ABSTRACT:
The invention provides a method of producing vapor grown carbon fiber by vapor-phase reaction conducted by supplying carbon source compounds and a catalyst or a catalyst precursor into a heating zone, wherein at least one of the carbon source compound and the catalyst or the catalyst precursor is solid at room temperature and the solid compound is supplied in gas form into the heating zone from a material supplier filled with the solid material alone at a constant amount. The production method according to the invention enables efficient and stable production of vapor phase carbon fiber even by using a high-volume production equipment.
