摘要: 运用HSC软件对含钛矿物加碳氯化的多元、多相、多反应的复杂体系进行了还原平衡组份的计算与分析. 热力学计算表明,一定组成的含钛矿物在200℃的较低温条件下可完全转化为四氯化钛. 在理论配比条件下,含钛矿物均可完全反应. 在800~1600℃的温度范围内,反应的产物均为气相. 平衡组份的计算结果能够反映含钛矿物氯化的工业生产实际,为进一步优化含钛矿物加碳氯化还原反应的工艺提供了依据.

Abstract: The equilibrium compositions of the multi-component, multi-phase and multi-reaction system of carbochlorination of titanium-bearing ores are calculated with HSC, a computational chemistry software. The thermodynamic equilibrium calculation of the reaction system shows that a complete conversion of titanium-bearing ores is feasible at a temperature near 200℃. At temperatures ranging from 800 to 1600℃, the products of the reaction system are all in gaseous phase. Thermodynamic analysis accords with the industrial practice. The simulated results provide reasonable scientific basis for improving suitable technological conditions of the carbochlorination reduction.
