Aluminum

During aluminium manufacturing, the final stage of the process is to convert alumina or alumina oxide to aluminum by electrolytic Hall-Héroult smelting process. In this electrolysis process, an electrolysis pot is used, which has positive electrode anode and negative electrode or carbon lining. The requirement of anode is about 450Kg/MT of aluminium produced. The anode is made up of petroleum coke. For binding of the petroleum coke, coal tar-based binder pitch is used. Mixture of petroleum coke, aggregate, and coal tar pitch binder is moulded into blocks and baked in furnace high temperature to form anode. Epsilon produces the high-end binder grade pitch for this application.
