Method and reactor for producing aluminum by carbothermic reduction of alumina.

摘要

Process for carbothermic production of aluminum where a molten bath comprising aluminum carbide in the low temperature compartment (2), molten bath passing into a high temperature compartment (3) occurs where carbide aluminum reacts with alumina to produce aluminum which forms a layer above a molten slag; wherein the low temperature compartment (2) and high temperature (3) are located in a common reaction vessel (1) and the low temperature compartment (2) it is separated from the high temperature compartment (3) by a partition underflow (4, 4 '', 4 '') having an opening (4''E, 4 '' '' e) in the wall; the molten bath produced in the low temperature compartment (2) circulates continuously under the partition wall into the high temperature compartment (3), wherein the wall is hollow and additional carbon material is supplied to the current through under the partition (4, 4 '', 4 '').
