摘　　要：以煤加氢热解沥青为原料，采用空气氧化和氮气吹扫处理，制备了可纺沥青，收率超过70％。可纺沥青经过纺丝、预氧化和炭化，制得通用级沥青碳纤维。实验结果表明，沥青碳纤维直径12．2um、抗拉强度623MPa、模量30．5GPa、伸长率2．05％。A spinnable pitch for general carbon fiber was prepared with coal hydrogenation pyrolysis asphalt after air oxidation and N2 blowing with a high yeild of more than 70 %. The spinnable pitch was then used to prepare general pitch carbon fiber after spinning, preoxidation, and carbonization. The result showed that general pitch carbon fiber possessed good capabilities with a diameter of 12.2 um, a tensile strength of 623 MPa, a stretch modulus of 30.5GPa, and a tensile stretch 2.05%.
