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 cracking petroleum with stream, and heat-treating the resultant mixture pressure.
CONSTITUTION: (B) 10W200pts.vol. hydrogenated oil, obtained by bringing a fraction, produced in heat-treating a raw material pitch, 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 cracking petroleum with steam, and having a boiling point ≥200°C, and heat-treating the resultant mixture is then heat-treated at 370W480°C and a pressure of 2W50kg/cm2.G is used to give the aimed raw material pitch for carbon fibers. The raw material pitch is heat-treated to afford a precursor pitch, which is then melt spun, made infusible and carbonized or further graphitized to give carbon fibers.
