中文摘要: 利用HSC软件计算了硫在熔盐氯化过程中发生化学反应的标准吉布斯自由能,研究了石油焦中硫含量对粉磨性质、熔盐氯化过程控制、粗四氯化钛质量和精制除杂的影响。结果表明,硫在熔盐氯化体系中的主要反应产物是SO2、COS、SO2Cl2和SOCl2;硫含量不会影响熔盐氯化过程连续稳定运行,但会导致熔盐、收尘渣、尾气和粗四氯化钛中硫含量增大;硫在精制过程中难以除去,应选择硫含量低于0.45%的石油焦。
Abstract:Standard Gibbs free energy ΔGθ of sulfur in molten salt chlorination process was calculated by HSC soft. The effects of sulfur content in petroleum coke on grinding, molten salt chlorination process, rough titanium tetrachloride quality and impurity removal were investigated. The results show that the main reaction products in molten salt chlorination system are SO2, COS, SO2Cl2 and SOCl2, which will not affect the continuous and stable operation of molten salt chlorination process, but sulfur content in molten salt, dust slag, tail gas and rough titanium tetrachloride rises. It is difficult to remove sulfur during refining process, and the optimual sulfur content in petroleum coke is 0.45% below.
