Zusammenfassung:	Embodiments discloses herein relate to methods of processing coal. A method to process coal includes subjecting raw coal to a liquefaction process to form a pitch resin and refining the pitch resin to produce a mesophase pitch. The method further includes subjecting the mesophase pitch to a low crystallinity spinning process to form a raw fiber. The raw fiber is then further subjected to a stabilization process configured to oxygen cross-link the fiber to form a stabilized fiber and then subjecting the stabilized fiber to a carbonization process to form a carbon fiber.
