About this document
Alternatives to Hall-Héroult Process by Lalit Gupta is a document available to read on EtoBox.
The document discusses alternatives to the Hall-Héroult process for producing aluminum. It first describes the Hall-Héroult process, which involves electrolysis of alumina dissolved in molten cryolite. However, this process produces toxic and corrosive gases and requires large amounts of energy. The document then summarizes three alternative processes: the sub-chloride process, chloride electrolysis, and the Toth process. The sub-chloride process produces an alloy then reacts it with aluminum chloride vapor
