ABSTRACT:
Provided is a starting pitch for producing carbon fiber by heat-treating the starting pitch to obtain a precursor pitch, melt-spinning the precursor pitch, then rendering the resultant pitch fiber infusible, followed by carbonization, and further followed by graphitization if required, the starting pitch comprising a mixture of (a) 100 parts by weight of a pitch and (b) 5 to 500 parts by weight of a methanol-insoluble and benzene-soluble component contained in a heavy oil obtained in a fluid catalytic cracking of petroleum, the heavy oil having a boiling range not lower than 200.degree. C.
