Embodiment 1
[0026] figure 1 It is a schematic process flow diagram of an embodiment of the present invention. The embodiment of the present invention is used to reclaim the vanadium element in titanium tetrachloride. The recovery process mainly includes: refining of titanium tetrachloride, reduction of vanadium oxytrichloride in titanium tetrachloride, The adjustment of vanadium content in titanium tetrachloride, the preparation of vanadium-containing sponge titanium, etc., when using the above process, include the following steps: first, do not add vanadium removal agent in the primary kettle, so as to prepare vanadium-containing refined tetrachloride Titanium, then add excess activated carbon to vanadium-containing refined titanium tetrachloride, VOCl 3 All reduced to VCl 3 According to the vanadium-containing sponge titanium requirement of 10% vanadium content, the vanadium content in titanium tetrachloride is increased to 0.75% by distillation, and this solution is added to the reduc...
