process for the production of carbon fiber by direktabscheidung from a gas (vgcf)

摘要

A method for producing vapor grown carbon, including mixing a raw material gas containing an organic compound and an organo-transition metallic compound preliminarily heated preferably to a temperature of 100 to 450° C. with a carrier gas heated preferably to a temperature of 700 to 1,600° C., and introducing the resultant gas mixture into a carbon fiber production zone, wherein preferably a mixture of an aromatic compound and acetylene, ethylene, or butadiene is used as an organic compound. The method can include dissolving the transition metallic compound in a solvent, atomizing the resultant solution into fine droplets, evaporating the solvent in the droplets to thereby obtain fine particles of the transition metal compound, and introducing the drifting particles with an organic compound gas into the carbon fiber production zone. Vapor grown carbon fiber is thereby produced.
