Abstract

The invention discloses a method for producing titanium tetrachloride by using a low grade titanium material, and belongs to the chemical technical field. The technical problem to be solved is to provide a method for producing titanium tetrachloride by using the low grade titanium material in continuous industrialized production. The method is characterized in that the low grade titanium material containing a certain proportion of titanium carbide is adopted to directly react with chlorine at the temperature of 600 DEG C to 700 DEG C to produce titanium tetrachloride. Long period continuous stable operation can be kept by using the technological parameters of the invention, and chlorination rate of titanium carbide in titanium material reaches above 90 percent, so that the titanium can be better used for producing titanium tetrachloride.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a process for producing titanium tetrachloride by boiling chlorination, in particular to a method for producing titanium tetrachloride by using low-grade titanium raw materials. Background technique [0002] With the rapid development of the world's titanium industry, titanium ore resources have become one of the important factors restricting the titanium industry. Since high-grade titanium ore resources were exploited in large quantities in the early stages of the development of the titanium industry, currently there are fewer and fewer high-grade titanium ore resources, and the production areas are also very concentrated, monopolized by a few large groups, while low-grade titanium ore resources are widely distributed. , exist in various forms and have large reserves, so the development of boiling chlorination process for low-grade titanium raw materials can not only solve the curr...
