Thermodynamic calculation and experimental investigation on the Products of carbothermal reduction of Al2O3 under vacuum
Vacuum, 2012Co-Authors: Bin Yang, Chen Xiumin, Wenlong Jiang, Yu QingchunAbstract:Abstract In this research, thermodynamic analysis and XRD were used to study the Products in carbothermal reduction of Al2O3 under vacuum. Gaseous reduction Product, Al(g) or Al2O(g), was produced in carbothermal reduction of Al2O3 at 1623 K under 5–30 Pa, and carried out further reactions with CO(g) to produce Al4O4C, Al4C3, Al2O3 and C. Aluminum Product was produced by carbothermal reduction of Al2O3 at low temperature 1623 K under 5–30 Pa, which was the condensate Product of Al(g) or disproportionation Product of Al2O(g). Aluminum Product in condensation tower would be reduced due to the reactions between Al(g) and CO(g) or Al2O(g) and CO(g).

Investigation of chlorination process in Aluminum Production by carbothermic-chlorination reduction of Al2O3 under vacuum
Vacuum, 2012Co-Authors: Wenzhan Yu, Bin Yang, Wenlong Jiang, Qinchun Yu, Baoqiang XuAbstract:Abstract The chlorination process in Aluminum Production by carbothermic-chlorination reduction of Al 2 O 3 under vacuum has been investigated by XRD, SEM and thermodynamic analysis. The results of thermodynamic calculations indicated that the chlorination of Al 4 C 3 or Al 4 O 4 C possibly proceeded at temperature 1300 °C under 5–50 Pa. The experiment results showed that Aluminum could be produced by the chlorination of Al 4 C 3 or Al 4 O 4 C and the decomposition of AlCl(g). According to the analysis of experiment results, Al 4 C 3 and Al 4 O 4 C were the main reactants participated in chlorination process in Aluminum Production by carbothermic-chlorination reduction of Al 2 O 3 under vacuum. AlCl(g) generated in chlorination of Al 4 C 3 or Al 4 O 4 C would decompose into Al and AlCl 3 (g), and then Aluminum Product would condense in condensation tower.

Carbothermal reduction-chlorination-disproportionation of alumina in vacuum
Transactions of Nonferrous Metals Society of China, 2012Co-Authors: Yue-bin Feng, Bin YangAbstract:The carbothermal reduction-chlorination-disproportionation of alumina in vacuum was investigated by XRD and thermodynamic analysis. The experiments on alumina and graphite at 1643-1843 K in vacuum were carried out. The results demonstrate that AlCl3(g) reacts with Al2O(g) or Al(g) generated from the carbothermal reduction of alumina to form AlCl(g), and the AlCl(g) disproportionates to Aluminum and AlCl3(g) at a lower temperature and the reaction rate of AlCl(g) reaches 90% at 980 K and 100 Pa. The Aluminum can absorb CO to catalyze its disproportionation to C and CO2, and react backward with CO to form Al4C3, Al2O3, C and CO2, resulting in the Aluminum Product containing C, Al4C3 and Al2O3. The impurities in the Aluminum Product decrease as the AlCl(g) disproportionation temperature decreases. AlCl3 condenses at a temperature approximated to the room temperature.
