PROCESS FOR PRODUCING TITANIUM TETRACHLORIDE USING LOW-GRADE TITANIUM RAW MATERIALS

摘要

Provided is a process for producing titanium tetrachloride using low-grade titanium raw materials. The process comprises adding the low-grade titanium raw materials into a furnace, heating the furnace to 420±40?, continuously adding the low-grade titanium raw materials, feeding chlorine into the furnace to begin the reaction, controlling the temperature of the furnace at 600?-700?, collecting the gases containing titanium tetrachloride generated in the reaction, condensing the gases to obtain a titanium tetrachloride liquid and a tail gas, taking the reacted inert chlorination residues out of the furnace depending on the amount of the materials being added, and processing and discharging the remaining residue when the reaction is completed. The content of titanium carbide in the low-grade titanium raw materials is 6%-16%, and preferably 7%-12%.
