Abstract

PURPOSE: To obtain the titled pitch capable of giving carbon fibers having improved elasticity, strength, etc., by adding a nuclear hydrogenated oil of specific aromatic hydrocarbons to a heavy oil obtained by the fluidized catalytic cracking of petroleum, and the heat-treatment of the resultant mixture.
CONSTITUTION: (B) 10W200pts.vol. hydrogenated oil, obtained by bringing a fraction, produced in preparing a raw material pitch by the heat treatment, and having a boiling point of 160W400°C into contact with hydrogen in the presence of a hydrogenating catalyst, and the nuclear hydrogenation of 10W70% aromatic nuclei in aromatic hydrocarbons contained in the fraction is added to (A) 100pts.vol. heavy oil, obtained by the fluidized catalytic cracking of petroleum, and having a boiling point ≥200°C, and the resultant mixture is then heat-treated at 370W480°C and 2W50kg/cm2.G to give the aimed raw mate rial pitch for carbon fibers. The resultant raw material pitch is then heat-treated to give a precursor pitch, which is melt spun, made infusible and carbonized or further graphitized to afford carbon fibers.
