VAPOR-GROWN CARBON FIBER AND PRODUCTION PROCESS THEREOF

摘要

The present invention provides a process for producing a vapor-grown carbon fiber by supplying a raw material at least containing a carbon source and a catalyst and/or catalyst precursor compound into a heating zone, wherein the raw material further containing an oxygen-containing carbon source compound which is selected from the group consisting of ketones and ethers. The process for producing a vapor-grown carbon fiber according to the present invention does not leave a residue in a reaction device because a raw material used contains a particular oxygen-containing carbon source compound and, thereby, can continuously produce a vapor-grown carbon fiber.
