| 摘 要： | 开展不同类型脂肪酸精制四氯化钛试验研究,分析精TiCl_4样品和除钒尾渣。结果表明,饱和脂肪酸具有除钒效率较低、残渣分散性较好的特点,且碳链长度对除钒效率影响不大;不饱和脂肪酸除钒效率远高于相同链长的饱和脂肪酸,但是除钒泥浆黏度大、易结块;混合脂肪酸既可以保证除钒效率,也可以使残渣具有优良的分散性。

| Abstract: | The experiments of refining titanium tetrachloride using different fatty acids were carried out,and the samples of purified titanium tetrachloride and tailing slag for vanadium removal were analyzed.The results show that with saturated fatty acids as reagent the vanadium removal efficiency is lower and the tailing slag has an excellent dispersibihty.In addition,the length of carbon chain of saturated fatty acids scarcely affects the vanadium removal efficiency.The efficiency of vanadium removal by unsaturated fatty acids owning the same carbon chain length with saturated fatty acids,is more higher than that of saturated fatty acids,while the slurry for vanadium removal is more viscous and prone to agglomeration.Using mixed fatty acids as the reagent can not only guarantee the vanadium removal efficiency but also obtain the tailing slag with excellent dispersibility. |
