A spinnable pitch was developed from the tetrahydrofuran-soluble fractions (THFS) of hyper coal (HPC) and used to prepare carbon fibers. THFS-derived pitch from bituminous coal-derived HPC showed excellent spinnability and the obtained carbon fibers had a tensile strength of over 800 MPa with a diameter of 13 mu m following heat treatment at 800 degrees C for 5 min. Thus, HPC was shown to be a useful alternative precursor for the preparation of low-cost and general-performance carbon fibers. (C) 2015 The Korean Society of Industrial and Engineering Chemistry.
