Significance of coal tar pitch for aluminium manufacture

1977-1-1  Coal tar pitch is a main raw material for binding carbon anodes used for aluminium production by smelting flux electrolysis. Electrode pitch is manufactured by continuous distillation of crude coal tar and subsequent thermal treatment of the primarily produced pitch. During the thermal treatment the lower and medium molecular pitch components

The manufacture of high-value carbon from coal-tar pitch

Abstract. World-wide, 17 million ta −1 of coal-tar are obtained as a by product in the chamber coking process for the production of metallurgical coke. Refining of this aromatic raw material yields coal-tar pitch which is the traditional coal-derived starting material for the manufacture of carbon precursors and carbon artefacts.
