase oxidation of titanium tetrachloride, belonging to the technical field of titanium dioxide by chloride method. Background technique [0002] The preparation of titanium dioxide by vapor phase oxidation of titanium tetrachloride is an advanced titanium dioxide manufacturing process, commonly known as the chloride titanium dioxide production process. Because of the advantages of good product quality and environmental friendliness, this process is widely used in developed countries, but due to Technology blockade, the domestic application of this process needs to be developed, and one of the reasons restricting the development is the lack of key parameters of the process. Laboratory-level experiments can obtain key parameters at a relatively low cost, but due to the complex experimental conditions of titanium tetrachloride gas-phase oxidation, the require...
