Latest Patents

Kamishita's latest patents include a method of producing precursor pitches for carbon fibers. This method involves dissolving coal tar pitch in a specific solvent to eliminate solvent insoluble matter, followed by distillation to obtain a purified pitch devoid of free carbon. The purified pitch is then heat-treated to yield the desired precursor pitch. Another patent details a method of producing a precursor pitch through hydrogenation of soft or middle tar pitch. This process results in a hydrogenated pitch that contains no free carbon and high molecular weight components. The hydrogenation occurs in the presence of tetralin at temperatures between 400°C and 450°C, with subsequent heat treatment conducted in an inert gas atmosphere at temperatures ranging from 450°C to 500°C and under reduced pressure.
