Description

Many technological concepts for an alternative aluminium production process have been developed during the last century, because the still utilized Hall-Héroult process is one of the most energy and CO2 intensive industrial processes. However no basic approach was able to prevail in industrial scale. The most promising alternative process is still the carbothermic reduction of alumina, which has been investigated by several companies and researchers. The greatest challenges are the extensive aluminium volatilization occurring at high reaction temperatures, the complicated back-reaction and carbide formation mechanisms as well as critical reactor design issues.
