粗四氯化钛除钒工艺现状及发展趋势

Status of process for removing vanadium from tetrachloride titanium and its development trends

概述了使用铜丝、有机物、硫化氢和铝粉4种物质除去粗四氯化钛中的杂质钒方法的优缺点,通过比较指出有机物除钒法和铝粉除钒法是较理想的粗四氯化钛除钒方法。最后,对有机物除钒法目前存在的问题及解决方案进行了分析。

The advantages and shortcomings of four processes for the removal of vanadium from tetraehloride titanium by virtue of copper wire, organic compounds, sulfide hydrogen and aluminium powder are reviewed. It is pointed out that the methods for vanadium removal by use of organic compounds and aluminium powder are more efficient ones by comparison. At last, the current problems in the above-mentioned method and their schemes for solution are analyzed.
