Abstract
PURPOSE: A raw pitch of low softening temp. capable of easily forming mesophase in the preparation of precursor pitch, which is prepd. by thermally treating a heavy oil produced as a byproduct in the steam cracking of petroleum under hydrogen pressure and specified conditions.
CONSTITUTION: A heavy oil of b.p. ≥200°C produced as a byproduct in the preparation of ethylene, proylene, etc. by the steam cracking of petroleum such as naphtha at about 700W1,200°C, is thermally treated at 400W500°C under hydrogen pressure ≥20kg/cm2 in the absence of hydrogenation catalyst to obtain raw pitch for carbon fiber.
