Abstract:
Provided is a method for producing a mesophase pitch, the method comprising; a mixing step for mixing a first raw material with a second raw material to produce a mixed raw material, in which the first raw material to be used is a lignite synthetic oil produced by subjecting a mixture comprising raw lignite and water to a hydrothermal treatment under the application of a pressure and the second raw material to be used is a petroleum-based residue having hydrogen donating properties or a reforming product of the petroleum-based residue; a pitch co-synthesis step for heating the mixed raw material under the application of a pressure to perform a pitch co-synthesis reaction; a reaction product collection step for collecting a reaction product produced in the pitch co-synthesis step; and a pitch preparation step for distilling the collected reaction product under a reduced pressure to prepare a mesophase pitch.
