1 Abstract

A process is described for preparing a highly anisotropic aromatic pitch characterized by a high content of toluene insolubles, a low melting point, a low viscosity, and low content of quinoline insolubles by heat soaking a petroleum pitch derived from catalytic cracking residue at high temperatures for a short time followed by stripping the distillable oils. The pitch made in accordance with this process will yield a highly anisotropic carbon on carbonization at elevated temperatures.
