| 摘 要： | 用碳热氯化歧化法对从含铝原料中炼铝过程进行了热力学分析,该过程分为三个步骤:首先,固态AlCl3在低温下升华得到AlCl3或Al2Cl6气体,升华气体经导气管进入高温反应器内;其次,Al2Cl6可能直接参与碳热氯化反应,也可能分解得到AlCl3气体,AlCl3再参与碳热歧化反应生成低价氯化铝AlCl;最后,AlCl在低温区歧解得到金属铝与AlCl3气体。实验结果表明:在12Pa~50Pa,353K~363K条件下,低温时固态AlCl3升华,得到的是Al2Cl6气体,而非AlCl3气体;升华得到的Al2Cl6气体进入高温区,在10Pa~100Pa,560K~615K时发生分解得到AlCl3气体;AlCl3气体参与了碳热氯化反应,而非Al2Cl6气体参与碳热氯化反应。

| Abstract: | In this paper,the thermodynamic of the process of producing aluminium by carbothemic-chloride reaction from alumina,carbon and AlCl3 has been carried out.The whole process is divided into three steps: firstly,AlCl3 solid sublime into Al2Cl6 or AlCl3 gas at low temperature,secondly,Al2Cl6 or AlCl3 gas(Al2Cl6 decomposition),Al2O3 and C take place carbothemic-chloride reaction and format AlCl at high temperature;thirdly, AlCl disproportionate into Al and AlCl3 at low temperature.The results of the experiments ... |
