OSTI ID:5755433
A pitch suitable for carbon fiber manufacture features a pitch having a weight content of between 80 and 100 percent toluene insolubles and greater than about 10 percent quinoline insolubles. The pitch is derived from a deasphaltenated middle fraction of a feedstock. The pitch is characterized as being relatively free of impurities and ash.
