Abstract
Embodiments discloses herein relate to methods of processing coal. A method to process coal includes subjecting raw coal to a liquefaction process effective to form a pitch resin, subjecting the pitch resin to a variable crystallinity spinning process effective to form raw fiber, and subjecting the raw fiber to a carbonization process effective to form a low thermal conductivity carbon fiber.
