Because of the coal tar supply shortage, the pitch market is becoming very tight due to an increasing demand powered by the aluminum industry. Anthracene oil is the heaviest fraction coming from coal tar distillation with a quality consistency and known chemical composition (metal and QI free), guaranteed by the distilling technology applied on its production. The primary anthracene oil major application is carbon black feedstock. The high aromatic content suggests the potential for other end uses with a higher added value. This paper reports Industrial Quimica del Nalon pilot plant experience in the manufacture of synthetic pitches from anthracene oil. Pitches so obtained shows excellent rheological and wetting properties with minimized environmental and health impact because of its low PAHs concentration and reduced volatility.
