Preparation of blend from residual oil and lignin, melt spinning of the precursor fiber, preparation of the carbon fibers from the precursor fiber

摘要

The present invention relates to a carbon nanofiber and, more specifically, to production of a lignin complex, a method of producing a free cursor fiber by melt-spinning the complex, a lignin-based carbon fiber using a fiber-free cursor, and a method of producing the same.
