Latest Patents

Mikio Oyabu holds a patent for a process for producing carbon fibers. The patent describes a method where fibrous carbon is prepared by dissolving coal in a hydrocarbon solvent under hydrogen pressure. The process involves melt spinning a solvent-refined coal, which is obtained by removing insoluble residues and the solvent from the solution. The resulting fiber is made non-fusible and subjected to carbonization. Additionally, the melt spinning can be enhanced by mixing a highly aromatic bituminous substance with the solvent-refined coal. Alternatively, the coal may be pretreated with a non-aromatic solvent to remove soluble components before melt spinning.
