PURPOSE:A carrier gas containing a carbon compound and an organotransition metal compound is heated to achieve high-efficiency production of carbon fibers by the vapor-phase growth process. CONSTITUTION:N2 gas from a bomb 12 is sent through the by-pass 44 to the reactor tube 38 and its inside is replaced with N2 gas by purging. Then, H2 gas, as a carrier gas, is sent from the bomb 10 to the generator containing a carbon compound such as benzene 28 and the other generator containing an organotransition metal compound such as ferrocene 32. Then, the resultant carrier gas is combined with hydrogen sulfide gas from the bomb 14, then heated in an electric furnace at 600-1,300 deg.C to effect the vapor-phase growth of carbon fibers. |
