U.S. Aluminum Production Energy Requirements: Historical
The minimum theoretical energy requirement to manufacture a carbon anode is the energy necessary to convert the coal tar pitch by destructive distillation to a coke-based binder. Approximately one-third of the pitch binder mass is lost in the baking process (UCAR Carbon Company, Inc). The fuel energy value of the lost pitch, 0.75 kWh/kgReducing the energy consumption of manufacturing processes and machine tools can considerably affect the environmental and economic impact of industrial activities.
