Abstract
The present disclosure relates to a method of preparing an anisotropic pitch for carbon fiber, and more particularly, to a method of preparing an anisotropic pitch of preparing a pitch having a low softening point by thermally polymerizing heavy oil or residue oil generated in an oil refining process, extracting only a mesogen component, and then heat-treating at a high temperature for a short time. The anisotropic pitch prepared in the present disclosure has advantages of exhibiting the anisotropic content of 100% and controlling the anisotropic content only a simple temperature control as desired and may be used as a precursor of a high value-added carbon material such as carbon fiber and an anode material for a lithium secondary battery.
