ABSTRACT:
A process and a product of the process for preparing a pitch suitable for carbon artifact manufacture features a pitch having a weight content of between 80 and 100 percent toluene insolubles. The pitch is derived from a substantially deasphaltenated middle fraction of a feedstock, such as a coal distillate. The middle fraction is rich in 3, 4, 5 and 6 polycondensed aromatic rings. The pitch is characterized as being relatively free of impurities and ash.
