Abstract

본 발명은 섬유상 활성탄소의 제조방법에 관한 것으로서, 특히 등방성 피치계 탄소섬유를 공기산화한 다음 탄화처리를 함이 없이 직접 수중기와 질소의 혼합가스로 활성화시켜 표면적이 넓고 흡착력이 우수하며 혼합물질을 선택적으로 분리할 수 있는 섬유상 활성탄소를 고수율로 제조할 수 있는 방법에 관한 것이다.The present invention relates to a method for producing fibrous activated carbon, and in particular, by air oxidation of isotropic pitch-based carbon fibers and then directly activated by a mixed gas of water and nitrogen without carbonization treatment, the surface area is wide and the adsorptivity is excellent, and the mixture quality is improved. It relates to a method for producing a fibrous activated carbon that can be selectively separated in a high yield.
