Method using selected carbons to react with Al2O and Al vapors in the carbothermic production of aluminum
Abstract
In a method for recovering Al from an off-gas (3,4) produced during carbothermic reduction of aluminum utilizing at least one smelter (1,2), the off-gas (3,4) is directed to an enclosed reactor (5) which is fed a supply of wood charcoal (7) having a porosity of from about 50 vol. % to 85 vol. % and an average pore diameter of from about 0.05 .mu.m to about 2.00 .mu.m, where the wood charcoal (7) contacts the off-gas (3,4) to produce at least Al.sub.4 C.sub.3 (6), which is passed back to the smelter (1,2).
