나프타 분해 잔유물을 반응기에 넣고 질소와 같은 불활성 가스를 통과시키면서 250-450℃의 온도에서 2-8시간 열처리하여 연화점 200-270℃, 벤젠 불용분 30-60중량%, 퀴놀린 불용분이 0.5중량%이하인 광학적으로 동방성 조직을 지닌 핏치를 제조하고; 동방성 핏치를 250-350℃의 방사온도에서 용융 압축방사하여 핏치섬유를 제조하고; 핏치섬유를 공기와 같은 산화성 가스분위기하에서 0.1-10℃/min의 승온속도 및 200-400℃의 온도하에 0-90분간 유지시켜 불융화 섬유를 제조하고, 불융화 섬유를 5-50℃/min의 승온속도로 900-1300℃까지 승온후 0-60분간 유지하여 탄화시키는 단계로 이루어진 동방성 탄소섬유의 제조방법.The naphtha cracked residue is placed in a reactor and heat-treated at a temperature of 250-450 ° C. for 2-8 hours while passing through an inert gas such as nitrogen to give a softening point of 200-270 ° C., 30-60% by weight of benzene insolubles and 0.5% by weight of quinoline insolubles. Preparing a pitch with optically isotropic tissue; An isotropic pitch was melt compressed and spun at a spinning temperature of 250-350 ° C. to produce pitch fibers; The pitch fibers are kept at an elevated temperature of 0.1-10 ° C./min and 0-90 minutes at a temperature of 200-400 ° C. under an oxidizing gas atmosphere such as air to prepare incompatible fibers, and the incompatible fibers are 5-50 ° C./min. Method of producing an isotropic carbon fiber comprising the step of carbonizing by maintaining a 0-60 minutes after the temperature is raised to 900-1300 ℃ at a temperature increase rate. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
