| titleOfInvention | Method of producing a precursor pitch for carbon fiber |
| abstract | KAWASAKI STEEL 59-44,817 Abstract of the Disclosure A method of producing a precursor pitch for use in the production of carbon fibers is disclosed, which comprises hydrogenating a soft or middle tar pitch to obtain a hydrogenated pitch containing no free carbon and high molecular weight components and then subjecting it to a heat treatment. In this method, the hydrogenation is carried out in the presence of tetralin at a temperature of 400-450°C, and the heat treatment after the removal of solvent insoluble components and solvent is carried out in an inert gas atmosphere at a temperature of 450-500°C under a reduced of 0.1-10 Torr. |
