Abstract
Binder pitch is prepared by combining a petroleum aromatic mineral oil thermal tar and super finely subdivided calcined premium coke particles. The petroleum aromatic mineral oil thermal tar is obtained by hydrotreating, thermally cracking and vacuum distilling an aromatic mineral oil. Additionally, the aromatic mineral oil thermal tar may be subjected to heat soaking.
