  • Pitch for direct spinning into carbon fibers derived from a steam cracker tar feedstock
    Patent number: 4548704
    Abstract: 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. The pitch can be spun directly into carbon fibers.
    Type: Grant
