反应热力学对研究二氧化钛加碳氯化反应具有指导作用。运用HSC软件通过计算对二氧化钛加碳氯化的CO／CO2比值、配碳比等进行了讨论,结果表明低温下加碳氯化反应的相关产物为CO2,而高温下为CO。产物TiCl4含量在整个温度范围内保持稳定。当配碳比较高时,碳的反应不完全,存在过量;较低时,不利于TiO2的完全反应。通过对工业TiCl4生产CO／CO2 比值研究,发现CO／CO2比值不完全与平衡态下的CO／CO2比值一致。同时对低价钛氧化物的生成进行了探讨,计算表明在温度低于1 100℃时不会生成低价钛氧化物。通过以上研究为进一步优化加碳氯化反应提供了依据。
Reaction thermodynamics can guide the study of titanium dioxide and carbochlorination. Using the HSC software, we calculated the CO / CO2 ratio of carbon dioxide to carbon dioxide and calculated the ratio of carbon to carbon dioxide. The results show that the product of carbonation is CO 2 at low temperature and CO at high temperature. The product TiCl4 content remains stable over the entire temperature range. When the ratio of carbon is high, the reaction of carbon is incomplete and there is excess; when it is low, it is unfavorable to the complete reaction of TiO2. Through the study on the ratio of CO / CO2 produced by industrial TiCl4, it is found that the CO / CO2 ratio is not completely consistent with the CO / CO2 ratio at equilibrium. At the same time, the formation of low-cost titanium oxide was discussed. The calculation shows that low-cost titanium oxide will not be formed when the temperature is lower than 1,100 ℃. Through the above studies provide a basis for further optimization of carburized reaction.
