粗四氯化钛除钒工艺进展及评价

Development and Evaluation of Process for Removing Vanadium from Crude Titanium Tetrachloride

综述了粗四氯化钛的铜丝除钒、有机物除钒、硫化氢除钒和铝粉除钒的优缺点,且概述了这些工艺的应用进展。最后,指出有机物除钒和铝粉除钒是比较理想的除钒工艺,并对这两种工艺在国内的研究和推广提出了建议。

The advantages and defects of four processes for the removing vanadium from crude tetrachloride ti tanium by virtue of copper wire, organic compounds, sulfureted hydrogen and aluminium powder are summarized. The application developments for these processes are also reviewed. At last, it is pointed out that the methods for re- moving vanadium by use of organic compounds and aluminum powder are more efficient. And the proposals are pre- sented to develop and generalize these two processes in China.
