The preparation method of MP includes: separating components with a molecular weight distribution (MWD) of 400 to 1,000 from a heavy oil raw material through size-exclusion chromatography (SEC); subjecting the components to ion-exchange chromatography (IEC) to obtain modified feedstock oil, where, the components are passed through macroporous cation-exchange and anion-exchange resins in sequence to remove acidic and alkaline components; and subjecting the modified feedstock oil to thermal polycondensation and carbonization to obtain high-quality MP with prominent spinnability. With high mesophase content, low softening point, low viscosity, and prominent meltability and spinnability, the obtained MP is a high-quality raw material for preparing HMCFs. The obtained MP can be subjected to melt spinning, pre-oxidation, carbonization, and graphitization to obtain an MP-based HMCF.
