提出了一种利用高性能煤（HPC）中1-甲基萘（MN）可溶组分制备各向同性沥青基碳纤维的新方法。MN分馏的程度通过改变分馏温度来控制。在60 ℃下从HPC获得的MN可溶性级分在通过薄层蒸发除去挥发性物质后具有优异的可纺性。此外，随后从MN可溶性部分衍生的纤维具有令人满意的机械性能，在加热至800摄氏度5分钟后，平均拉伸强度为1150 MPa。（C）2016 Elsevier Ltd.保留所有权利。
A cost-effective method for producing an isotropic pitch-based carbon fiber using the 1-methylnaphthalene (MN) soluble fraction of Hyper-coal (HPC) was newly developed. The extent of MN fractionation was controlled by altering the fractionation temperatures. The MN soluble fraction obtained from HPC at 60 degrees C had excellent spinnability after the removal of volatile matter by thin layer evaporation. Additionally, the fiber that was subsequently derived from the MN soluble fraction had satisfactory mechanical properties with an averaged tensile strength of 1150 MPa after heating to 800 degrees C for 5 min.
