Starting pitches for carbon fibers |
| abstract |
STARTING PITCHES FOR CARBON FIBERS Abstract of the disclosure: A starting pitch for carbon fibers, obtained by (A) mixing together (1) a heavy fraction oil boiling at not lower than 200°C obtained at the time of fluidized catalytic cracking of petroleum, (2) a hydrogenated oil selected from aromatic hydrocarbons of 2-10 rings having their nuclei partly hydrogenated and specific fractions boiling at 160-650°C and containing such aromatic hydrocarbons and (3) a heavy fraction oil boiling at not lower than 200°C obtained at the time of steam cracking of petroleum, to form a mixture of the oils (1), (2) and (3), and then (B) heat treating the thus formed oil mixture at 370-480°C and 2-50 Kg/cm2?G thereby to obtain the starting pitch. |
